They have the advantages of high efficiency, energy conservation, environmental protection, low carbon emissions, strong adaptability, and On December 14th, as the Qaidam Basin entered the severe cold season, the lowest temperature dropped to minus 15 degrees Celsius. The Qinghai Oilfield intensified its winter safety hazard inspection and governance. Through multi-dimensional approaches such as full participation in hazard inspection, professional supervision and verification, closed-loop rectification and elimination, and digital empowerment, a "safety protection net" was woven throughout the oilfield's oil and gas production areas. The Qinghai Oilfield closely focused on business areas such as crude oil production, natural gas supply guarantee, and engineering technical services. Guided by the requirements of the "Thunderbolt Action" for safe production and in combination with the winter safety risk preve As of December 3rd, Daqing Oilfield, the world's largest research and production base for tertiary oil recovery, has achieved a tertiary oil recovery output of over 10 million tons in 2025, maintaining an output of over 10 million tons for 24 consecutive years, with a cumulative output of 330 million tons, reaching a new peak in production. Tertiary oil recovery involves injecting chemical substances into oil layers to improve the performance of oil, gas, water, and rock interactions, thereby extracting more crude oil from rock pores. After several generations of hard work, Daqing Oilfield has developed its tertiary oil recovery technology from scratch, from following to leading, and has maintained a world-leading position. It has become the dominant development technology On November 28th, it was learned that the Da'an 1H28-4 well, located in the Linjiang syncline of the Da'an block in western Chongqing, was successfully drilled. With a single run of rotary steering achieving a total footage of 3,190 meters and a horizontal section of 2,575 meters, it not only set a new record for the longest horizontal section in the Da'an block but also established a new domestic record for the rotary steering single-run footage of deep shale gas horizontal wells. The 1H28-4 well, which reached a total depth of 6,915 meters, was drilled by the Daqing Drilling 70241 drilling team. Throughout the drilling process, the Exploration and Development Department of Zhejiang Oilfield fully played the leading role of the client, taking the "design, technology, too On November 24th, the "laser rust removal + automatic anti-corrosion" integrated pipeline production line independently developed by Tiancheng Lide Company of Huabei Oilfield was successfully put into operation and has been running stably.

Through optimizing crude oil processing plans, finely adjusting operation parameters, and enhancing coordination among various facilities On November 3rd, at the well maintenance site of Well West 17-9 in the Downhole Operations Company of Dagang Oilfield, employees completed the operation tasks that previously required the cooperation of two positions by controlling the newly developed automatic pipe pusher device. Traditional minor well maintenance is a labor-intensive industry. On-site employees have been dealing with "iron blocks" such as hydraulic tongs, slips, and oil pipes for years, with high labor intensity and safety risks. During the daily process of raising and lowering oil pipes, well maintenance workers need to lift and lower oil pipes weighing over 100 kilograms onto and off the wellhead operation platform, which is time-consuming, laborious, and poses risks of collision and damage. Based on On October 28th, it was learned from Liaohe Oilfield that after the Shu 5 Combined Station of the oilfield adopted the new-generation low-temperature electric dehydration device, the water content of crude oil leaving the station was stably controlled within 0.3%, and the comprehensive cost per ton of liquid decreased by more than 20%. Dehydrating heavy oil has always been a difficult problem restricting the low-cost development of oilfields. The key and difficulty in achieving low-temperature dehydration lies in demulsification. The technical team of Liaohe Oilfield Design Institute deeply analyzed the physical and chemical properties of heavy oil emulsions, developed a multi-field coupling electric dehydration simulation experimental device, and systematically revealed On October 22nd, at the Laoyema Joint Station of the Oil and Gas Gathering and Transportation Company of Jidong Oilfield, employees used a newly developed carbonization cleaning device for filter cores to clean the filter cores. The cleaning process was both convenient and environmentally friendly. In the oil and gas gathering and transportation production system, the filter cores, which are the core components of the filters, are prone to being clogged by impurities such as crude oil resins, congealed oil, sand, flocs, and dead branches and weeds during use. The traditional manual cleaning method is inefficient, labor-intensive, and accelerates the wear of the filter cores, leading to frequent replacements and high costs. Facing this challenge, technicians actively carr On September 7th, the reporter learned from the Testing Technology Service Branch of Daqing Oilfield that its successfully developed wide area tracer logging technology has achieved a breakthrough in both accuracy and efficiency of reservoir water injection monitoring.

The average efficiency of the test has been improved by 45%, and the average amount of isotope carrier used has been reduced by 83%, providing technical support for the fine development of oil fields. This technology innovatively develops the processes of "anti flocculation coating" and "surface active coating", wh As of now, the Internet of Things (IoT) online rate of the BaiKouQuan Oil Production Plant in Xinjiang Oilfield has remained stable at 98%, with data accuracy reaching 99% and equipment integrity rate maintained at 95%. The plant has shifted from merely "building well" to "managing well" and "utilizing well", laying a solid foundation for the digital and intelligent transformation of the oilfield. The BaiKouQuan Oil Production Plant has upgraded its technology to optimize its management model. In software development, it has added an electronic ledger system and dual-end editing functions, making data recording more accurate and maintenance more convenient, and enhancing the precision and efficiency of inspections. The plant has also moved all alarm settings and interlock As of September 10th, Dagang Oilfield has carried out differentiated water injection management in 40 key blocks, achieving a reduction in natural decline and an increase in oil production of over 30,000 tons during the stage. The natural decline rate has decreased by 1.7 percentage points compared to the same period last year, with significant results in tapping the remaining oil. Currently, Dagang Oilfield is in the ultra-high water cut stage. Long-term water injection has led to increasingly complex reservoir seepage patterns, with highly dispersed remaining oil, making precise characterization more difficult. To address this, researchers have relied on detailed reservoir description results to continuously enhance their understanding of reservoir potential, deeply an On August 25th, it was learned that the Gao166-77 well, drilled by the Fourth Drilling Company of Bohai Drilling, was successfully completed, setting new records for the shortest drilling cycle, the shortest drilling and completion cycle, and the fastest average mechanical drilling rate in the Jidong Oilfield. The Gao166-77 well is a directional well in the Gao66X1 block of the Gaoshanpu Oilfield in the northern part of the Gao Shen area of the Jidong Oilfield. It is located in a complex lithological area, facing multiple construction challenges such as the Guantao bottom conglomerate, black basalt, and large sections of brownish-red mudstone. Based on the high-quality completion of the Gao166-79 well in the early stage, the technicians of the Fourth Drilling Company cont Since the beginning of this year, Daqing Petrochemical Company has been adjusting the material flow in the oil refining area based on the principle of "oil when appropriate, olefin when appropriate, and aromatics when appropriate", optimizing the production of self-produced heavy ethylene feedstock, and achieving efficient operation of the oil refining area facilities. From January to July, the overall ethylene yield increased by 0.12% year-on-year, and the overall yield of ethylene and propylene increased by 0.13% year-on-year, demonstrating significant efficiency gains from the integrated layout of refining and chemical production. Systematically optimizing the structure and enhancing raw material quality. Faced with the dual challenges of blending finished oil and supp On August 5th, with the successful completion of a horizontal well at the Guping 41-52 well site, the number of wells in the Changqing Heshui Oilfield's tight oil block-level horizontal well three-dimensional development area exceeded 650, making it the largest such development area in China. Since its development, the area has produced over 5 million tons of oil, with a cumulative oil production 6.5 times that of the directional well development area. The production uptime of oil wells has increased by 17% year-on-year, marking a new development path for the efficient development of tight oil. The Changqing Heshui Oilfield in Longdong, Gansu Province, is a typical tight oil reservoir with rich resources. However, its poor reservoir properties and weak seepage capacity ha As of now, the Tuha Oilfield has completed 46 various plans for capacity construction and other aspects this year, with the design compliance rate reaching 100% and the effectiveness rate of measures reaching 98%. This has effectively saved drilling and fracturing costs, and the supporting and guaranteeing role of engineering technology has become more prominent. As the oilfield shifts to increasing reserves and production in ultra-deep and unconventional areas, the geological conditions have become more complex, posing higher requirements for engineering technical services. Since the beginning of this year, the engineering technical service units of the Tuha Oilfield have focused on key projects, accelerated technological innovation, and improved service quality.

Tertiary oil recovery involves injecting chemical substances into oil layers to improve the performance of oil, gas, water, and rock interactions, thereby extracting more crude oil from rock pores. After several generations of hard work, Daqing Oilfield has developed its tertiary oil recovery technology from scratch, from following to leading, and has maintained a world-leading position. It has become the dominant development technology On November 28th, it was learned that the Da'an 1H28-4 well, located in the Linjiang syncline of the Da'an block in western Chongqing, was successfully drilled. With a single run of rotary steering achieving a total footage of 3,190 meters and a horizontal section of 2,575 meters, it not only set a new record for the longest horizontal section in the Da'an block but also established a new domestic record for the rotary steering single-run footage of deep shale gas horizontal wells. The 1H28-4 well, which reached a total depth of 6,915 meters, was drilled by the Daqing Drilling 70241 drilling team. Throughout the drilling process, the Exploration and Development Department of Zhejiang Oilfield fully played the leading role of the client, taking the "design, technology, too On November 24th, the "laser rust removal + automatic anti-corrosion" integrated pipeline production line independently developed by Tiancheng Lide Company of Huabei Oilfield was successfully put into operation and has been running stably.

To overcome the problems of high environmental risks, low efficiency, and unstable quality, Tiancheng Lide Company of Huabei Oilfield conducted on-site investigations at oilfield pipeline construction sites, construction units, and anti-corrosion manufacturers, systematically analyzed the l On November 12th, it was learned that a well at the shale oil fracturing site in the main oilfield area of Longdong in Changqing Oilfield successfully completed the carbon dioxide energy-enhanced fracturing operation and simultaneously achieved multiple integrated tests including casing external optical fiber monitoring, wellbore digital data collection, and dual-well microseismic monitoring under the high-temperature and high-pressure environment at a depth of 3,602 meters. Technical data shows that all indicators exceeded the design targets, and the implementation effect was significant. With this, the first domestic shale oil carbon dioxide energy-enhanced fracturing comprehensive monitoring test site has been officially established, marking an important breakthrough b As temperatures in Northeast China continue to drop, the pressure to ensure a steady supply of low pour point diesel has been increasing. Liaoyang Petrochemical has closely followed market demand changes, adjusted resource allocation, and optimized production plans to significantly increase the output of low pour point diesel. As of now, the daily average output of -35 diesel at Liaoyang Petrochemical has reached 2,000 tons, effectively meeting market demands. Facing the winter market demand, Liaoyang Petrochemical has ramped up production, making the increase of low pour point diesel a key focus of its current production organization. Through optimizing crude oil processing plans, finely adjusting operation parameters, and enhancing coordination among various facilities On November 3rd, at the well maintenance site of Well West 17-9 in the Downhole Operations Company of Dagang Oilfield, employees completed the operation tasks that previously required the cooperation of two positions by controlling the newly developed automatic pipe pusher device. Traditional minor well maintenance is a labor-intensive industry. On-site employees have been dealing with "iron blocks" such as hydraulic tongs, slips, and oil pipes for years, with high labor intensity and safety risks. During the daily process of raising and lowering oil pipes, well maintenance workers need to lift and lower oil pipes weighing over 100 kilograms onto and off the wellhead operation platform, which is time-consuming, laborious, and poses risks of collision and damage. Based on On October 28th, it was learned from Liaohe Oilfield that after the Shu 5 Combined Station of the oilfield adopted the new-generation low-temperature electric dehydration device, the water content of crude oil leaving the station was stably controlled within 0.3%, and the comprehensive cost per ton of liquid decreased by more than 20%. Dehydrating heavy oil has always been a difficult problem restricting the low-cost development of oilfields. The key and difficulty in achieving low-temperature dehydration lies in demulsification. The technical team of Liaohe Oilfield Design Institute deeply analyzed the physical and chemical properties of heavy oil emulsions, developed a multi-field coupling electric dehydration simulation experimental device, and systematically revealed On October 22nd, at the Laoyema Joint Station of the Oil and Gas Gathering and Transportation Company of Jidong Oilfield, employees used a newly developed carbonization cleaning device for filter cores to clean the filter cores. The cleaning process was both convenient and environmentally friendly. In the oil and gas gathering and transportation production system, the filter cores, which are the core components of the filters, are prone to being clogged by impurities such as crude oil resins, congealed oil, sand, flocs, and dead branches and weeds during use. The traditional manual cleaning method is inefficient, labor-intensive, and accelerates the wear of the filter cores, leading to frequent replacements and high costs. Facing this challenge, technicians actively carr On September 7th, the reporter learned from the Testing Technology Service Branch of Daqing Oilfield that its successfully developed wide area tracer logging technology has achieved a breakthrough in both accuracy and efficiency of reservoir water injection monitoring. This technology is the first of its kind in China and can effectively identify water absorbing layers with an injection depth of only 0.2 meters and a water injection volume of 0.3 cubic meters per day. The average efficiency of the test has been improved by 45%, and the average amount of isotope carrier used has been reduced by 83%, providing technical support for the fine development of oil fields.

The plant has shifted from merely "building well" to "managing well" and "utilizing well", laying a solid foundation for the digital and intelligent transformation of the oilfield. The BaiKouQuan Oil Production Plant has upgraded its technology to optimize its management model. In software development, it has added an electronic ledger system and dual-end editing functions, making data recording more accurate and maintenance more convenient, and enhancing the precision and efficiency of inspections. The plant has also moved all alarm settings and interlock As of September 10th, Dagang Oilfield has carried out differentiated water injection management in 40 key blocks, achieving a reduction in natural decline and an increase in oil production of over 30,000 tons during the stage. The natural decline rate has decreased by 1.7 percentage points compared to the same period last year, with significant results in tapping the remaining oil. Currently, Dagang Oilfield is in the ultra-high water cut stage. Long-term water injection has led to increasingly complex reservoir seepage patterns, with highly dispersed remaining oil, making precise characterization more difficult. To address this, researchers have relied on detailed reservoir description results to continuously enhance their understanding of reservoir potential, deeply an On August 25th, it was learned that the Gao166-77 well, drilled by the Fourth Drilling Company of Bohai Drilling, was successfully completed, setting new records for the shortest drilling cycle, the shortest drilling and completion cycle, and the fastest average mechanical drilling rate in the Jidong Oilfield. The Gao166-77 well is a directional well in the Gao66X1 block of the Gaoshanpu Oilfield in the northern part of the Gao Shen area of the Jidong Oilfield. It is located in a complex lithological area, facing multiple construction challenges such as the Guantao bottom conglomerate, black basalt, and large sections of brownish-red mudstone.

Faced with the dual challenges of blending finished oil and supp On August 5th, with the successful completion of a horizontal well at the Guping 41-52 well site, the number of wells in the Changqing Heshui Oilfield's tight oil block-level horizontal well three-dimensional development area exceeded 650, making it the largest such development area in China. Since its development, the area has produced over 5 million tons of oil, with a cumulative oil production 6.5 times that of the directional well development area. The production uptime of oil wells has increased by 17% year-on-year, marking a new development path for the efficient development of tight oil. The Changqing Heshui Oilfield in Longdong, Gansu Province, is a typical tight oil reservoir with rich resources. However, its poor reservoir properties and weak seepage capacity ha As of now, the Tuha Oilfield has completed 46 various plans for capacity construction and other aspects this year, with the design compliance rate reaching 100% and the effectiveness rate of measures reaching 98%. This has effectively saved drilling and fracturing costs, and the supporting and guaranteeing role of engineering technology has become more prominent. As the oilfield shifts to increasing reserves and production in ultra-deep and unconventional areas, the geological conditions have become more complex, posing higher requirements for engineering technical services. Since the beginning of this year, the engineering technical service units of the Tuha Oilfield have focused on key projects, accelerated technological innovation, and improved service quality. Engine On July 7th, the author learned that in the first half of this year, the commercial volume of coalbed methane in Huabei Oilfield increased by 45 million cubic meters compared with the same period last year. Huabei Oilfield has been committed to treating the coalbed methane business as an important growth pole for building a comprehensive energy company with a production capacity of 10 million tons of oil equivalent. Since the beginning of this year, Huabei Oilfield has followed the strategy of "developing Qingshui and expanding the periphery", empowered by both self-operation and cooperation, and focused on efficient production increase of coalbed methane, accelerating the construction of a green and intelligent industrial base with "one main and three auxiliary" function On May 21st, in the centralized control room of the refining area of Lanzhou Petrochemical, the internal line operators of the 5 million tons/year atmospheric and vacuum distillation unit were carefully comparing the quality inspection and analysis results. By swiping the mouse at the control points on the screen, they adjusted the external release volume of the atmospheric line again, precisely keeping the freezing point of the jet fuel above the quality index to ensure the maximization of the jet fuel yield. Since the beginning of this year, Lanzhou Petrochemical has been market-oriented, fully implementing the policy of "reducing fuel consumption and increasing navigation", achieving efficient coordination among production, sales and transportation, optimizing the stru It is reported that recently, it was learned from Changsha gas transmission branch of west east gas transmission of national pipe network that the company successfully completed the task of ensuring the supply of natural gas in Hunan Province in winter, and transported 1.625 billion cubic meters of natural gas to Hunan Province, a year-on- year increase of 9.26%. Changsha gas transmission branch of West to east gas transmission of national pipeline network has transported 1.625 billion cubic meters of natural gas to Hunan Province, a year-on-year increase of 9.26%.

