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.

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

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.

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.