The report of the 19th National Congress of the Communist Party of China proposed to "give greater reform autonomy to the free trade pilot zone and explore the construction of free trade ports", and domestic ports, large and small, responded one after another. Zhoushan Port, Tianjin Port and Huizhou Port, as coastal oil ports in the Yangtze River Delta Economic Circle, the Bohai Economic Circle and the Pearl River Delta Economic Circle, play the leading role of the Shanghai Futures Exchange in the oil and gas trade and financial market, and lead the surrounding ports to continuously explore suitable ports for themselves. The oil and gas development path has made the domestic port oi At present, green and low carbon has become the consensus of the mainstream society in the world. The Chinese government has committed to strive to achieve carbon peaking by 2030 and carbon neutrality by 2060. To this end, while vigorously developing non-fossil energy, "removing coal and reducing oil" and gradually reducing the share and quantity of natural gas in energy consumption have become the main theme of the future development of the energy sector. In the context of "dual carbon", the concept of "green finance" is heating up. Some people propose to significantly reduce investment in fossil energy and require financial institutions to stop providing loans for it. The argument that oil and gas is a "sunset industry" has resurfaced. But the completion of the energy tran Water conservancy projects are not only important basic projects, but also important livelihood projects. In the construction of various water conservancy projects, the pressure reducing valve is naturally inseparable. The pressure reducing valve plays an important role in the construction of water pipelines, hydroelectric gates and water pump projects. In the construction of water conservancy projects, if the performance of the pressure reducing valve is not ideal, it may affect the normal delivery and use of the water conservancy project. To create high-standard water conservancy projects, high-quality pressure reducing valves must be guaranteed. The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjus Now our country’s environmental problems are very serious, causing great harm to our lives and production. Government departments have been vigorously rectifying, and constantly promulgating various policies for governance. Under this severe situation, the environmental protection valve industry has also developed very well. Urban sewage treatment equipment has greatly promoted the production and sales of environmentally friendly valves. The water pollution in our country is very serious. Both the ground and groundwater are very polluted. my country's sewage treatment technology is still relatively rudimentary, and the pollution level is far greater than the sewage treatment effect. Now we have realized the seriousness of environmental pollution. The treatment of domestic sewage a It is reported that recently, the LNG filling station and LNG container terminal project of Anhui Wuhu Yangtze River LNG inland receiving (transfer) station project, which is generally contracted by CCCC Second Harbor Institute and participated by CCCC Second Harbor Bureau, has been completed and put into operation.

After putting into operation, it will completely solve the problem of hydrogen source for fuel cells in Qingdao, effectively improve the hydrogen production and supply capacity of Shandong Province, promote the rapid development of hydrogen energy industry in Shandong, and help build "Oriental hydrogen island". Qingdao hydrogen energy resource base project is a major demonstration pilot project of hydrogen The safety of oil storage and transportation has always become an important topic in the oil industry. In order to ensure the safety of oil storage and transportation, oil workers not only need to operate in strict accordance with relevant specifications, but also need to promote the continuous upgrading of storage and transportation tools to ensure safer oil storage and transportation. Oil pump is one of the important tools for oil storage and transportation. High performance and high quality oil pump escorts the safe storage and transportation of oil. The high-quality oil pump moves towards high-end and quality to escort the safe storage and transportation of oil. 1、Take scientific research as the core The performance of oil pump is related to the safety of storage and tr Social development is inseparable from the economic construction of basic industries. Over the past 40 years of reform and opening up, China's industrial production level has been significantly improved, and the market has formed a virtuous cycle mechanism. Especially for industrial products such as valves, the market is optimistic. The sales of products such as regulating valves have increased sharply, and the product technology has been improved more and more. The tightness of the regulating valve directly affects the performance and service life of the product, especially for some key industrial and mining enterprises. In addition to the debate, the international community is more important to support China's development. Especially since the epidemic, considering the actual di As my country's industrial development continues to deepen, the requirements for automation of electrical equipment in industrial production are getting higher and higher. The stable and long-term development of enterprises is inseparable from the support of advanced electrical automation instruments and automation control technology. The scale of industrial production continues to expand. The development of industrial electrical automation instrumentation is stable. The working principle of industrial automation instruments is to use intelligent methods to collect and monitor the information in the production process, which can help the production work to be completed more accurately. Inspection in the production process is a very important link for industrial production, and ind    With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i Recently, it was learned from the national pipe network group that the Zhangjiakou branch project of Shaanxi Beijing line 4 natural gas pipeline started construction on the 10th.

At the meeting, China electrification annual development report 2021 (hereinafter referred to as the report) was released. The report proposes that China's electrification process will advance steadily during the 14th Five Year Plan period, and will remain in the middle and advanced stage of electrification by 2030. The development of electrification will strongly support the realization of carbon peak. By 2060, China's electrification process w It is reported that recently, Qingdao hydrogen energy resource base project, a large hydrogen fuel cell hydrogen supply project in Shandong Province undertaken by Qingdao refining and chemical company affiliated to Sinopec, was completed. The project has an annual hydrogen production capacity of 2250 tons and is expected to be put into operation by the end of December this year. After putting into operation, it will completely solve the problem of hydrogen source for fuel cells in Qingdao, effectively improve the hydrogen production and supply capacity of Shandong Province, promote the rapid development of hydrogen energy industry in Shandong, and help build "Oriental hydrogen island". Qingdao hydrogen energy resource base project is a major demonstration pilot project of hydrogen The safety of oil storage and transportation has always become an important topic in the oil industry. In order to ensure the safety of oil storage and transportation, oil workers not only need to operate in strict accordance with relevant specifications, but also need to promote the continuous upgrading of storage and transportation tools to ensure safer oil storage and transportation. Oil pump is one of the important tools for oil storage and transportation. High performance and high quality oil pump escorts the safe storage and transportation of oil. The high-quality oil pump moves towards high-end and quality to escort the safe storage and transportation of oil. 1、Take scientific research as the core The performance of oil pump is related to the safety of storage and tr Social development is inseparable from the economic construction of basic industries. Over the past 40 years of reform and opening up, China's industrial production level has been significantly improved, and the market has formed a virtuous cycle mechanism. Especially for industrial products such as valves, the market is optimistic. The sales of products such as regulating valves have increased sharply, and the product technology has been improved more and more. The tightness of the regulating valve directly affects the performance and service life of the product, especially for some key industrial and mining enterprises. In addition to the debate, the international community is more important to support China's development. Especially since the epidemic, considering the actual di As my country's industrial development continues to deepen, the requirements for automation of electrical equipment in industrial production are getting higher and higher. The stable and long-term development of enterprises is inseparable from the support of advanced electrical automation instruments and automation control technology. The scale of industrial production continues to expand. The development of industrial electrical automation instrumentation is stable. The working principle of industrial automation instruments is to use intelligent methods to collect and monitor the information in the production process, which can help the production work to be completed more accurately. Inspection in the production process is a very important link for industrial production, and ind    With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i Recently, it was learned from the national pipe network group that the Zhangjiakou branch project of Shaanxi Beijing line 4 natural gas pipeline started construction on the 10th. After completion, the gas supply can cover all winter Olympic venues in Zhangjiakou. The total length of the project is 173.7 km, which is composed of 6 branch lines, 11 off load stations are set along the line, the designed annual gas transmission is 3.2 billion m3, and the total investment is 1.26 billion yuan. After the completion of the project, nearly 9 million cubic meters of natural gas can be transported to Zhangjiakou every day, benefiting about 220000 families in Zhangjiakou and realizing the "county to county connection" of natural gas in Zhangjiakou. The relevant person in charge As an important part of my country's manufacturing industry, the instrument and meter manufacturing industry has played an important role in promoting the country's economic growth and social development. With the continuous development of social economy and technology, my country's instrumentation industry has been advancing all the way in recent years. How much do you know about instrumentation! Instruments and meters are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In detail, instruments and meters have functions such as automatic control, alarm, sig

On January 23, the author learned that the Jilantai Oilfield of the Bayan Branch of Huabei Oilfield has continuously deepened the efficient development management model of old oilfields, constantly optimized the technical system and management mechanism, and all key development indicators are at the leading level in the industry. In 2025, the Jilantai Oilfield was awarded the title of "Efficient Development Oilfield" in the oil and gas new energy sector of the Group Company. In 2025, facing multiple challenges such as complex geological conditions, limitations of conventional development technologies, and high difficulty in efficient development, the Jilantai Oilfield innovatively adopted the development methods of "metamorphic rock basement volume fracturing + bottom wat On January 21st, the Wunan 3-2-13X well of the Tarim Oilfield was officially put into operation. This well successfully completed the lowering of the retrievable electric pump and achieved a qualified trial pumping within the middle of this month. It realized the application of the retrievable electric pump lifting technology at a depth of 2500 meters, providing a new technical approach for the Tarim Oilfield to cope with complex working conditions, significantly reducing maintenance and inspection costs, and improving efficiency. Electric pump lifting is an important artificial lifting method in oilfield crude oil production. As the oil and gas development in the Tarim Oilfield continues, electric pump wells generally face complex production environments such as asphalti On January 5th, a reporter learned from the Oil and Gas Technology Research Institute of Jilin Oilfield that the Jilin Oilfield's intensive overall fracturing technology has focused on the capacity building of conventional oil, precisely exerting its technical support role, and achieving a new breakthrough in the capacity building of old oilfields. Up to now, the Jilin Oilfield has applied this technology to conduct fracturing operations on 448 wells in a year, with a success rate of 98%. The average daily oil production per well has increased by 21% compared to the design, and the project's conversion rate has reached 100%. The secondary development of the low-permeability old oilfields in Jilin Oilfield faces multiple challenges such as complex injection-production patt On December 22, the author learned that the high-temperature heat pump system of the third thermal station, a key supporting project for the western transformation and upgrading of Jilin Petrochemical, was successfully put into operation. It supplies qualified heating and hot water for the 600,000-ton/year styrene and other facilities and factory buildings, marking a revolutionary change in the company's winter heating and heat tracing heat sources. High-temperature heat pumps are devices that transfer heat from low-temperature heat sources to high-temperature heat sources through the circulation of refrigerants driven by electricity. They have the advantages of high efficiency, energy conservation, environmental protection, low carbon emissions, strong adaptability, and On December 14th, as the Qaidam Basin entered the severe cold season, the lowest temperature dropped to minus 15 degrees Celsius. The Qinghai Oilfield intensified its winter safety hazard inspection and governance. Through multi-dimensional approaches such as full participation in hazard inspection, professional supervision and verification, closed-loop rectification and elimination, and digital empowerment, a "safety protection net" was woven throughout the oilfield's oil and gas production areas. The Qinghai Oilfield closely focused on business areas such as crude oil production, natural gas supply guarantee, and engineering technical services. Guided by the requirements of the "Thunderbolt Action" for safe production and in combination with the winter safety risk preve As of December 3rd, Daqing Oilfield, the world's largest research and production base for tertiary oil recovery, has achieved a tertiary oil recovery output of over 10 million tons in 2025, maintaining an output of over 10 million tons for 24 consecutive years, with a cumulative output of 330 million tons, reaching a new peak in production. Tertiary oil recovery involves injecting chemical substances into oil layers to improve the performance of oil, gas, water, and rock interactions, thereby extracting more crude oil from rock pores. After several generations of hard work, Daqing Oilfield has developed its tertiary oil recovery technology from scratch, from following to leading, and has maintained a world-leading position. It has become the dominant development technology On November 28th, it was learned that the Da'an 1H28-4 well, located in the Linjiang syncline of the Da'an block in western Chongqing, was successfully drilled. With a single run of rotary steering achieving a total footage of 3,190 meters and a horizontal section of 2,575 meters, it not only set a new record for the longest horizontal section in the Da'an block but also established a new domestic record for the rotary steering single-run footage of deep shale gas horizontal wells. The 1H28-4 well, which reached a total depth of 6,915 meters, was drilled by the Daqing Drilling 70241 drilling team. Throughout the drilling process, the Exploration and Development Department of Zhejiang Oilfield fully played the leading role of the client, taking the "design, technology, too On November 24th, the "laser rust removal + automatic anti-corrosion" integrated pipeline production line independently developed by Tiancheng Lide Company of Huabei Oilfield was successfully put into operation and has been running stably. This production line adopts a seamless design of "rust removal - anti-corrosion", and through process integration and intelligent upgrading, it achieves clean and efficient production, promoting the "1+1>2" efficiency upgrade of pipeline business. To overcome the problems of high environmental risks, low efficiency, and unstable quality, Tiancheng Lide Company of Huabei Oilfield conducted on-site investigations at oilfield pipeline construction sites, construction units, and anti-corrosion manufacturers, systematically analyzed the l On November 12th, it was learned that a well at the shale oil fracturing site in the main oilfield area of Longdong in Changqing Oilfield successfully completed the carbon dioxide energy-enhanced fracturing operation and simultaneously achieved multiple integrated tests including casing external optical fiber monitoring, wellbore digital data collection, and dual-well microseismic monitoring under the high-temperature and high-pressure environment at a depth of 3,602 meters. Technical data shows that all indicators exceeded the design targets, and the implementation effect was significant. With this, the first domestic shale oil carbon dioxide energy-enhanced fracturing comprehensive monitoring test site has been officially established, marking an important breakthrough b As temperatures in Northeast China continue to drop, the pressure to ensure a steady supply of low pour point diesel has been increasing. Liaoyang Petrochemical has closely followed market demand changes, adjusted resource allocation, and optimized production plans to significantly increase the output of low pour point diesel. As of now, the daily average output of -35 diesel at Liaoyang Petrochemical has reached 2,000 tons, effectively meeting market demands. Facing the winter market demand, Liaoyang Petrochemical has ramped up production, making the increase of low pour point diesel a key focus of its current production organization. Through optimizing crude oil processing plans, finely adjusting operation parameters, and enhancing coordination among various facilities On November 3rd, at the well maintenance site of Well West 17-9 in the Downhole Operations Company of Dagang Oilfield, employees completed the operation tasks that previously required the cooperation of two positions by controlling the newly developed automatic pipe pusher device. Traditional minor well maintenance is a labor-intensive industry. On-site employees have been dealing with "iron blocks" such as hydraulic tongs, slips, and oil pipes for years, with high labor intensity and safety risks. During the daily process of raising and lowering oil pipes, well maintenance workers need to lift and lower oil pipes weighing over 100 kilograms onto and off the wellhead operation platform, which is time-consuming, laborious, and poses risks of collision and damage. Based on On October 28th, it was learned from Liaohe Oilfield that after the Shu 5 Combined Station of the oilfield adopted the new-generation low-temperature electric dehydration device, the water content of crude oil leaving the station was stably controlled within 0.3%, and the comprehensive cost per ton of liquid decreased by more than 20%. Dehydrating heavy oil has always been a difficult problem restricting the low-cost development of oilfields. The key and difficulty in achieving low-temperature dehydration lies in demulsification. The technical team of Liaohe Oilfield Design Institute deeply analyzed the physical and chemical properties of heavy oil emulsions, developed a multi-field coupling electric dehydration simulation experimental device, and systematically revealed On October 22nd, at the Laoyema Joint Station of the Oil and Gas Gathering and Transportation Company of Jidong Oilfield, employees used a newly developed carbonization cleaning device for filter cores to clean the filter cores. The cleaning process was both convenient and environmentally friendly. In the oil and gas gathering and transportation production system, the filter cores, which are the core components of the filters, are prone to being clogged by impurities such as crude oil resins, congealed oil, sand, flocs, and dead branches and weeds during use. The traditional manual cleaning method is inefficient, labor-intensive, and accelerates the wear of the filter cores, leading to frequent replacements and high costs. Facing this challenge, technicians actively carr On September 7th, the reporter learned from the Testing Technology Service Branch of Daqing Oilfield that its successfully developed wide area tracer logging technology has achieved a breakthrough in both accuracy and efficiency of reservoir water injection monitoring. This technology is the first of its kind in China and can effectively identify water absorbing layers with an injection depth of only 0.2 meters and a water injection volume of 0.3 cubic meters per day. The average efficiency of the test has been improved by 45%, and the average amount of isotope carrier used has been reduced by 83%, providing technical support for the fine development of oil fields. This technology innovatively develops the processes of "anti flocculation coating" and "surface active coating", wh As of now, the Internet of Things (IoT) online rate of the BaiKouQuan Oil Production Plant in Xinjiang Oilfield has remained stable at 98%, with data accuracy reaching 99% and equipment integrity rate maintained at 95%. The plant has shifted from merely "building well" to "managing well" and "utilizing well", laying a solid foundation for the digital and intelligent transformation of the oilfield. The BaiKouQuan Oil Production Plant has upgraded its technology to optimize its management model. In software development, it has added an electronic ledger system and dual-end editing functions, making data recording more accurate and maintenance more convenient, and enhancing the precision and efficiency of inspections. The plant has also moved all alarm settings and interlock As of September 10th, Dagang Oilfield has carried out differentiated water injection management in 40 key blocks, achieving a reduction in natural decline and an increase in oil production of over 30,000 tons during the stage. The natural decline rate has decreased by 1.7 percentage points compared to the same period last year, with significant results in tapping the remaining oil. Currently, Dagang Oilfield is in the ultra-high water cut stage. Long-term water injection has led to increasingly complex reservoir seepage patterns, with highly dispersed remaining oil, making precise characterization more difficult. To address this, researchers have relied on detailed reservoir description results to continuously enhance their understanding of reservoir potential, deeply an On August 25th, it was learned that the Gao166-77 well, drilled by the Fourth Drilling Company of Bohai Drilling, was successfully completed, setting new records for the shortest drilling cycle, the shortest drilling and completion cycle, and the fastest average mechanical drilling rate in the Jidong Oilfield. The Gao166-77 well is a directional well in the Gao66X1 block of the Gaoshanpu Oilfield in the northern part of the Gao Shen area of the Jidong Oilfield. It is located in a complex lithological area, facing multiple construction challenges such as the Guantao bottom conglomerate, black basalt, and large sections of brownish-red mudstone. Based on the high-quality completion of the Gao166-79 well in the early stage, the technicians of the Fourth Drilling Company cont Since the beginning of this year, Daqing Petrochemical Company has been adjusting the material flow in the oil refining area based on the principle of "oil when appropriate, olefin when appropriate, and aromatics when appropriate", optimizing the production of self-produced heavy ethylene feedstock, and achieving efficient operation of the oil refining area facilities. From January to July, the overall ethylene yield increased by 0.12% year-on-year, and the overall yield of ethylene and propylene increased by 0.13% year-on-year, demonstrating significant efficiency gains from the integrated layout of refining and chemical production.

In order to ensure the safety of oil storage and transportation, oil workers not only need to operate in strict accordance with relevant specifications, but also need to promote the continuous upgrading of storage and transportation tools to ensure safer oil storage and transportation. Oil pump is one of the important tools for oil storage and transportation. High performance and high quality oil pump escorts the safe storage and transportation of oil. The high-quality oil pump moves towards high-end and quality to escort the safe storage and transportation of oil. 1、Take scientific research as the core The performance of oil pump is related to the safety of storage and tr Social development is inseparable from the economic construction of basic industries. Over the past 40 years of reform and opening up, China's industrial production level has been significantly improved, and the market has formed a virtuous cycle mechanism. Especially for industrial products such as valves, the market is optimistic. The sales of products such as regulating valves have increased sharply, and the product technology has been improved more and more. The tightness of the regulating valve directly affects the performance and service life of the product, especially for some key industrial and mining enterprises. In addition to the debate, the international community is more important to support China's development. Especially since the epidemic, considering the actual di As my country's industrial development continues to deepen, the requirements for automation of electrical equipment in industrial production are getting higher and higher. The stable and long-term development of enterprises is inseparable from the support of advanced electrical automation instruments and automation control technology. The scale of industrial production continues to expand. The development of industrial electrical automation instrumentation is stable. The working principle of industrial automation instruments is to use intelligent methods to collect and monitor the information in the production process, which can help the production work to be completed more accurately. Inspection in the production process is a very important link for industrial production, and ind    With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i Recently, it was learned from the national pipe network group that the Zhangjiakou branch project of Shaanxi Beijing line 4 natural gas pipeline started construction on the 10th. After completion, the gas supply can cover all winter Olympic venues in Zhangjiakou. The total length of the project is 173.7 km, which is composed of 6 branch lines, 11 off load stations are set along the line, the designed annual gas transmission is 3.2 billion m3, and the total investment is 1.26 billion yuan. After the completion of the project, nearly 9 million cubic meters of natural gas can be transported to Zhangjiakou every day, benefiting about 220000 families in Zhangjiakou and realizing the "county to county connection" of natural gas in Zhangjiakou. The relevant person in charge As an important part of my country's manufacturing industry, the instrument and meter manufacturing industry has played an important role in promoting the country's economic growth and social development. With the continuous development of social economy and technology, my country's instrumentation industry has been advancing all the way in recent years. How much do you know about instrumentation! Instruments and meters are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In detail, instruments and meters have functions such as automatic control, alarm, sig The automatic adjustment system of the industrial production process is generally composed of a detector, a regulating valve, an actuator and an adjustment object, and the actuator is an indispensable and important part of it. As the terminal product in the industrial process control system, it plays an irreplaceable role for other products in the automatic control system. From the perspective of the industry, the development speed of the implementation of electric control valves in my country lags behind other control instruments. However, this phenomenon is being changed.

In 2025, the Jilantai Oilfield was awarded the title of "Efficient Development Oilfield" in the oil and gas new energy sector of the Group Company. In 2025, facing multiple challenges such as complex geological conditions, limitations of conventional development technologies, and high difficulty in efficient development, the Jilantai Oilfield innovatively adopted the development methods of "metamorphic rock basement volume fracturing + bottom wat On January 21st, the Wunan 3-2-13X well of the Tarim Oilfield was officially put into operation. This well successfully completed the lowering of the retrievable electric pump and achieved a qualified trial pumping within the middle of this month. It realized the application of the retrievable electric pump lifting technology at a depth of 2500 meters, providing a new technical approach for the Tarim Oilfield to cope with complex working conditions, significantly reducing maintenance and inspection costs, and improving efficiency. Electric pump lifting is an important artificial lifting method in oilfield crude oil production. As the oil and gas development in the Tarim Oilfield continues, electric pump wells generally face complex production environments such as asphalti On January 5th, a reporter learned from the Oil and Gas Technology Research Institute of Jilin Oilfield that the Jilin Oilfield's intensive overall fracturing technology has focused on the capacity building of conventional oil, precisely exerting its technical support role, and achieving a new breakthrough in the capacity building of old oilfields. Up to now, the Jilin Oilfield has applied this technology to conduct fracturing operations on 448 wells in a year, with a success rate of 98%. The average daily oil production per well has increased by 21% compared to the design, and the project's conversion rate has reached 100%. The secondary development of the low-permeability old oilfields in Jilin Oilfield faces multiple challenges such as complex injection-production patt On December 22, the author learned that the high-temperature heat pump system of the third thermal station, a key supporting project for the western transformation and upgrading of Jilin Petrochemical, was successfully put into operation. It supplies qualified heating and hot water for the 600,000-ton/year styrene and other facilities and factory buildings, marking a revolutionary change in the company's winter heating and heat tracing heat sources. High-temperature heat pumps are devices that transfer heat from low-temperature heat sources to high-temperature heat sources through the circulation of refrigerants driven by electricity. They have the advantages of high efficiency, energy conservation, environmental protection, low carbon emissions, strong adaptability, and On December 14th, as the Qaidam Basin entered the severe cold season, the lowest temperature dropped to minus 15 degrees Celsius. The Qinghai Oilfield intensified its winter safety hazard inspection and governance. Through multi-dimensional approaches such as full participation in hazard inspection, professional supervision and verification, closed-loop rectification and elimination, and digital empowerment, a "safety protection net" was woven throughout the oilfield's oil and gas production areas. The Qinghai Oilfield closely focused on business areas such as crude oil production, natural gas supply guarantee, and engineering technical services. Guided by the requirements of the "Thunderbolt Action" for safe production and in combination with the winter safety risk preve As of December 3rd, Daqing Oilfield, the world's largest research and production base for tertiary oil recovery, has achieved a tertiary oil recovery output of over 10 million tons in 2025, maintaining an output of over 10 million tons for 24 consecutive years, with a cumulative output of 330 million tons, reaching a new peak in production. Tertiary oil recovery involves injecting chemical substances into oil layers to improve the performance of oil, gas, water, and rock interactions, thereby extracting more crude oil from rock pores. After several generations of hard work, Daqing Oilfield has developed its tertiary oil recovery technology from scratch, from following to leading, and has maintained a world-leading position. It has become the dominant development technology On November 28th, it was learned that the Da'an 1H28-4 well, located in the Linjiang syncline of the Da'an block in western Chongqing, was successfully drilled. With a single run of rotary steering achieving a total footage of 3,190 meters and a horizontal section of 2,575 meters, it not only set a new record for the longest horizontal section in the Da'an block but also established a new domestic record for the rotary steering single-run footage of deep shale gas horizontal wells. The 1H28-4 well, which reached a total depth of 6,915 meters, was drilled by the Daqing Drilling 70241 drilling team. Throughout the drilling process, the Exploration and Development Department of Zhejiang Oilfield fully played the leading role of the client, taking the "design, technology, too On November 24th, the "laser rust removal + automatic anti-corrosion" integrated pipeline production line independently developed by Tiancheng Lide Company of Huabei Oilfield was successfully put into operation and has been running stably. This production line adopts a seamless design of "rust removal - anti-corrosion", and through process integration and intelligent upgrading, it achieves clean and efficient production, promoting the "1+1>2" efficiency upgrade of pipeline business. To overcome the problems of high environmental risks, low efficiency, and unstable quality, Tiancheng Lide Company of Huabei Oilfield conducted on-site investigations at oilfield pipeline construction sites, construction units, and anti-corrosion manufacturers, systematically analyzed the l On November 12th, it was learned that a well at the shale oil fracturing site in the main oilfield area of Longdong in Changqing Oilfield successfully completed the carbon dioxide energy-enhanced fracturing operation and simultaneously achieved multiple integrated tests including casing external optical fiber monitoring, wellbore digital data collection, and dual-well microseismic monitoring under the high-temperature and high-pressure environment at a depth of 3,602 meters. Technical data shows that all indicators exceeded the design targets, and the implementation effect was significant. With this, the first domestic shale oil carbon dioxide energy-enhanced fracturing comprehensive monitoring test site has been officially established, marking an important breakthrough b As temperatures in Northeast China continue to drop, the pressure to ensure a steady supply of low pour point diesel has been increasing. Liaoyang Petrochemical has closely followed market demand changes, adjusted resource allocation, and optimized production plans to significantly increase the output of low pour point diesel. As of now, the daily average output of -35 diesel at Liaoyang Petrochemical has reached 2,000 tons, effectively meeting market demands. Facing the winter market demand, Liaoyang Petrochemical has ramped up production, making the increase of low pour point diesel a key focus of its current production organization. Through optimizing crude oil processing plans, finely adjusting operation parameters, and enhancing coordination among various facilities On November 3rd, at the well maintenance site of Well West 17-9 in the Downhole Operations Company of Dagang Oilfield, employees completed the operation tasks that previously required the cooperation of two positions by controlling the newly developed automatic pipe pusher device. Traditional minor well maintenance is a labor-intensive industry. On-site employees have been dealing with "iron blocks" such as hydraulic tongs, slips, and oil pipes for years, with high labor intensity and safety risks. During the daily process of raising and lowering oil pipes, well maintenance workers need to lift and lower oil pipes weighing over 100 kilograms onto and off the wellhead operation platform, which is time-consuming, laborious, and poses risks of collision and damage. Based on On October 28th, it was learned from Liaohe Oilfield that after the Shu 5 Combined Station of the oilfield adopted the new-generation low-temperature electric dehydration device, the water content of crude oil leaving the station was stably controlled within 0.3%, and the comprehensive cost per ton of liquid decreased by more than 20%. Dehydrating heavy oil has always been a difficult problem restricting the low-cost development of oilfields. The key and difficulty in achieving low-temperature dehydration lies in demulsification. The technical team of Liaohe Oilfield Design Institute deeply analyzed the physical and chemical properties of heavy oil emulsions, developed a multi-field coupling electric dehydration simulation experimental device, and systematically revealed On October 22nd, at the Laoyema Joint Station of the Oil and Gas Gathering and Transportation Company of Jidong Oilfield, employees used a newly developed carbonization cleaning device for filter cores to clean the filter cores. The cleaning process was both convenient and environmentally friendly. In the oil and gas gathering and transportation production system, the filter cores, which are the core components of the filters, are prone to being clogged by impurities such as crude oil resins, congealed oil, sand, flocs, and dead branches and weeds during use. The traditional manual cleaning method is inefficient, labor-intensive, and accelerates the wear of the filter cores, leading to frequent replacements and high costs. Facing this challenge, technicians actively carr On September 7th, the reporter learned from the Testing Technology Service Branch of Daqing Oilfield that its successfully developed wide area tracer logging technology has achieved a breakthrough in both accuracy and efficiency of reservoir water injection monitoring. This technology is the first of its kind in China and can effectively identify water absorbing layers with an injection depth of only 0.2 meters and a water injection volume of 0.3 cubic meters per day. The average efficiency of the test has been improved by 45%, and the average amount of isotope carrier used has been reduced by 83%, providing technical support for the fine development of oil fields. This technology innovatively develops the processes of "anti flocculation coating" and "surface active coating", wh As of now, the Internet of Things (IoT) online rate of the BaiKouQuan Oil Production Plant in Xinjiang Oilfield has remained stable at 98%, with data accuracy reaching 99% and equipment integrity rate maintained at 95%. The plant has shifted from merely "building well" to "managing well" and "utilizing well", laying a solid foundation for the digital and intelligent transformation of the oilfield. The BaiKouQuan Oil Production Plant has upgraded its technology to optimize its management model. In software development, it has added an electronic ledger system and dual-end editing functions, making data recording more accurate and maintenance more convenient, and enhancing the precision and efficiency of inspections. The plant has also moved all alarm settings and interlock As of September 10th, Dagang Oilfield has carried out differentiated water injection management in 40 key blocks, achieving a reduction in natural decline and an increase in oil production of over 30,000 tons during the stage. The natural decline rate has decreased by 1.7 percentage points compared to the same period last year, with significant results in tapping the remaining oil. Currently, Dagang Oilfield is in the ultra-high water cut stage. Long-term water injection has led to increasingly complex reservoir seepage patterns, with highly dispersed remaining oil, making precise characterization more difficult. To address this, researchers have relied on detailed reservoir description results to continuously enhance their understanding of reservoir potential, deeply an On August 25th, it was learned that the Gao166-77 well, drilled by the Fourth Drilling Company of Bohai Drilling, was successfully completed, setting new records for the shortest drilling cycle, the shortest drilling and completion cycle, and the fastest average mechanical drilling rate in the Jidong Oilfield. The Gao166-77 well is a directional well in the Gao66X1 block of the Gaoshanpu Oilfield in the northern part of the Gao Shen area of the Jidong Oilfield. It is located in a complex lithological area, facing multiple construction challenges such as the Guantao bottom conglomerate, black basalt, and large sections of brownish-red mudstone. Based on the high-quality completion of the Gao166-79 well in the early stage, the technicians of the Fourth Drilling Company cont Since the beginning of this year, Daqing Petrochemical Company has been adjusting the material flow in the oil refining area based on the principle of "oil when appropriate, olefin when appropriate, and aromatics when appropriate", optimizing the production of self-produced heavy ethylene feedstock, and achieving efficient operation of the oil refining area facilities. From January to July, the overall ethylene yield increased by 0.12% year-on-year, and the overall yield of ethylene and propylene increased by 0.13% year-on-year, demonstrating significant efficiency gains from the integrated layout of refining and chemical production. Systematically optimizing the structure and enhancing raw material quality. Faced with the dual challenges of blending finished oil and supp On August 5th, with the successful completion of a horizontal well at the Guping 41-52 well site, the number of wells in the Changqing Heshui Oilfield's tight oil block-level horizontal well three-dimensional development area exceeded 650, making it the largest such development area in China. Since its development, the area has produced over 5 million tons of oil, with a cumulative oil production 6.5 times that of the directional well development area. The production uptime of oil wells has increased by 17% year-on-year, marking a new development path for the efficient development of tight oil. The Changqing Heshui Oilfield in Longdong, Gansu Province, is a typical tight oil reservoir with rich resources. However, its poor reservoir properties and weak seepage capacity ha As of now, the Tuha Oilfield has completed 46 various plans for capacity construction and other aspects this year, with the design compliance rate reaching 100% and the effectiveness rate of measures reaching 98%. This has effectively saved drilling and fracturing costs, and the supporting and guaranteeing role of engineering technology has become more prominent. As the oilfield shifts to increasing reserves and production in ultra-deep and unconventional areas, the geological conditions have become more complex, posing higher requirements for engineering technical services. Since the beginning of this year, the engineering technical service units of the Tuha Oilfield have focused on key projects, accelerated technological innovation, and improved service quality. Engine On July 7th, the author learned that in the first half of this year, the commercial volume of coalbed methane in Huabei Oilfield increased by 45 million cubic meters compared with the same period last year. Huabei Oilfield has been committed to treating the coalbed methane business as an important growth pole for building a comprehensive energy company with a production capacity of 10 million tons of oil equivalent. Since the beginning of this year, Huabei Oilfield has followed the strategy of "developing Qingshui and expanding the periphery", empowered by both self-operation and cooperation, and focused on efficient production increase of coalbed methane, accelerating the construction of a green and intelligent industrial base with "one main and three auxiliary" function On May 21st, in the centralized control room of the refining area of Lanzhou Petrochemical, the internal line operators of the 5 million tons/year atmospheric and vacuum distillation unit were carefully comparing the quality inspection and analysis results. By swiping the mouse at the control points on the screen, they adjusted the external release volume of the atmospheric line again, precisely keeping the freezing point of the jet fuel above the quality index to ensure the maximization of the jet fuel yield. Since the beginning of this year, Lanzhou Petrochemical has been market-oriented, fully implementing the policy of "reducing fuel consumption and increasing navigation", achieving efficient coordination among production, sales and transportation, optimizing the stru It is reported that recently, it was learned from Changsha gas transmission branch of west east gas transmission of national pipe network that the company successfully completed the task of ensuring the supply of natural gas in Hunan Province in winter, and transported 1.625 billion cubic meters of natural gas to Hunan Province, a year-on- year increase of 9.26%.

The report of the 19th National Congress of the Communist Party of China proposed to "give greater reform autonomy to the free trade pilot zone and explore the construction of free trade ports", and domestic ports, large and small, responded one after another. Zhoushan Port, Tianjin Port and Huizhou Port, as coastal oil ports in the Yangtze River Delta Economic Circle, the Bohai Economic Circle and the Pearl River Delta Economic Circle, play the leading role of the Shanghai Futures Exchange in the oil and gas trade and financial market, and lead the surrounding ports to continuously explore suitable ports for themselves. The oil and gas development path has made the domestic port oi At present, green and low carbon has become the consensus of the mainstream society in the world. The Chinese government has committed to strive to achieve carbon peaking by 2030 and carbon neutrality by 2060. To this end, while vigorously developing non-fossil energy, "removing coal and reducing oil" and gradually reducing the share and quantity of natural gas in energy consumption have become the main theme of the future development of the energy sector. In the context of "dual carbon", the concept of "green finance" is heating up. Some people propose to significantly reduce investment in fossil energy and require financial institutions to stop providing loans for it. The argument that oil and gas is a "sunset industry" has resurfaced. But the completion of the energy tran Water conservancy projects are not only important basic projects, but also important livelihood projects. In the construction of various water conservancy projects, the pressure reducing valve is naturally inseparable. The pressure reducing valve plays an important role in the construction of water pipelines, hydroelectric gates and water pump projects. In the construction of water conservancy projects, if the performance of the pressure reducing valve is not ideal, it may affect the normal delivery and use of the water conservancy project. To create high-standard water conservancy projects, high-quality pressure reducing valves must be guaranteed. The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjus Now our country’s environmental problems are very serious, causing great harm to our lives and production. Government departments have been vigorously rectifying, and constantly promulgating various policies for governance. Under this severe situation, the environmental protection valve industry has also developed very well. Urban sewage treatment equipment has greatly promoted the production and sales of environmentally friendly valves. The water pollution in our country is very serious. Both the ground and groundwater are very polluted. my country's sewage treatment technology is still relatively rudimentary, and the pollution level is far greater than the sewage treatment effect. Now we have realized the seriousness of environmental pollution. The treatment of domestic sewage a It is reported that recently, the LNG filling station and LNG container terminal project of Anhui Wuhu Yangtze River LNG inland receiving (transfer) station project, which is generally contracted by CCCC Second Harbor Institute and participated by CCCC Second Harbor Bureau, has been completed and put into operation.

Guided by the requirements of the "Thunderbolt Action" for safe production and in combination with the winter safety risk preve As of December 3rd, Daqing Oilfield, the world's largest research and production base for tertiary oil recovery, has achieved a tertiary oil recovery output of over 10 million tons in 2025, maintaining an output of over 10 million tons for 24 consecutive years, with a cumulative output of 330 million tons, reaching a new peak in production. Tertiary oil recovery involves injecting chemical substances into oil layers to improve the performance of oil, gas, water, and rock interactions, thereby extracting more crude oil from rock pores. After several generations of hard work, Daqing Oilfield has developed its tertiary oil recovery technology from scratch, from following to leading, and has maintained a world-leading position. It has become the dominant development technology On November 28th, it was learned that the Da'an 1H28-4 well, located in the Linjiang syncline of the Da'an block in western Chongqing, was successfully drilled. With a single run of rotary steering achieving a total footage of 3,190 meters and a horizontal section of 2,575 meters, it not only set a new record for the longest horizontal section in the Da'an block but also established a new domestic record for the rotary steering single-run footage of deep shale gas horizontal wells. The 1H28-4 well, which reached a total depth of 6,915 meters, was drilled by the Daqing Drilling 70241 drilling team. Throughout the drilling process, the Exploration and Development Department of Zhejiang Oilfield fully played the leading role of the client, taking the "design, technology, too On November 24th, the "laser rust removal + automatic anti-corrosion" integrated pipeline production line independently developed by Tiancheng Lide Company of Huabei Oilfield was successfully put into operation and has been running stably. This production line adopts a seamless design of "rust removal - anti-corrosion", and through process integration and intelligent upgrading, it achieves clean and efficient production, promoting the "1+1>2" efficiency upgrade of pipeline business. To overcome the problems of high environmental risks, low efficiency, and unstable quality, Tiancheng Lide Company of Huabei Oilfield conducted on-site investigations at oilfield pipeline construction sites, construction units, and anti-corrosion manufacturers, systematically analyzed the l On November 12th, it was learned that a well at the shale oil fracturing site in the main oilfield area of Longdong in Changqing Oilfield successfully completed the carbon dioxide energy-enhanced fracturing operation and simultaneously achieved multiple integrated tests including casing external optical fiber monitoring, wellbore digital data collection, and dual-well microseismic monitoring under the high-temperature and high-pressure environment at a depth of 3,602 meters. Technical data shows that all indicators exceeded the design targets, and the implementation effect was significant. With this, the first domestic shale oil carbon dioxide energy-enhanced fracturing comprehensive monitoring test site has been officially established, marking an important breakthrough b As temperatures in Northeast China continue to drop, the pressure to ensure a steady supply of low pour point diesel has been increasing. Liaoyang Petrochemical has closely followed market demand changes, adjusted resource allocation, and optimized production plans to significantly increase the output of low pour point diesel. As of now, the daily average output of -35 diesel at Liaoyang Petrochemical has reached 2,000 tons, effectively meeting market demands. Facing the winter market demand, Liaoyang Petrochemical has ramped up production, making the increase of low pour point diesel a key focus of its current production organization. Through optimizing crude oil processing plans, finely adjusting operation parameters, and enhancing coordination among various facilities On November 3rd, at the well maintenance site of Well West 17-9 in the Downhole Operations Company of Dagang Oilfield, employees completed the operation tasks that previously required the cooperation of two positions by controlling the newly developed automatic pipe pusher device. Traditional minor well maintenance is a labor-intensive industry. On-site employees have been dealing with "iron blocks" such as hydraulic tongs, slips, and oil pipes for years, with high labor intensity and safety risks. During the daily process of raising and lowering oil pipes, well maintenance workers need to lift and lower oil pipes weighing over 100 kilograms onto and off the wellhead operation platform, which is time-consuming, laborious, and poses risks of collision and damage. Based on On October 28th, it was learned from Liaohe Oilfield that after the Shu 5 Combined Station of the oilfield adopted the new-generation low-temperature electric dehydration device, the water content of crude oil leaving the station was stably controlled within 0.3%, and the comprehensive cost per ton of liquid decreased by more than 20%. Dehydrating heavy oil has always been a difficult problem restricting the low-cost development of oilfields. The key and difficulty in achieving low-temperature dehydration lies in demulsification. The technical team of Liaohe Oilfield Design Institute deeply analyzed the physical and chemical properties of heavy oil emulsions, developed a multi-field coupling electric dehydration simulation experimental device, and systematically revealed On October 22nd, at the Laoyema Joint Station of the Oil and Gas Gathering and Transportation Company of Jidong Oilfield, employees used a newly developed carbonization cleaning device for filter cores to clean the filter cores. The cleaning process was both convenient and environmentally friendly. In the oil and gas gathering and transportation production system, the filter cores, which are the core components of the filters, are prone to being clogged by impurities such as crude oil resins, congealed oil, sand, flocs, and dead branches and weeds during use. The traditional manual cleaning method is inefficient, labor-intensive, and accelerates the wear of the filter cores, leading to frequent replacements and high costs. Facing this challenge, technicians actively carr On September 7th, the reporter learned from the Testing Technology Service Branch of Daqing Oilfield that its successfully developed wide area tracer logging technology has achieved a breakthrough in both accuracy and efficiency of reservoir water injection monitoring. This technology is the first of its kind in China and can effectively identify water absorbing layers with an injection depth of only 0.2 meters and a water injection volume of 0.3 cubic meters per day. The average efficiency of the test has been improved by 45%, and the average amount of isotope carrier used has been reduced by 83%, providing technical support for the fine development of oil fields. This technology innovatively develops the processes of "anti flocculation coating" and "surface active coating", wh As of now, the Internet of Things (IoT) online rate of the BaiKouQuan Oil Production Plant in Xinjiang Oilfield has remained stable at 98%, with data accuracy reaching 99% and equipment integrity rate maintained at 95%. The plant has shifted from merely "building well" to "managing well" and "utilizing well", laying a solid foundation for the digital and intelligent transformation of the oilfield. The BaiKouQuan Oil Production Plant has upgraded its technology to optimize its management model. In software development, it has added an electronic ledger system and dual-end editing functions, making data recording more accurate and maintenance more convenient, and enhancing the precision and efficiency of inspections. The plant has also moved all alarm settings and interlock As of September 10th, Dagang Oilfield has carried out differentiated water injection management in 40 key blocks, achieving a reduction in natural decline and an increase in oil production of over 30,000 tons during the stage. The natural decline rate has decreased by 1.7 percentage points compared to the same period last year, with significant results in tapping the remaining oil. Currently, Dagang Oilfield is in the ultra-high water cut stage. Long-term water injection has led to increasingly complex reservoir seepage patterns, with highly dispersed remaining oil, making precise characterization more difficult. To address this, researchers have relied on detailed reservoir description results to continuously enhance their understanding of reservoir potential, deeply an On August 25th, it was learned that the Gao166-77 well, drilled by the Fourth Drilling Company of Bohai Drilling, was successfully completed, setting new records for the shortest drilling cycle, the shortest drilling and completion cycle, and the fastest average mechanical drilling rate in the Jidong Oilfield. The Gao166-77 well is a directional well in the Gao66X1 block of the Gaoshanpu Oilfield in the northern part of the Gao Shen area of the Jidong Oilfield. It is located in a complex lithological area, facing multiple construction challenges such as the Guantao bottom conglomerate, black basalt, and large sections of brownish-red mudstone. Based on the high-quality completion of the Gao166-79 well in the early stage, the technicians of the Fourth Drilling Company cont Since the beginning of this year, Daqing Petrochemical Company has been adjusting the material flow in the oil refining area based on the principle of "oil when appropriate, olefin when appropriate, and aromatics when appropriate", optimizing the production of self-produced heavy ethylene feedstock, and achieving efficient operation of the oil refining area facilities. From January to July, the overall ethylene yield increased by 0.12% year-on-year, and the overall yield of ethylene and propylene increased by 0.13% year-on-year, demonstrating significant efficiency gains from the integrated layout of refining and chemical production. Systematically optimizing the structure and enhancing raw material quality. Faced with the dual challenges of blending finished oil and supp On August 5th, with the successful completion of a horizontal well at the Guping 41-52 well site, the number of wells in the Changqing Heshui Oilfield's tight oil block-level horizontal well three-dimensional development area exceeded 650, making it the largest such development area in China. Since its development, the area has produced over 5 million tons of oil, with a cumulative oil production 6.5 times that of the directional well development area. The production uptime of oil wells has increased by 17% year-on-year, marking a new development path for the efficient development of tight oil. The Changqing Heshui Oilfield in Longdong, Gansu Province, is a typical tight oil reservoir with rich resources. However, its poor reservoir properties and weak seepage capacity ha As of now, the Tuha Oilfield has completed 46 various plans for capacity construction and other aspects this year, with the design compliance rate reaching 100% and the effectiveness rate of measures reaching 98%. This has effectively saved drilling and fracturing costs, and the supporting and guaranteeing role of engineering technology has become more prominent. As the oilfield shifts to increasing reserves and production in ultra-deep and unconventional areas, the geological conditions have become more complex, posing higher requirements for engineering technical services. Since the beginning of this year, the engineering technical service units of the Tuha Oilfield have focused on key projects, accelerated technological innovation, and improved service quality. Engine On July 7th, the author learned that in the first half of this year, the commercial volume of coalbed methane in Huabei Oilfield increased by 45 million cubic meters compared with the same period last year. Huabei Oilfield has been committed to treating the coalbed methane business as an important growth pole for building a comprehensive energy company with a production capacity of 10 million tons of oil equivalent. Since the beginning of this year, Huabei Oilfield has followed the strategy of "developing Qingshui and expanding the periphery", empowered by both self-operation and cooperation, and focused on efficient production increase of coalbed methane, accelerating the construction of a green and intelligent industrial base with "one main and three auxiliary" function On May 21st, in the centralized control room of the refining area of Lanzhou Petrochemical, the internal line operators of the 5 million tons/year atmospheric and vacuum distillation unit were carefully comparing the quality inspection and analysis results. By swiping the mouse at the control points on the screen, they adjusted the external release volume of the atmospheric line again, precisely keeping the freezing point of the jet fuel above the quality index to ensure the maximization of the jet fuel yield. Since the beginning of this year, Lanzhou Petrochemical has been market-oriented, fully implementing the policy of "reducing fuel consumption and increasing navigation", achieving efficient coordination among production, sales and transportation, optimizing the stru It is reported that recently, it was learned from Changsha gas transmission branch of west east gas transmission of national pipe network that the company successfully completed the task of ensuring the supply of natural gas in Hunan Province in winter, and transported 1.625 billion cubic meters of natural gas to Hunan Province, a year-on- year increase of 9.26%. Changsha gas transmission branch of West to east gas transmission of national pipeline network has transported 1.625 billion cubic meters of natural gas to Hunan Province, a year-on-year increase of 9.26%. Changsha gas transmission branch takes safety production as the foundation, emergency response as the starting point and market development as the driving force to build a solid gas barrier for the rapid It is reported that recently, the first batch of 12 affordable wind power and photovoltaic project connection projects of Inner Mongolia Power Group have been approved, involving 12 photovoltaic wind power projects of more than 10 new energy investment enterprises such as Guodian, Huadian, China Resources and Mingyang, with a total installed capacity of 2.3 million KW, distributed in Ulanqab, Erdos, Bayannur, Wuhai, Alxa and other regions. According to the objectives of "two pioneers" and "two surpasses" clearly put forward in the report of the 11th Party Congress of Inner Mongolia Autonomous Region, Inner Mongolia electric power group gave full play to the advantages of power grid resource allocation, went all out and made active deployment, formulated a new energy grid The port is the window of foreign trade, and oil and gas trading is one of its most important businesses. The report of the 19th National Congress of the Communist Party of China proposed to "give greater reform autonomy to the free trade pilot zone and explore the construction of free trade ports", and domestic ports, large and small, responded one after another. Zhoushan Port, Tianjin Port and Huizhou Port, as coastal oil ports in the Yangtze River Delta Economic Circle, the Bohai Economic Circle and the Pearl River Delta Economic Circle, play the leading role of the Shanghai Futures Exchange in the oil and gas trade and financial market, and lead the surrounding ports to continuously explore suitable ports for themselves. The oil and gas development path has made the domestic port oi At present, green and low carbon has become the consensus of the mainstream society in the world. The Chinese government has committed to strive to achieve carbon peaking by 2030 and carbon neutrality by 2060. To this end, while vigorously developing non-fossil energy, "removing coal and reducing oil" and gradually reducing the share and quantity of natural gas in energy consumption have become the main theme of the future development of the energy sector. In the context of "dual carbon", the concept of "green finance" is heating up. Some people propose to significantly reduce investment in fossil energy and require financial institutions to stop providing loans for it. The argument that oil and gas is a "sunset industry" has resurfaced. But the completion of the energy tran Water conservancy projects are not only important basic projects, but also important livelihood projects. In the construction of various water conservancy projects, the pressure reducing valve is naturally inseparable. The pressure reducing valve plays an important role in the construction of water pipelines, hydroelectric gates and water pump projects. In the construction of water conservancy projects, if the performance of the pressure reducing valve is not ideal, it may affect the normal delivery and use of the water conservancy project. To create high-standard water conservancy projects, high-quality pressure reducing valves must be guaranteed. The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjus Now our country’s environmental problems are very serious, causing great harm to our lives and production. Government departments have been vigorously rectifying, and constantly promulgating various policies for governance. Under this severe situation, the environmental protection valve industry has also developed very well. Urban sewage treatment equipment has greatly promoted the production and sales of environmentally friendly valves. The water pollution in our country is very serious. Both the ground and groundwater are very polluted. my country's sewage treatment technology is still relatively rudimentary, and the pollution level is far greater than the sewage treatment effect. Now we have realized the seriousness of environmental pollution. The treatment of domestic sewage a It is reported that recently, the LNG filling station and LNG container terminal project of Anhui Wuhu Yangtze River LNG inland receiving (transfer) station project, which is generally contracted by CCCC Second Harbor Institute and participated by CCCC Second Harbor Bureau, has been completed and put into operation. The project is located in gao'anwei operation area of Sanshan Port Area, Wuhu City. The main construction contents include the construction of a new 5000 ton LNG filling berth, a 10000 ton LNG container berth, rear tank yard and corresponding supporting facilities. The project is the first inland LNG project in China, which opens up a new idea for the development of clean energy industry in inland ports. It is of great significance to promote the constr In the rubber and plastic industry, as one of the most representative rubbers with excellent comprehensive properties such as oil resistance, physical and mechanical properties and chemical resistance, nitrile rubber is widely used in the manufacture of various oil resistant rubber products, a variety of oil resistant gaskets, gaskets, sleeves, flexible packaging, flexible hoses, printing and dyeing rubber rollers, cable rubber materials, etc. this special synthetic rubber is widely used in automobile, aviation, petroleum It has become an essential elastic material in industries such as copying. In 2019, the consumption of nitrile rubber in automobile and transportation industry is prominent, accounting for more than 50%. China is a large consumption area of nitrile ru "The level of electrification is an important symbol of the progress of modern civilization and an inevitable choice to achieve the goal of 'double carbon'." on November 19, it was said at the China electrification development high-end forum hosted by China Electricity Council and hosted by China Electricity Development Research Institute. At the meeting, China electrification annual development report 2021 (hereinafter referred to as the report) was released. The report proposes that China's electrification process will advance steadily during the 14th Five Year Plan period, and will remain in the middle and advanced stage of electrification by 2030. The development of electrification will strongly support the realization of carbon peak. By 2060, China's electrification process w It is reported that recently, Qingdao hydrogen energy resource base project, a large hydrogen fuel cell hydrogen supply project in Shandong Province undertaken by Qingdao refining and chemical company affiliated to Sinopec, was completed. The project has an annual hydrogen production capacity of 2250 tons and is expected to be put into operation by the end of December this year. After putting into operation, it will completely solve the problem of hydrogen source for fuel cells in Qingdao, effectively improve the hydrogen production and supply capacity of Shandong Province, promote the rapid development of hydrogen energy industry in Shandong, and help build "Oriental hydrogen island". Qingdao hydrogen energy resource base project is a major demonstration pilot project of hydrogen The safety of oil storage and transportation has always become an important topic in the oil industry. In order to ensure the safety of oil storage and transportation, oil workers not only need to operate in strict accordance with relevant specifications, but also need to promote the continuous upgrading of storage and transportation tools to ensure safer oil storage and transportation. Oil pump is one of the important tools for oil storage and transportation. High performance and high quality oil pump escorts the safe storage and transportation of oil. The high-quality oil pump moves towards high-end and quality to escort the safe storage and transportation of oil. 1、Take scientific research as the core The performance of oil pump is related to the safety of storage and tr Social development is inseparable from the economic construction of basic industries. Over the past 40 years of reform and opening up, China's industrial production level has been significantly improved, and the market has formed a virtuous cycle mechanism. Especially for industrial products such as valves, the market is optimistic. The sales of products such as regulating valves have increased sharply, and the product technology has been improved more and more. The tightness of the regulating valve directly affects the performance and service life of the product, especially for some key industrial and mining enterprises. In addition to the debate, the international community is more important to support China's development. Especially since the epidemic, considering the actual di As my country's industrial development continues to deepen, the requirements for automation of electrical equipment in industrial production are getting higher and higher. The stable and long-term development of enterprises is inseparable from the support of advanced electrical automation instruments and automation control technology. The scale of industrial production continues to expand. The development of industrial electrical automation instrumentation is stable. The working principle of industrial automation instruments is to use intelligent methods to collect and monitor the information in the production process, which can help the production work to be completed more accurately. Inspection in the production process is a very important link for industrial production, and ind    With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i Recently, it was learned from the national pipe network group that the Zhangjiakou branch project of Shaanxi Beijing line 4 natural gas pipeline started construction on the 10th. After completion, the gas supply can cover all winter Olympic venues in Zhangjiakou. The total length of the project is 173.7 km, which is composed of 6 branch lines, 11 off load stations are set along the line, the designed annual gas transmission is 3.2 billion m3, and the total investment is 1.26 billion yuan. After the completion of the project, nearly 9 million cubic meters of natural gas can be transported to Zhangjiakou every day, benefiting about 220000 families in Zhangjiakou and realizing the "county to county connection" of natural gas in Zhangjiakou. The relevant person in charge As an important part of my country's manufacturing industry, the instrument and meter manufacturing industry has played an important role in promoting the country's economic growth and social development. With the continuous development of social economy and technology, my country's instrumentation industry has been advancing all the way in recent years. How much do you know about instrumentation! Instruments and meters are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In detail, instruments and meters have functions such as automatic control, alarm, sig The automatic adjustment system of the industrial production process is generally composed of a detector, a regulating valve, an actuator and an adjustment object, and the actuator is an indispensable and important part of it. As the terminal product in the industrial process control system, it plays an irreplaceable role for other products in the automatic control system. From the perspective of the industry, the development speed of the implementation of electric control valves in my country lags behind other control instruments. However, this phenomenon is being changed. Not long ago, China Machinery Industry Federation and China General Machinery Industry Association held a product appraisal of "Hydraulic Actuator for Tank Root Valve and Electro-hydraulic Actu The green development of industry needs innovation. Without innovation, the industry will not progress, and the goal of enterprise development will be difficult to achieve. Green development is not only the need of ecological civilization construction, but also the need of China's development in the new era. The high-quality development of social economy and the improvement of the quality of people's living environment must depend on the industrial progress. If the industrial production mode is relatively backward, such as the problem of dripping and running in the production process, it will produce relatively serious pollution problems, and the development goals of clean production and green industry can not be achieved. In the pharmaceutical industry, if the performance of the Because the tank wall manhole is located in the lower part of the oil tank, the manhole bears a lot of liquid pressure. In order to prevent leakage, the installation quality of the manhole must be strictly required. The flanges and cover plates are processed with sealing water lines, and care should be taken to protect them during construction to avoid oil leakage during use. Make a mark every time the manhole is removed, so as to avoid dislocation during reinstallation and affect the tightness. When installing the nuts on the manhole cover, apply force evenly in pairs to prevent oil leakage caused by deformation of the cover or uneven force. The tank wall manhole is installed in the lower part of the storage tank, and is mainly used for the staff to enter and exit the storage tan

Currently, Dagang Oilfield is in the ultra-high water cut stage. Long-term water injection has led to increasingly complex reservoir seepage patterns, with highly dispersed remaining oil, making precise characterization more difficult. To address this, researchers have relied on detailed reservoir description results to continuously enhance their understanding of reservoir potential, deeply an On August 25th, it was learned that the Gao166-77 well, drilled by the Fourth Drilling Company of Bohai Drilling, was successfully completed, setting new records for the shortest drilling cycle, the shortest drilling and completion cycle, and the fastest average mechanical drilling rate in the Jidong Oilfield. The Gao166-77 well is a directional well in the Gao66X1 block of the Gaoshanpu Oilfield in the northern part of the Gao Shen area of the Jidong Oilfield. It is located in a complex lithological area, facing multiple construction challenges such as the Guantao bottom conglomerate, black basalt, and large sections of brownish-red mudstone. Based on the high-quality completion of the Gao166-79 well in the early stage, the technicians of the Fourth Drilling Company cont Since the beginning of this year, Daqing Petrochemical Company has been adjusting the material flow in the oil refining area based on the principle of "oil when appropriate, olefin when appropriate, and aromatics when appropriate", optimizing the production of self-produced heavy ethylene feedstock, and achieving efficient operation of the oil refining area facilities. From January to July, the overall ethylene yield increased by 0.12% year-on-year, and the overall yield of ethylene and propylene increased by 0.13% year-on-year, demonstrating significant efficiency gains from the integrated layout of refining and chemical production. Systematically optimizing the structure and enhancing raw material quality. Faced with the dual challenges of blending finished oil and supp On August 5th, with the successful completion of a horizontal well at the Guping 41-52 well site, the number of wells in the Changqing Heshui Oilfield's tight oil block-level horizontal well three-dimensional development area exceeded 650, making it the largest such development area in China. Since its development, the area has produced over 5 million tons of oil, with a cumulative oil production 6.5 times that of the directional well development area. The production uptime of oil wells has increased by 17% year-on-year, marking a new development path for the efficient development of tight oil. The Changqing Heshui Oilfield in Longdong, Gansu Province, is a typical tight oil reservoir with rich resources. However, its poor reservoir properties and weak seepage capacity ha As of now, the Tuha Oilfield has completed 46 various plans for capacity construction and other aspects this year, with the design compliance rate reaching 100% and the effectiveness rate of measures reaching 98%. This has effectively saved drilling and fracturing costs, and the supporting and guaranteeing role of engineering technology has become more prominent. As the oilfield shifts to increasing reserves and production in ultra-deep and unconventional areas, the geological conditions have become more complex, posing higher requirements for engineering technical services. Since the beginning of this year, the engineering technical service units of the Tuha Oilfield have focused on key projects, accelerated technological innovation, and improved service quality. Engine On July 7th, the author learned that in the first half of this year, the commercial volume of coalbed methane in Huabei Oilfield increased by 45 million cubic meters compared with the same period last year. Huabei Oilfield has been committed to treating the coalbed methane business as an important growth pole for building a comprehensive energy company with a production capacity of 10 million tons of oil equivalent. Since the beginning of this year, Huabei Oilfield has followed the strategy of "developing Qingshui and expanding the periphery", empowered by both self-operation and cooperation, and focused on efficient production increase of coalbed methane, accelerating the construction of a green and intelligent industrial base with "one main and three auxiliary" function On May 21st, in the centralized control room of the refining area of Lanzhou Petrochemical, the internal line operators of the 5 million tons/year atmospheric and vacuum distillation unit were carefully comparing the quality inspection and analysis results. By swiping the mouse at the control points on the screen, they adjusted the external release volume of the atmospheric line again, precisely keeping the freezing point of the jet fuel above the quality index to ensure the maximization of the jet fuel yield. Since the beginning of this year, Lanzhou Petrochemical has been market-oriented, fully implementing the policy of "reducing fuel consumption and increasing navigation", achieving efficient coordination among production, sales and transportation, optimizing the stru It is reported that recently, it was learned from Changsha gas transmission branch of west east gas transmission of national pipe network that the company successfully completed the task of ensuring the supply of natural gas in Hunan Province in winter, and transported 1.625 billion cubic meters of natural gas to Hunan Province, a year-on- year increase of 9.26%. Changsha gas transmission branch of West to east gas transmission of national pipeline network has transported 1.625 billion cubic meters of natural gas to Hunan Province, a year-on-year increase of 9.26%.

According to the objectives of "two pioneers" and "two surpasses" clearly put forward in the report of the 11th Party Congress of Inner Mongolia Autonomous Region, Inner Mongolia electric power group gave full play to the advantages of power grid resource allocation, went all out and made active deployment, formulated a new energy grid The port is the window of foreign trade, and oil and gas trading is one of its most important businesses. The report of the 19th National Congress of the Communist Party of China proposed to "give greater reform autonomy to the free trade pilot zone and explore the construction of free trade ports", and domestic ports, large and small, responded one after another. Zhoushan Port, Tianjin Port and Huizhou Port, as coastal oil ports in the Yangtze River Delta Economic Circle, the Bohai Economic Circle and the Pearl River Delta Economic Circle, play the leading role of the Shanghai Futures Exchange in the oil and gas trade and financial market, and lead the surrounding ports to continuously explore suitable ports for themselves. The oil and gas development path has made the domestic port oi At present, green and low carbon has become the consensus of the mainstream society in the world. The Chinese government has committed to strive to achieve carbon peaking by 2030 and carbon neutrality by 2060. To this end, while vigorously developing non-fossil energy, "removing coal and reducing oil" and gradually reducing the share and quantity of natural gas in energy consumption have become the main theme of the future development of the energy sector. In the context of "dual carbon", the concept of "green finance" is heating up. Some people propose to significantly reduce investment in fossil energy and require financial institutions to stop providing loans for it. The argument that oil and gas is a "sunset industry" has resurfaced. But the completion of the energy tran Water conservancy projects are not only important basic projects, but also important livelihood projects. In the construction of various water conservancy projects, the pressure reducing valve is naturally inseparable. The pressure reducing valve plays an important role in the construction of water pipelines, hydroelectric gates and water pump projects. In the construction of water conservancy projects, if the performance of the pressure reducing valve is not ideal, it may affect the normal delivery and use of the water conservancy project. To create high-standard water conservancy projects, high-quality pressure reducing valves must be guaranteed. The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjus Now our country’s environmental problems are very serious, causing great harm to our lives and production. Government departments have been vigorously rectifying, and constantly promulgating various policies for governance. Under this severe situation, the environmental protection valve industry has also developed very well. Urban sewage treatment equipment has greatly promoted the production and sales of environmentally friendly valves. The water pollution in our country is very serious. Both the ground and groundwater are very polluted. my country's sewage treatment technology is still relatively rudimentary, and the pollution level is far greater than the sewage treatment effect. Now we have realized the seriousness of environmental pollution. The treatment of domestic sewage a It is reported that recently, the LNG filling station and LNG container terminal project of Anhui Wuhu Yangtze River LNG inland receiving (transfer) station project, which is generally contracted by CCCC Second Harbor Institute and participated by CCCC Second Harbor Bureau, has been completed and put into operation.

China is a large consumption area of nitrile ru "The level of electrification is an important symbol of the progress of modern civilization and an inevitable choice to achieve the goal of 'double carbon'." on November 19, it was said at the China electrification development high-end forum hosted by China Electricity Council and hosted by China Electricity Development Research Institute. At the meeting, China electrification annual development report 2021 (hereinafter referred to as the report) was released. The report proposes that China's electrification process will advance steadily during the 14th Five Year Plan period, and will remain in the middle and advanced stage of electrification by 2030. The development of electrification will strongly support the realization of carbon peak. By 2060, China's electrification process w It is reported that recently, Qingdao hydrogen energy resource base project, a large hydrogen fuel cell hydrogen supply project in Shandong Province undertaken by Qingdao refining and chemical company affiliated to Sinopec, was completed. The project has an annual hydrogen production capacity of 2250 tons and is expected to be put into operation by the end of December this year. After putting into operation, it will completely solve the problem of hydrogen source for fuel cells in Qingdao, effectively improve the hydrogen production and supply capacity of Shandong Province, promote the rapid development of hydrogen energy industry in Shandong, and help build "Oriental hydrogen island". Qingdao hydrogen energy resource base project is a major demonstration pilot project of hydrogen The safety of oil storage and transportation has always become an important topic in the oil industry. In order to ensure the safety of oil storage and transportation, oil workers not only need to operate in strict accordance with relevant specifications, but also need to promote the continuous upgrading of storage and transportation tools to ensure safer oil storage and transportation. Oil pump is one of the important tools for oil storage and transportation. High performance and high quality oil pump escorts the safe storage and transportation of oil. The high-quality oil pump moves towards high-end and quality to escort the safe storage and transportation of oil. 1、Take scientific research as the core The performance of oil pump is related to the safety of storage and tr Social development is inseparable from the economic construction of basic industries. Over the past 40 years of reform and opening up, China's industrial production level has been significantly improved, and the market has formed a virtuous cycle mechanism. Especially for industrial products such as valves, the market is optimistic. The sales of products such as regulating valves have increased sharply, and the product technology has been improved more and more. The tightness of the regulating valve directly affects the performance and service life of the product, especially for some key industrial and mining enterprises. In addition to the debate, the international community is more important to support China's development. Especially since the epidemic, considering the actual di As my country's industrial development continues to deepen, the requirements for automation of electrical equipment in industrial production are getting higher and higher. The stable and long-term development of enterprises is inseparable from the support of advanced electrical automation instruments and automation control technology. The scale of industrial production continues to expand. The development of industrial electrical automation instrumentation is stable. The working principle of industrial automation instruments is to use intelligent methods to collect and monitor the information in the production process, which can help the production work to be completed more accurately. Inspection in the production process is a very important link for industrial production, and ind    With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i Recently, it was learned from the national pipe network group that the Zhangjiakou branch project of Shaanxi Beijing line 4 natural gas pipeline started construction on the 10th. After completion, the gas supply can cover all winter Olympic venues in Zhangjiakou. The total length of the project is 173.7 km, which is composed of 6 branch lines, 11 off load stations are set along the line, the designed annual gas transmission is 3.2 billion m3, and the total investment is 1.26 billion yuan. After the completion of the project, nearly 9 million cubic meters of natural gas can be transported to Zhangjiakou every day, benefiting about 220000 families in Zhangjiakou and realizing the "county to county connection" of natural gas in Zhangjiakou. The relevant person in charge As an important part of my country's manufacturing industry, the instrument and meter manufacturing industry has played an important role in promoting the country's economic growth and social development. With the continuous development of social economy and technology, my country's instrumentation industry has been advancing all the way in recent years. How much do you know about instrumentation! Instruments and meters are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In detail, instruments and meters have functions such as automatic control, alarm, sig The automatic adjustment system of the industrial production process is generally composed of a detector, a regulating valve, an actuator and an adjustment object, and the actuator is an indispensable and important part of it. As the terminal product in the industrial process control system, it plays an irreplaceable role for other products in the automatic control system. From the perspective of the industry, the development speed of the implementation of electric control valves in my country lags behind other control instruments. However, this phenomenon is being changed. Not long ago, China Machinery Industry Federation and China General Machinery Industry Association held a product appraisal of "Hydraulic Actuator for Tank Root Valve and Electro-hydraulic Actu The green development of industry needs innovation. Without innovation, the industry will not progress, and the goal of enterprise development will be difficult to achieve. Green development is not only the need of ecological civilization construction, but also the need of China's development in the new era. The high-quality development of social economy and the improvement of the quality of people's living environment must depend on the industrial progress. If the industrial production mode is relatively backward, such as the problem of dripping and running in the production process, it will produce relatively serious pollution problems, and the development goals of clean production and green industry can not be achieved. In the pharmaceutical industry, if the performance of the Because the tank wall manhole is located in the lower part of the oil tank, the manhole bears a lot of liquid pressure. In order to prevent leakage, the installation quality of the manhole must be strictly required. The flanges and cover plates are processed with sealing water lines, and care should be taken to protect them during construction to avoid oil leakage during use. Make a mark every time the manhole is removed, so as to avoid dislocation during reinstallation and affect the tightness. When installing the nuts on the manhole cover, apply force evenly in pairs to prevent oil leakage caused by deformation of the cover or uneven force. The tank wall manhole is installed in the lower part of the storage tank, and is mainly used for the staff to enter and exit the storage tan It is reported that the 2021 China International Fluid Machinery Exhibition, which is highly anticipated by the industry, has successfully closed in Shanghai Hongqiao National Convention and Exhibition Center. In his speech, oriole, President of China General Machinery Industry Association, said that the International Fluid Machinery Exhibition has witnessed the rapid development of China's fluid machinery industry in the past 20 years, promoted technical exchanges and cooperation among the fluid machinery industries, and made important contributions to the communication of market information and the advancement of Chinese fluid machinery technology.

It realized the application of the retrievable electric pump lifting technology at a depth of 2500 meters, providing a new technical approach for the Tarim Oilfield to cope with complex working conditions, significantly reducing maintenance and inspection costs, and improving efficiency. Electric pump lifting is an important artificial lifting method in oilfield crude oil production. As the oil and gas development in the Tarim Oilfield continues, electric pump wells generally face complex production environments such as asphalti On January 5th, a reporter learned from the Oil and Gas Technology Research Institute of Jilin Oilfield that the Jilin Oilfield's intensive overall fracturing technology has focused on the capacity building of conventional oil, precisely exerting its technical support role, and achieving a new breakthrough in the capacity building of old oilfields. Up to now, the Jilin Oilfield has applied this technology to conduct fracturing operations on 448 wells in a year, with a success rate of 98%. The average daily oil production per well has increased by 21% compared to the design, and the project's conversion rate has reached 100%. The secondary development of the low-permeability old oilfields in Jilin Oilfield faces multiple challenges such as complex injection-production patt On December 22, the author learned that the high-temperature heat pump system of the third thermal station, a key supporting project for the western transformation and upgrading of Jilin Petrochemical, was successfully put into operation. It supplies qualified heating and hot water for the 600,000-ton/year styrene and other facilities and factory buildings, marking a revolutionary change in the company's winter heating and heat tracing heat sources. High-temperature heat pumps are devices that transfer heat from low-temperature heat sources to high-temperature heat sources through the circulation of refrigerants driven by electricity. They have the advantages of high efficiency, energy conservation, environmental protection, low carbon emissions, strong adaptability, and On December 14th, as the Qaidam Basin entered the severe cold season, the lowest temperature dropped to minus 15 degrees Celsius. The Qinghai Oilfield intensified its winter safety hazard inspection and governance. Through multi-dimensional approaches such as full participation in hazard inspection, professional supervision and verification, closed-loop rectification and elimination, and digital empowerment, a "safety protection net" was woven throughout the oilfield's oil and gas production areas. The Qinghai Oilfield closely focused on business areas such as crude oil production, natural gas supply guarantee, and engineering technical services. Guided by the requirements of the "Thunderbolt Action" for safe production and in combination with the winter safety risk preve As of December 3rd, Daqing Oilfield, the world's largest research and production base for tertiary oil recovery, has achieved a tertiary oil recovery output of over 10 million tons in 2025, maintaining an output of over 10 million tons for 24 consecutive years, with a cumulative output of 330 million tons, reaching a new peak in production. Tertiary oil recovery involves injecting chemical substances into oil layers to improve the performance of oil, gas, water, and rock interactions, thereby extracting more crude oil from rock pores. After several generations of hard work, Daqing Oilfield has developed its tertiary oil recovery technology from scratch, from following to leading, and has maintained a world-leading position. It has become the dominant development technology On November 28th, it was learned that the Da'an 1H28-4 well, located in the Linjiang syncline of the Da'an block in western Chongqing, was successfully drilled. With a single run of rotary steering achieving a total footage of 3,190 meters and a horizontal section of 2,575 meters, it not only set a new record for the longest horizontal section in the Da'an block but also established a new domestic record for the rotary steering single-run footage of deep shale gas horizontal wells. The 1H28-4 well, which reached a total depth of 6,915 meters, was drilled by the Daqing Drilling 70241 drilling team. Throughout the drilling process, the Exploration and Development Department of Zhejiang Oilfield fully played the leading role of the client, taking the "design, technology, too On November 24th, the "laser rust removal + automatic anti-corrosion" integrated pipeline production line independently developed by Tiancheng Lide Company of Huabei Oilfield was successfully put into operation and has been running stably. This production line adopts a seamless design of "rust removal - anti-corrosion", and through process integration and intelligent upgrading, it achieves clean and efficient production, promoting the "1+1>2" efficiency upgrade of pipeline business. To overcome the problems of high environmental risks, low efficiency, and unstable quality, Tiancheng Lide Company of Huabei Oilfield conducted on-site investigations at oilfield pipeline construction sites, construction units, and anti-corrosion manufacturers, systematically analyzed the l On November 12th, it was learned that a well at the shale oil fracturing site in the main oilfield area of Longdong in Changqing Oilfield successfully completed the carbon dioxide energy-enhanced fracturing operation and simultaneously achieved multiple integrated tests including casing external optical fiber monitoring, wellbore digital data collection, and dual-well microseismic monitoring under the high-temperature and high-pressure environment at a depth of 3,602 meters. Technical data shows that all indicators exceeded the design targets, and the implementation effect was significant. With this, the first domestic shale oil carbon dioxide energy-enhanced fracturing comprehensive monitoring test site has been officially established, marking an important breakthrough b As temperatures in Northeast China continue to drop, the pressure to ensure a steady supply of low pour point diesel has been increasing. Liaoyang Petrochemical has closely followed market demand changes, adjusted resource allocation, and optimized production plans to significantly increase the output of low pour point diesel. As of now, the daily average output of -35 diesel at Liaoyang Petrochemical has reached 2,000 tons, effectively meeting market demands. Facing the winter market demand, Liaoyang Petrochemical has ramped up production, making the increase of low pour point diesel a key focus of its current production organization. Through optimizing crude oil processing plans, finely adjusting operation parameters, and enhancing coordination among various facilities On November 3rd, at the well maintenance site of Well West 17-9 in the Downhole Operations Company of Dagang Oilfield, employees completed the operation tasks that previously required the cooperation of two positions by controlling the newly developed automatic pipe pusher device. Traditional minor well maintenance is a labor-intensive industry. On-site employees have been dealing with "iron blocks" such as hydraulic tongs, slips, and oil pipes for years, with high labor intensity and safety risks. During the daily process of raising and lowering oil pipes, well maintenance workers need to lift and lower oil pipes weighing over 100 kilograms onto and off the wellhead operation platform, which is time-consuming, laborious, and poses risks of collision and damage. Based on On October 28th, it was learned from Liaohe Oilfield that after the Shu 5 Combined Station of the oilfield adopted the new-generation low-temperature electric dehydration device, the water content of crude oil leaving the station was stably controlled within 0.3%, and the comprehensive cost per ton of liquid decreased by more than 20%. Dehydrating heavy oil has always been a difficult problem restricting the low-cost development of oilfields. The key and difficulty in achieving low-temperature dehydration lies in demulsification. The technical team of Liaohe Oilfield Design Institute deeply analyzed the physical and chemical properties of heavy oil emulsions, developed a multi-field coupling electric dehydration simulation experimental device, and systematically revealed On October 22nd, at the Laoyema Joint Station of the Oil and Gas Gathering and Transportation Company of Jidong Oilfield, employees used a newly developed carbonization cleaning device for filter cores to clean the filter cores. The cleaning process was both convenient and environmentally friendly. In the oil and gas gathering and transportation production system, the filter cores, which are the core components of the filters, are prone to being clogged by impurities such as crude oil resins, congealed oil, sand, flocs, and dead branches and weeds during use. The traditional manual cleaning method is inefficient, labor-intensive, and accelerates the wear of the filter cores, leading to frequent replacements and high costs. Facing this challenge, technicians actively carr On September 7th, the reporter learned from the Testing Technology Service Branch of Daqing Oilfield that its successfully developed wide area tracer logging technology has achieved a breakthrough in both accuracy and efficiency of reservoir water injection monitoring. This technology is the first of its kind in China and can effectively identify water absorbing layers with an injection depth of only 0.2 meters and a water injection volume of 0.3 cubic meters per day. The average efficiency of the test has been improved by 45%, and the average amount of isotope carrier used has been reduced by 83%, providing technical support for the fine development of oil fields. This technology innovatively develops the processes of "anti flocculation coating" and "surface active coating", wh As of now, the Internet of Things (IoT) online rate of the BaiKouQuan Oil Production Plant in Xinjiang Oilfield has remained stable at 98%, with data accuracy reaching 99% and equipment integrity rate maintained at 95%. The plant has shifted from merely "building well" to "managing well" and "utilizing well", laying a solid foundation for the digital and intelligent transformation of the oilfield. The BaiKouQuan Oil Production Plant has upgraded its technology to optimize its management model. In software development, it has added an electronic ledger system and dual-end editing functions, making data recording more accurate and maintenance more convenient, and enhancing the precision and efficiency of inspections. The plant has also moved all alarm settings and interlock As of September 10th, Dagang Oilfield has carried out differentiated water injection management in 40 key blocks, achieving a reduction in natural decline and an increase in oil production of over 30,000 tons during the stage. The natural decline rate has decreased by 1.7 percentage points compared to the same period last year, with significant results in tapping the remaining oil. Currently, Dagang Oilfield is in the ultra-high water cut stage. Long-term water injection has led to increasingly complex reservoir seepage patterns, with highly dispersed remaining oil, making precise characterization more difficult. To address this, researchers have relied on detailed reservoir description results to continuously enhance their understanding of reservoir potential, deeply an On August 25th, it was learned that the Gao166-77 well, drilled by the Fourth Drilling Company of Bohai Drilling, was successfully completed, setting new records for the shortest drilling cycle, the shortest drilling and completion cycle, and the fastest average mechanical drilling rate in the Jidong Oilfield. The Gao166-77 well is a directional well in the Gao66X1 block of the Gaoshanpu Oilfield in the northern part of the Gao Shen area of the Jidong Oilfield. It is located in a complex lithological area, facing multiple construction challenges such as the Guantao bottom conglomerate, black basalt, and large sections of brownish-red mudstone. Based on the high-quality completion of the Gao166-79 well in the early stage, the technicians of the Fourth Drilling Company cont Since the beginning of this year, Daqing Petrochemical Company has been adjusting the material flow in the oil refining area based on the principle of "oil when appropriate, olefin when appropriate, and aromatics when appropriate", optimizing the production of self-produced heavy ethylene feedstock, and achieving efficient operation of the oil refining area facilities. From January to July, the overall ethylene yield increased by 0.12% year-on-year, and the overall yield of ethylene and propylene increased by 0.13% year-on-year, demonstrating significant efficiency gains from the integrated layout of refining and chemical production.

The oil and gas development path has made the domestic port oi At present, green and low carbon has become the consensus of the mainstream society in the world. The Chinese government has committed to strive to achieve carbon peaking by 2030 and carbon neutrality by 2060. To this end, while vigorously developing non-fossil energy, "removing coal and reducing oil" and gradually reducing the share and quantity of natural gas in energy consumption have become the main theme of the future development of the energy sector. In the context of "dual carbon", the concept of "green finance" is heating up. Some people propose to significantly reduce investment in fossil energy and require financial institutions to stop providing loans for it. The argument that oil and gas is a "sunset industry" has resurfaced. But the completion of the energy tran Water conservancy projects are not only important basic projects, but also important livelihood projects. In the construction of various water conservancy projects, the pressure reducing valve is naturally inseparable. The pressure reducing valve plays an important role in the construction of water pipelines, hydroelectric gates and water pump projects. In the construction of water conservancy projects, if the performance of the pressure reducing valve is not ideal, it may affect the normal delivery and use of the water conservancy project. To create high-standard water conservancy projects, high-quality pressure reducing valves must be guaranteed. The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjus Now our country’s environmental problems are very serious, causing great harm to our lives and production. Government departments have been vigorously rectifying, and constantly promulgating various policies for governance. Under this severe situation, the environmental protection valve industry has also developed very well. Urban sewage treatment equipment has greatly promoted the production and sales of environmentally friendly valves. The water pollution in our country is very serious. Both the ground and groundwater are very polluted. my country's sewage treatment technology is still relatively rudimentary, and the pollution level is far greater than the sewage treatment effect. Now we have realized the seriousness of environmental pollution. The treatment of domestic sewage a It is reported that recently, the LNG filling station and LNG container terminal project of Anhui Wuhu Yangtze River LNG inland receiving (transfer) station project, which is generally contracted by CCCC Second Harbor Institute and participated by CCCC Second Harbor Bureau, has been completed and put into operation. The project is located in gao'anwei operation area of Sanshan Port Area, Wuhu City. The main construction contents include the construction of a new 5000 ton LNG filling berth, a 10000 ton LNG container berth, rear tank yard and corresponding supporting facilities. The project is the first inland LNG project in China, which opens up a new idea for the development of clean energy industry in inland ports. It is of great significance to promote the constr In the rubber and plastic industry, as one of the most representative rubbers with excellent comprehensive properties such as oil resistance, physical and mechanical properties and chemical resistance, nitrile rubber is widely used in the manufacture of various oil resistant rubber products, a variety of oil resistant gaskets, gaskets, sleeves, flexible packaging, flexible hoses, printing and dyeing rubber rollers, cable rubber materials, etc. this special synthetic rubber is widely used in automobile, aviation, petroleum It has become an essential elastic material in industries such as copying. In 2019, the consumption of nitrile rubber in automobile and transportation industry is prominent, accounting for more than 50%. China is a large consumption area of nitrile ru "The level of electrification is an important symbol of the progress of modern civilization and an inevitable choice to achieve the goal of 'double carbon'." on November 19, it was said at the China electrification development high-end forum hosted by China Electricity Council and hosted by China Electricity Development Research Institute. At the meeting, China electrification annual development report 2021 (hereinafter referred to as the report) was released. The report proposes that China's electrification process will advance steadily during the 14th Five Year Plan period, and will remain in the middle and advanced stage of electrification by 2030. The development of electrification will strongly support the realization of carbon peak. By 2060, China's electrification process w It is reported that recently, Qingdao hydrogen energy resource base project, a large hydrogen fuel cell hydrogen supply project in Shandong Province undertaken by Qingdao refining and chemical company affiliated to Sinopec, was completed. The project has an annual hydrogen production capacity of 2250 tons and is expected to be put into operation by the end of December this year. After putting into operation, it will completely solve the problem of hydrogen source for fuel cells in Qingdao, effectively improve the hydrogen production and supply capacity of Shandong Province, promote the rapid development of hydrogen energy industry in Shandong, and help build "Oriental hydrogen island". Qingdao hydrogen energy resource base project is a major demonstration pilot project of hydrogen The safety of oil storage and transportation has always become an important topic in the oil industry. In order to ensure the safety of oil storage and transportation, oil workers not only need to operate in strict accordance with relevant specifications, but also need to promote the continuous upgrading of storage and transportation tools to ensure safer oil storage and transportation. Oil pump is one of the important tools for oil storage and transportation. High performance and high quality oil pump escorts the safe storage and transportation of oil. The high-quality oil pump moves towards high-end and quality to escort the safe storage and transportation of oil. 1、Take scientific research as the core The performance of oil pump is related to the safety of storage and tr Social development is inseparable from the economic construction of basic industries. Over the past 40 years of reform and opening up, China's industrial production level has been significantly improved, and the market has formed a virtuous cycle mechanism. Especially for industrial products such as valves, the market is optimistic. The sales of products such as regulating valves have increased sharply, and the product technology has been improved more and more. The tightness of the regulating valve directly affects the performance and service life of the product, especially for some key industrial and mining enterprises. In addition to the debate, the international community is more important to support China's development. Especially since the epidemic, considering the actual di As my country's industrial development continues to deepen, the requirements for automation of electrical equipment in industrial production are getting higher and higher. The stable and long-term development of enterprises is inseparable from the support of advanced electrical automation instruments and automation control technology. The scale of industrial production continues to expand. The development of industrial electrical automation instrumentation is stable. The working principle of industrial automation instruments is to use intelligent methods to collect and monitor the information in the production process, which can help the production work to be completed more accurately. Inspection in the production process is a very important link for industrial production, and ind    With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i Recently, it was learned from the national pipe network group that the Zhangjiakou branch project of Shaanxi Beijing line 4 natural gas pipeline started construction on the 10th. After completion, the gas supply can cover all winter Olympic venues in Zhangjiakou. The total length of the project is 173.7 km, which is composed of 6 branch lines, 11 off load stations are set along the line, the designed annual gas transmission is 3.2 billion m3, and the total investment is 1.26 billion yuan. After the completion of the project, nearly 9 million cubic meters of natural gas can be transported to Zhangjiakou every day, benefiting about 220000 families in Zhangjiakou and realizing the "county to county connection" of natural gas in Zhangjiakou. The relevant person in charge As an important part of my country's manufacturing industry, the instrument and meter manufacturing industry has played an important role in promoting the country's economic growth and social development. With the continuous development of social economy and technology, my country's instrumentation industry has been advancing all the way in recent years. How much do you know about instrumentation! Instruments and meters are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In detail, instruments and meters have functions such as automatic control, alarm, sig The automatic adjustment system of the industrial production process is generally composed of a detector, a regulating valve, an actuator and an adjustment object, and the actuator is an indispensable and important part of it. As the terminal product in the industrial process control system, it plays an irreplaceable role for other products in the automatic control system. From the perspective of the industry, the development speed of the implementation of electric control valves in my country lags behind other control instruments. However, this phenomenon is being changed. Not long ago, China Machinery Industry Federation and China General Machinery Industry Association held a product appraisal of "Hydraulic Actuator for Tank Root Valve and Electro-hydraulic Actu The green development of industry needs innovation. Without innovation, the industry will not progress, and the goal of enterprise development will be difficult to achieve. Green development is not only the need of ecological civilization construction, but also the need of China's development in the new era. The high-quality development of social economy and the improvement of the quality of people's living environment must depend on the industrial progress. If the industrial production mode is relatively backward, such as the problem of dripping and running in the production process, it will produce relatively serious pollution problems, and the development goals of clean production and green industry can not be achieved. In the pharmaceutical industry, if the performance of the Because the tank wall manhole is located in the lower part of the oil tank, the manhole bears a lot of liquid pressure. In order to prevent leakage, the installation quality of the manhole must be strictly required. The flanges and cover plates are processed with sealing water lines, and care should be taken to protect them during construction to avoid oil leakage during use. Make a mark every time the manhole is removed, so as to avoid dislocation during reinstallation and affect the tightness. When installing the nuts on the manhole cover, apply force evenly in pairs to prevent oil leakage caused by deformation of the cover or uneven force. The tank wall manhole is installed in the lower part of the storage tank, and is mainly used for the staff to enter and exit the storage tan It is reported that the 2021 China International Fluid Machinery Exhibition, which is highly anticipated by the industry, has successfully closed in Shanghai Hongqiao National Convention and Exhibition Center. In his speech, oriole, President of China General Machinery Industry Association, said that the International Fluid Machinery Exhibition has witnessed the rapid development of China's fluid machinery industry in the past 20 years, promoted technical exchanges and cooperation among the fluid machinery industries, and made important contributions to the communication of market information and the advancement of Chinese fluid machinery technology.

On January 23, the author learned that the Jilantai Oilfield of the Bayan Branch of Huabei Oilfield has continuously deepened the efficient development management model of old oilfields, constantly optimized the technical system and management mechanism, and all key development indicators are at the leading level in the industry. In 2025, the Jilantai Oilfield was awarded the title of "Efficient Development Oilfield" in the oil and gas new energy sector of the Group Company. In 2025, facing multiple challenges such as complex geological conditions, limitations of conventional development technologies, and high difficulty in efficient development, the Jilantai Oilfield innovatively adopted the development methods of "metamorphic rock basement volume fracturing + bottom wat On January 21st, the Wunan 3-2-13X well of the Tarim Oilfield was officially put into operation. This well successfully completed the lowering of the retrievable electric pump and achieved a qualified trial pumping within the middle of this month. It realized the application of the retrievable electric pump lifting technology at a depth of 2500 meters, providing a new technical approach for the Tarim Oilfield to cope with complex working conditions, significantly reducing maintenance and inspection costs, and improving efficiency. Electric pump lifting is an important artificial lifting method in oilfield crude oil production. As the oil and gas development in the Tarim Oilfield continues, electric pump wells generally face complex production environments such as asphalti On January 5th, a reporter learned from the Oil and Gas Technology Research Institute of Jilin Oilfield that the Jilin Oilfield's intensive overall fracturing technology has focused on the capacity building of conventional oil, precisely exerting its technical support role, and achieving a new breakthrough in the capacity building of old oilfields. Up to now, the Jilin Oilfield has applied this technology to conduct fracturing operations on 448 wells in a year, with a success rate of 98%. The average daily oil production per well has increased by 21% compared to the design, and the project's conversion rate has reached 100%. The secondary development of the low-permeability old oilfields in Jilin Oilfield faces multiple challenges such as complex injection-production patt On December 22, the author learned that the high-temperature heat pump system of the third thermal station, a key supporting project for the western transformation and upgrading of Jilin Petrochemical, was successfully put into operation. It supplies qualified heating and hot water for the 600,000-ton/year styrene and other facilities and factory buildings, marking a revolutionary change in the company's winter heating and heat tracing heat sources. High-temperature heat pumps are devices that transfer heat from low-temperature heat sources to high-temperature heat sources through the circulation of refrigerants driven by electricity. They have the advantages of high efficiency, energy conservation, environmental protection, low carbon emissions, strong adaptability, and On December 14th, as the Qaidam Basin entered the severe cold season, the lowest temperature dropped to minus 15 degrees Celsius. The Qinghai Oilfield intensified its winter safety hazard inspection and governance. Through multi-dimensional approaches such as full participation in hazard inspection, professional supervision and verification, closed-loop rectification and elimination, and digital empowerment, a "safety protection net" was woven throughout the oilfield's oil and gas production areas. The Qinghai Oilfield closely focused on business areas such as crude oil production, natural gas supply guarantee, and engineering technical services. Guided by the requirements of the "Thunderbolt Action" for safe production and in combination with the winter safety risk preve As of December 3rd, Daqing Oilfield, the world's largest research and production base for tertiary oil recovery, has achieved a tertiary oil recovery output of over 10 million tons in 2025, maintaining an output of over 10 million tons for 24 consecutive years, with a cumulative output of 330 million tons, reaching a new peak in production. Tertiary oil recovery involves injecting chemical substances into oil layers to improve the performance of oil, gas, water, and rock interactions, thereby extracting more crude oil from rock pores. After several generations of hard work, Daqing Oilfield has developed its tertiary oil recovery technology from scratch, from following to leading, and has maintained a world-leading position. It has become the dominant development technology On November 28th, it was learned that the Da'an 1H28-4 well, located in the Linjiang syncline of the Da'an block in western Chongqing, was successfully drilled. With a single run of rotary steering achieving a total footage of 3,190 meters and a horizontal section of 2,575 meters, it not only set a new record for the longest horizontal section in the Da'an block but also established a new domestic record for the rotary steering single-run footage of deep shale gas horizontal wells. The 1H28-4 well, which reached a total depth of 6,915 meters, was drilled by the Daqing Drilling 70241 drilling team. Throughout the drilling process, the Exploration and Development Department of Zhejiang Oilfield fully played the leading role of the client, taking the "design, technology, too On November 24th, the "laser rust removal + automatic anti-corrosion" integrated pipeline production line independently developed by Tiancheng Lide Company of Huabei Oilfield was successfully put into operation and has been running stably. This production line adopts a seamless design of "rust removal - anti-corrosion", and through process integration and intelligent upgrading, it achieves clean and efficient production, promoting the "1+1>2" efficiency upgrade of pipeline business. To overcome the problems of high environmental risks, low efficiency, and unstable quality, Tiancheng Lide Company of Huabei Oilfield conducted on-site investigations at oilfield pipeline construction sites, construction units, and anti-corrosion manufacturers, systematically analyzed the l On November 12th, it was learned that a well at the shale oil fracturing site in the main oilfield area of Longdong in Changqing Oilfield successfully completed the carbon dioxide energy-enhanced fracturing operation and simultaneously achieved multiple integrated tests including casing external optical fiber monitoring, wellbore digital data collection, and dual-well microseismic monitoring under the high-temperature and high-pressure environment at a depth of 3,602 meters. Technical data shows that all indicators exceeded the design targets, and the implementation effect was significant. With this, the first domestic shale oil carbon dioxide energy-enhanced fracturing comprehensive monitoring test site has been officially established, marking an important breakthrough b As temperatures in Northeast China continue to drop, the pressure to ensure a steady supply of low pour point diesel has been increasing. Liaoyang Petrochemical has closely followed market demand changes, adjusted resource allocation, and optimized production plans to significantly increase the output of low pour point diesel. As of now, the daily average output of -35 diesel at Liaoyang Petrochemical has reached 2,000 tons, effectively meeting market demands. Facing the winter market demand, Liaoyang Petrochemical has ramped up production, making the increase of low pour point diesel a key focus of its current production organization. Through optimizing crude oil processing plans, finely adjusting operation parameters, and enhancing coordination among various facilities On November 3rd, at the well maintenance site of Well West 17-9 in the Downhole Operations Company of Dagang Oilfield, employees completed the operation tasks that previously required the cooperation of two positions by controlling the newly developed automatic pipe pusher device. Traditional minor well maintenance is a labor-intensive industry. On-site employees have been dealing with "iron blocks" such as hydraulic tongs, slips, and oil pipes for years, with high labor intensity and safety risks. During the daily process of raising and lowering oil pipes, well maintenance workers need to lift and lower oil pipes weighing over 100 kilograms onto and off the wellhead operation platform, which is time-consuming, laborious, and poses risks of collision and damage. Based on On October 28th, it was learned from Liaohe Oilfield that after the Shu 5 Combined Station of the oilfield adopted the new-generation low-temperature electric dehydration device, the water content of crude oil leaving the station was stably controlled within 0.3%, and the comprehensive cost per ton of liquid decreased by more than 20%. Dehydrating heavy oil has always been a difficult problem restricting the low-cost development of oilfields. The key and difficulty in achieving low-temperature dehydration lies in demulsification. The technical team of Liaohe Oilfield Design Institute deeply analyzed the physical and chemical properties of heavy oil emulsions, developed a multi-field coupling electric dehydration simulation experimental device, and systematically revealed On October 22nd, at the Laoyema Joint Station of the Oil and Gas Gathering and Transportation Company of Jidong Oilfield, employees used a newly developed carbonization cleaning device for filter cores to clean the filter cores. The cleaning process was both convenient and environmentally friendly. In the oil and gas gathering and transportation production system, the filter cores, which are the core components of the filters, are prone to being clogged by impurities such as crude oil resins, congealed oil, sand, flocs, and dead branches and weeds during use. The traditional manual cleaning method is inefficient, labor-intensive, and accelerates the wear of the filter cores, leading to frequent replacements and high costs. Facing this challenge, technicians actively carr On September 7th, the reporter learned from the Testing Technology Service Branch of Daqing Oilfield that its successfully developed wide area tracer logging technology has achieved a breakthrough in both accuracy and efficiency of reservoir water injection monitoring. This technology is the first of its kind in China and can effectively identify water absorbing layers with an injection depth of only 0.2 meters and a water injection volume of 0.3 cubic meters per day. The average efficiency of the test has been improved by 45%, and the average amount of isotope carrier used has been reduced by 83%, providing technical support for the fine development of oil fields. This technology innovatively develops the processes of "anti flocculation coating" and "surface active coating", wh As of now, the Internet of Things (IoT) online rate of the BaiKouQuan Oil Production Plant in Xinjiang Oilfield has remained stable at 98%, with data accuracy reaching 99% and equipment integrity rate maintained at 95%. The plant has shifted from merely "building well" to "managing well" and "utilizing well", laying a solid foundation for the digital and intelligent transformation of the oilfield. The BaiKouQuan Oil Production Plant has upgraded its technology to optimize its management model. In software development, it has added an electronic ledger system and dual-end editing functions, making data recording more accurate and maintenance more convenient, and enhancing the precision and efficiency of inspections. The plant has also moved all alarm settings and interlock As of September 10th, Dagang Oilfield has carried out differentiated water injection management in 40 key blocks, achieving a reduction in natural decline and an increase in oil production of over 30,000 tons during the stage. The natural decline rate has decreased by 1.7 percentage points compared to the same period last year, with significant results in tapping the remaining oil. Currently, Dagang Oilfield is in the ultra-high water cut stage. Long-term water injection has led to increasingly complex reservoir seepage patterns, with highly dispersed remaining oil, making precise characterization more difficult. To address this, researchers have relied on detailed reservoir description results to continuously enhance their understanding of reservoir potential, deeply an On August 25th, it was learned that the Gao166-77 well, drilled by the Fourth Drilling Company of Bohai Drilling, was successfully completed, setting new records for the shortest drilling cycle, the shortest drilling and completion cycle, and the fastest average mechanical drilling rate in the Jidong Oilfield. The Gao166-77 well is a directional well in the Gao66X1 block of the Gaoshanpu Oilfield in the northern part of the Gao Shen area of the Jidong Oilfield. It is located in a complex lithological area, facing multiple construction challenges such as the Guantao bottom conglomerate, black basalt, and large sections of brownish-red mudstone. Based on the high-quality completion of the Gao166-79 well in the early stage, the technicians of the Fourth Drilling Company cont Since the beginning of this year, Daqing Petrochemical Company has been adjusting the material flow in the oil refining area based on the principle of "oil when appropriate, olefin when appropriate, and aromatics when appropriate", optimizing the production of self-produced heavy ethylene feedstock, and achieving efficient operation of the oil refining area facilities. From January to July, the overall ethylene yield increased by 0.12% year-on-year, and the overall yield of ethylene and propylene increased by 0.13% year-on-year, demonstrating significant efficiency gains from the integrated layout of refining and chemical production. Systematically optimizing the structure and enhancing raw material quality. Faced with the dual challenges of blending finished oil and supp On August 5th, with the successful completion of a horizontal well at the Guping 41-52 well site, the number of wells in the Changqing Heshui Oilfield's tight oil block-level horizontal well three-dimensional development area exceeded 650, making it the largest such development area in China. Since its development, the area has produced over 5 million tons of oil, with a cumulative oil production 6.5 times that of the directional well development area. The production uptime of oil wells has increased by 17% year-on-year, marking a new development path for the efficient development of tight oil. The Changqing Heshui Oilfield in Longdong, Gansu Province, is a typical tight oil reservoir with rich resources. However, its poor reservoir properties and weak seepage capacity ha As of now, the Tuha Oilfield has completed 46 various plans for capacity construction and other aspects this year, with the design compliance rate reaching 100% and the effectiveness rate of measures reaching 98%. This has effectively saved drilling and fracturing costs, and the supporting and guaranteeing role of engineering technology has become more prominent. As the oilfield shifts to increasing reserves and production in ultra-deep and unconventional areas, the geological conditions have become more complex, posing higher requirements for engineering technical services. Since the beginning of this year, the engineering technical service units of the Tuha Oilfield have focused on key projects, accelerated technological innovation, and improved service quality. Engine On July 7th, the author learned that in the first half of this year, the commercial volume of coalbed methane in Huabei Oilfield increased by 45 million cubic meters compared with the same period last year. Huabei Oilfield has been committed to treating the coalbed methane business as an important growth pole for building a comprehensive energy company with a production capacity of 10 million tons of oil equivalent. Since the beginning of this year, Huabei Oilfield has followed the strategy of "developing Qingshui and expanding the periphery", empowered by both self-operation and cooperation, and focused on efficient production increase of coalbed methane, accelerating the construction of a green and intelligent industrial base with "one main and three auxiliary" function On May 21st, in the centralized control room of the refining area of Lanzhou Petrochemical, the internal line operators of the 5 million tons/year atmospheric and vacuum distillation unit were carefully comparing the quality inspection and analysis results. By swiping the mouse at the control points on the screen, they adjusted the external release volume of the atmospheric line again, precisely keeping the freezing point of the jet fuel above the quality index to ensure the maximization of the jet fuel yield. Since the beginning of this year, Lanzhou Petrochemical has been market-oriented, fully implementing the policy of "reducing fuel consumption and increasing navigation", achieving efficient coordination among production, sales and transportation, optimizing the stru It is reported that recently, it was learned from Changsha gas transmission branch of west east gas transmission of national pipe network that the company successfully completed the task of ensuring the supply of natural gas in Hunan Province in winter, and transported 1.625 billion cubic meters of natural gas to Hunan Province, a year-on- year increase of 9.26%.

The tightness of the regulating valve directly affects the performance and service life of the product, especially for some key industrial and mining enterprises. In addition to the debate, the international community is more important to support China's development. Especially since the epidemic, considering the actual di As my country's industrial development continues to deepen, the requirements for automation of electrical equipment in industrial production are getting higher and higher. The stable and long-term development of enterprises is inseparable from the support of advanced electrical automation instruments and automation control technology. The scale of industrial production continues to expand. The development of industrial electrical automation instrumentation is stable. The working principle of industrial automation instruments is to use intelligent methods to collect and monitor the information in the production process, which can help the production work to be completed more accurately. Inspection in the production process is a very important link for industrial production, and ind    With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i Recently, it was learned from the national pipe network group that the Zhangjiakou branch project of Shaanxi Beijing line 4 natural gas pipeline started construction on the 10th. After completion, the gas supply can cover all winter Olympic venues in Zhangjiakou. The total length of the project is 173.7 km, which is composed of 6 branch lines, 11 off load stations are set along the line, the designed annual gas transmission is 3.2 billion m3, and the total investment is 1.26 billion yuan. After the completion of the project, nearly 9 million cubic meters of natural gas can be transported to Zhangjiakou every day, benefiting about 220000 families in Zhangjiakou and realizing the "county to county connection" of natural gas in Zhangjiakou. The relevant person in charge As an important part of my country's manufacturing industry, the instrument and meter manufacturing industry has played an important role in promoting the country's economic growth and social development. With the continuous development of social economy and technology, my country's instrumentation industry has been advancing all the way in recent years. How much do you know about instrumentation! Instruments and meters are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In detail, instruments and meters have functions such as automatic control, alarm, sig The automatic adjustment system of the industrial production process is generally composed of a detector, a regulating valve, an actuator and an adjustment object, and the actuator is an indispensable and important part of it. As the terminal product in the industrial process control system, it plays an irreplaceable role for other products in the automatic control system. From the perspective of the industry, the development speed of the implementation of electric control valves in my country lags behind other control instruments. However, this phenomenon is being changed. Not long ago, China Machinery Industry Federation and China General Machinery Industry Association held a product appraisal of "Hydraulic Actuator for Tank Root Valve and Electro-hydraulic Actu The green development of industry needs innovation. Without innovation, the industry will not progress, and the goal of enterprise development will be difficult to achieve. Green development is not only the need of ecological civilization construction, but also the need of China's development in the new era. The high-quality development of social economy and the improvement of the quality of people's living environment must depend on the industrial progress. If the industrial production mode is relatively backward, such as the problem of dripping and running in the production process, it will produce relatively serious pollution problems, and the development goals of clean production and green industry can not be achieved. In the pharmaceutical industry, if the performance of the Because the tank wall manhole is located in the lower part of the oil tank, the manhole bears a lot of liquid pressure. In order to prevent leakage, the installation quality of the manhole must be strictly required. The flanges and cover plates are processed with sealing water lines, and care should be taken to protect them during construction to avoid oil leakage during use. Make a mark every time the manhole is removed, so as to avoid dislocation during reinstallation and affect the tightness. When installing the nuts on the manhole cover, apply force evenly in pairs to prevent oil leakage caused by deformation of the cover or uneven force. The tank wall manhole is installed in the lower part of the storage tank, and is mainly used for the staff to enter and exit the storage tan It is reported that the 2021 China International Fluid Machinery Exhibition, which is highly anticipated by the industry, has successfully closed in Shanghai Hongqiao National Convention and Exhibition Center.

On January 23, the author learned that the Jilantai Oilfield of the Bayan Branch of Huabei Oilfield has continuously deepened the efficient development management model of old oilfields, constantly optimized the technical system and management mechanism, and all key development indicators are at the leading level in the industry. In 2025, the Jilantai Oilfield was awarded the title of "Efficient Development Oilfield" in the oil and gas new energy sector of the Group Company. In 2025, facing multiple challenges such as complex geological conditions, limitations of conventional development technologies, and high difficulty in efficient development, the Jilantai Oilfield innovatively adopted the development methods of "metamorphic rock basement volume fracturing + bottom wat On January 21st, the Wunan 3-2-13X well of the Tarim Oilfield was officially put into operation. This well successfully completed the lowering of the retrievable electric pump and achieved a qualified trial pumping within the middle of this month. It realized the application of the retrievable electric pump lifting technology at a depth of 2500 meters, providing a new technical approach for the Tarim Oilfield to cope with complex working conditions, significantly reducing maintenance and inspection costs, and improving efficiency. Electric pump lifting is an important artificial lifting method in oilfield crude oil production. As the oil and gas development in the Tarim Oilfield continues, electric pump wells generally face complex production environments such as asphalti On January 5th, a reporter learned from the Oil and Gas Technology Research Institute of Jilin Oilfield that the Jilin Oilfield's intensive overall fracturing technology has focused on the capacity building of conventional oil, precisely exerting its technical support role, and achieving a new breakthrough in the capacity building of old oilfields. Up to now, the Jilin Oilfield has applied this technology to conduct fracturing operations on 448 wells in a year, with a success rate of 98%. The average daily oil production per well has increased by 21% compared to the design, and the project's conversion rate has reached 100%. The secondary development of the low-permeability old oilfields in Jilin Oilfield faces multiple challenges such as complex injection-production patt On December 22, the author learned that the high-temperature heat pump system of the third thermal station, a key supporting project for the western transformation and upgrading of Jilin Petrochemical, was successfully put into operation. It supplies qualified heating and hot water for the 600,000-ton/year styrene and other facilities and factory buildings, marking a revolutionary change in the company's winter heating and heat tracing heat sources. High-temperature heat pumps are devices that transfer heat from low-temperature heat sources to high-temperature heat sources through the circulation of refrigerants driven by electricity. They have the advantages of high efficiency, energy conservation, environmental protection, low carbon emissions, strong adaptability, and On December 14th, as the Qaidam Basin entered the severe cold season, the lowest temperature dropped to minus 15 degrees Celsius. The Qinghai Oilfield intensified its winter safety hazard inspection and governance. Through multi-dimensional approaches such as full participation in hazard inspection, professional supervision and verification, closed-loop rectification and elimination, and digital empowerment, a "safety protection net" was woven throughout the oilfield's oil and gas production areas. The Qinghai Oilfield closely focused on business areas such as crude oil production, natural gas supply guarantee, and engineering technical services. Guided by the requirements of the "Thunderbolt Action" for safe production and in combination with the winter safety risk preve As of December 3rd, Daqing Oilfield, the world's largest research and production base for tertiary oil recovery, has achieved a tertiary oil recovery output of over 10 million tons in 2025, maintaining an output of over 10 million tons for 24 consecutive years, with a cumulative output of 330 million tons, reaching a new peak in production. Tertiary oil recovery involves injecting chemical substances into oil layers to improve the performance of oil, gas, water, and rock interactions, thereby extracting more crude oil from rock pores. After several generations of hard work, Daqing Oilfield has developed its tertiary oil recovery technology from scratch, from following to leading, and has maintained a world-leading position. It has become the dominant development technology On November 28th, it was learned that the Da'an 1H28-4 well, located in the Linjiang syncline of the Da'an block in western Chongqing, was successfully drilled. With a single run of rotary steering achieving a total footage of 3,190 meters and a horizontal section of 2,575 meters, it not only set a new record for the longest horizontal section in the Da'an block but also established a new domestic record for the rotary steering single-run footage of deep shale gas horizontal wells. The 1H28-4 well, which reached a total depth of 6,915 meters, was drilled by the Daqing Drilling 70241 drilling team. Throughout the drilling process, the Exploration and Development Department of Zhejiang Oilfield fully played the leading role of the client, taking the "design, technology, too On November 24th, the "laser rust removal + automatic anti-corrosion" integrated pipeline production line independently developed by Tiancheng Lide Company of Huabei Oilfield was successfully put into operation and has been running stably. This production line adopts a seamless design of "rust removal - anti-corrosion", and through process integration and intelligent upgrading, it achieves clean and efficient production, promoting the "1+1>2" efficiency upgrade of pipeline business. To overcome the problems of high environmental risks, low efficiency, and unstable quality, Tiancheng Lide Company of Huabei Oilfield conducted on-site investigations at oilfield pipeline construction sites, construction units, and anti-corrosion manufacturers, systematically analyzed the l On November 12th, it was learned that a well at the shale oil fracturing site in the main oilfield area of Longdong in Changqing Oilfield successfully completed the carbon dioxide energy-enhanced fracturing operation and simultaneously achieved multiple integrated tests including casing external optical fiber monitoring, wellbore digital data collection, and dual-well microseismic monitoring under the high-temperature and high-pressure environment at a depth of 3,602 meters. Technical data shows that all indicators exceeded the design targets, and the implementation effect was significant. With this, the first domestic shale oil carbon dioxide energy-enhanced fracturing comprehensive monitoring test site has been officially established, marking an important breakthrough b As temperatures in Northeast China continue to drop, the pressure to ensure a steady supply of low pour point diesel has been increasing. Liaoyang Petrochemical has closely followed market demand changes, adjusted resource allocation, and optimized production plans to significantly increase the output of low pour point diesel. As of now, the daily average output of -35 diesel at Liaoyang Petrochemical has reached 2,000 tons, effectively meeting market demands. Facing the winter market demand, Liaoyang Petrochemical has ramped up production, making the increase of low pour point diesel a key focus of its current production organization. Through optimizing crude oil processing plans, finely adjusting operation parameters, and enhancing coordination among various facilities On November 3rd, at the well maintenance site of Well West 17-9 in the Downhole Operations Company of Dagang Oilfield, employees completed the operation tasks that previously required the cooperation of two positions by controlling the newly developed automatic pipe pusher device. Traditional minor well maintenance is a labor-intensive industry. On-site employees have been dealing with "iron blocks" such as hydraulic tongs, slips, and oil pipes for years, with high labor intensity and safety risks. During the daily process of raising and lowering oil pipes, well maintenance workers need to lift and lower oil pipes weighing over 100 kilograms onto and off the wellhead operation platform, which is time-consuming, laborious, and poses risks of collision and damage. Based on On October 28th, it was learned from Liaohe Oilfield that after the Shu 5 Combined Station of the oilfield adopted the new-generation low-temperature electric dehydration device, the water content of crude oil leaving the station was stably controlled within 0.3%, and the comprehensive cost per ton of liquid decreased by more than 20%. Dehydrating heavy oil has always been a difficult problem restricting the low-cost development of oilfields. The key and difficulty in achieving low-temperature dehydration lies in demulsification. The technical team of Liaohe Oilfield Design Institute deeply analyzed the physical and chemical properties of heavy oil emulsions, developed a multi-field coupling electric dehydration simulation experimental device, and systematically revealed On October 22nd, at the Laoyema Joint Station of the Oil and Gas Gathering and Transportation Company of Jidong Oilfield, employees used a newly developed carbonization cleaning device for filter cores to clean the filter cores. The cleaning process was both convenient and environmentally friendly. In the oil and gas gathering and transportation production system, the filter cores, which are the core components of the filters, are prone to being clogged by impurities such as crude oil resins, congealed oil, sand, flocs, and dead branches and weeds during use. The traditional manual cleaning method is inefficient, labor-intensive, and accelerates the wear of the filter cores, leading to frequent replacements and high costs. Facing this challenge, technicians actively carr On September 7th, the reporter learned from the Testing Technology Service Branch of Daqing Oilfield that its successfully developed wide area tracer logging technology has achieved a breakthrough in both accuracy and efficiency of reservoir water injection monitoring. This technology is the first of its kind in China and can effectively identify water absorbing layers with an injection depth of only 0.2 meters and a water injection volume of 0.3 cubic meters per day. The average efficiency of the test has been improved by 45%, and the average amount of isotope carrier used has been reduced by 83%, providing technical support for the fine development of oil fields. This technology innovatively develops the processes of "anti flocculation coating" and "surface active coating", wh As of now, the Internet of Things (IoT) online rate of the BaiKouQuan Oil Production Plant in Xinjiang Oilfield has remained stable at 98%, with data accuracy reaching 99% and equipment integrity rate maintained at 95%. The plant has shifted from merely "building well" to "managing well" and "utilizing well", laying a solid foundation for the digital and intelligent transformation of the oilfield. The BaiKouQuan Oil Production Plant has upgraded its technology to optimize its management model. In software development, it has added an electronic ledger system and dual-end editing functions, making data recording more accurate and maintenance more convenient, and enhancing the precision and efficiency of inspections. The plant has also moved all alarm settings and interlock As of September 10th, Dagang Oilfield has carried out differentiated water injection management in 40 key blocks, achieving a reduction in natural decline and an increase in oil production of over 30,000 tons during the stage. The natural decline rate has decreased by 1.7 percentage points compared to the same period last year, with significant results in tapping the remaining oil. Currently, Dagang Oilfield is in the ultra-high water cut stage. Long-term water injection has led to increasingly complex reservoir seepage patterns, with highly dispersed remaining oil, making precise characterization more difficult. To address this, researchers have relied on detailed reservoir description results to continuously enhance their understanding of reservoir potential, deeply an On August 25th, it was learned that the Gao166-77 well, drilled by the Fourth Drilling Company of Bohai Drilling, was successfully completed, setting new records for the shortest drilling cycle, the shortest drilling and completion cycle, and the fastest average mechanical drilling rate in the Jidong Oilfield. The Gao166-77 well is a directional well in the Gao66X1 block of the Gaoshanpu Oilfield in the northern part of the Gao Shen area of the Jidong Oilfield. It is located in a complex lithological area, facing multiple construction challenges such as the Guantao bottom conglomerate, black basalt, and large sections of brownish-red mudstone. Based on the high-quality completion of the Gao166-79 well in the early stage, the technicians of the Fourth Drilling Company cont Since the beginning of this year, Daqing Petrochemical Company has been adjusting the material flow in the oil refining area based on the principle of "oil when appropriate, olefin when appropriate, and aromatics when appropriate", optimizing the production of self-produced heavy ethylene feedstock, and achieving efficient operation of the oil refining area facilities. From January to July, the overall ethylene yield increased by 0.12% year-on-year, and the overall yield of ethylene and propylene increased by 0.13% year-on-year, demonstrating significant efficiency gains from the integrated layout of refining and chemical production. Systematically optimizing the structure and enhancing raw material quality. Faced with the dual challenges of blending finished oil and supp On August 5th, with the successful completion of a horizontal well at the Guping 41-52 well site, the number of wells in the Changqing Heshui Oilfield's tight oil block-level horizontal well three-dimensional development area exceeded 650, making it the largest such development area in China. Since its development, the area has produced over 5 million tons of oil, with a cumulative oil production 6.5 times that of the directional well development area. The production uptime of oil wells has increased by 17% year-on-year, marking a new development path for the efficient development of tight oil. The Changqing Heshui Oilfield in Longdong, Gansu Province, is a typical tight oil reservoir with rich resources. However, its poor reservoir properties and weak seepage capacity ha As of now, the Tuha Oilfield has completed 46 various plans for capacity construction and other aspects this year, with the design compliance rate reaching 100% and the effectiveness rate of measures reaching 98%. This has effectively saved drilling and fracturing costs, and the supporting and guaranteeing role of engineering technology has become more prominent. As the oilfield shifts to increasing reserves and production in ultra-deep and unconventional areas, the geological conditions have become more complex, posing higher requirements for engineering technical services. Since the beginning of this year, the engineering technical service units of the Tuha Oilfield have focused on key projects, accelerated technological innovation, and improved service quality. Engine On July 7th, the author learned that in the first half of this year, the commercial volume of coalbed methane in Huabei Oilfield increased by 45 million cubic meters compared with the same period last year. Huabei Oilfield has been committed to treating the coalbed methane business as an important growth pole for building a comprehensive energy company with a production capacity of 10 million tons of oil equivalent. Since the beginning of this year, Huabei Oilfield has followed the strategy of "developing Qingshui and expanding the periphery", empowered by both self-operation and cooperation, and focused on efficient production increase of coalbed methane, accelerating the construction of a green and intelligent industrial base with "one main and three auxiliary" function On May 21st, in the centralized control room of the refining area of Lanzhou Petrochemical, the internal line operators of the 5 million tons/year atmospheric and vacuum distillation unit were carefully comparing the quality inspection and analysis results. By swiping the mouse at the control points on the screen, they adjusted the external release volume of the atmospheric line again, precisely keeping the freezing point of the jet fuel above the quality index to ensure the maximization of the jet fuel yield. Since the beginning of this year, Lanzhou Petrochemical has been market-oriented, fully implementing the policy of "reducing fuel consumption and increasing navigation", achieving efficient coordination among production, sales and transportation, optimizing the stru It is reported that recently, it was learned from Changsha gas transmission branch of west east gas transmission of national pipe network that the company successfully completed the task of ensuring the supply of natural gas in Hunan Province in winter, and transported 1.625 billion cubic meters of natural gas to Hunan Province, a year-on- year increase of 9.26%.

The report of the 19th National Congress of the Communist Party of China proposed to "give greater reform autonomy to the free trade pilot zone and explore the construction of free trade ports", and domestic ports, large and small, responded one after another. Zhoushan Port, Tianjin Port and Huizhou Port, as coastal oil ports in the Yangtze River Delta Economic Circle, the Bohai Economic Circle and the Pearl River Delta Economic Circle, play the leading role of the Shanghai Futures Exchange in the oil and gas trade and financial market, and lead the surrounding ports to continuously explore suitable ports for themselves. The oil and gas development path has made the domestic port oi At present, green and low carbon has become the consensus of the mainstream society in the world. The Chinese government has committed to strive to achieve carbon peaking by 2030 and carbon neutrality by 2060. To this end, while vigorously developing non-fossil energy, "removing coal and reducing oil" and gradually reducing the share and quantity of natural gas in energy consumption have become the main theme of the future development of the energy sector. In the context of "dual carbon", the concept of "green finance" is heating up. Some people propose to significantly reduce investment in fossil energy and require financial institutions to stop providing loans for it. The argument that oil and gas is a "sunset industry" has resurfaced. But the completion of the energy tran Water conservancy projects are not only important basic projects, but also important livelihood projects. In the construction of various water conservancy projects, the pressure reducing valve is naturally inseparable. The pressure reducing valve plays an important role in the construction of water pipelines, hydroelectric gates and water pump projects. In the construction of water conservancy projects, if the performance of the pressure reducing valve is not ideal, it may affect the normal delivery and use of the water conservancy project. To create high-standard water conservancy projects, high-quality pressure reducing valves must be guaranteed. The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjus Now our country’s environmental problems are very serious, causing great harm to our lives and production. Government departments have been vigorously rectifying, and constantly promulgating various policies for governance. Under this severe situation, the environmental protection valve industry has also developed very well. Urban sewage treatment equipment has greatly promoted the production and sales of environmentally friendly valves. The water pollution in our country is very serious. Both the ground and groundwater are very polluted. my country's sewage treatment technology is still relatively rudimentary, and the pollution level is far greater than the sewage treatment effect. Now we have realized the seriousness of environmental pollution. The treatment of domestic sewage a It is reported that recently, the LNG filling station and LNG container terminal project of Anhui Wuhu Yangtze River LNG inland receiving (transfer) station project, which is generally contracted by CCCC Second Harbor Institute and participated by CCCC Second Harbor Bureau, has been completed and put into operation.
