As of May 15, the first batch of group energy-storing fracturing wells at Xinjiang Oilfield's First Production Plant (Hongshan Company) have shown impressive production performance after being put into operation. Among them, five wells are producing by natural flow, with a daily incremental oil production of 15 tons across the well group and an average daily increase of 1.7 tons per well. The Keshang Formation reservoir in the Hong60 well area of the First Production Plant is a lithology-controlled structural reservoir, representing a typical medium-porosity, ultra-low-permeability reservoir with complex geological conditions. The block contains 29 oil and water wells, but due to a large well spacing of 350 meters, water flooding efficiency has been poor. Conventional fra On May 21, reporters learned that the first wind turbine of the Renqiu 150,000-kilowatt wind power project in North China Oilfield has been successfully installed, demonstrating strong momentum in new energy development. Additionally, both oil and gas reserves and production at North China Oilfield have surpassed the same period last year. Traditional and emerging industries are working synergistically to continuously strengthen the energy supply foundation for mature eastern oilfields. Focusing on building a new energy system, North China Oilfield treats reserve-production balance as the lifeline for sustainable oil and gas development, consistently transforming its development model by steadily increasing reserves and output while enhancing the value creation capacity o       “吸附塔压力平稳，进料组分波动在可控范围内，这次优化方案见效了。”5月18日，在辽阳石化芳烃联合装置控制室，当班操作工实时反馈参数。前4个月，该公司通过调整物料流转方向，对二甲苯装置累计产量同比增长4.1%，刷新了近5年的最高纪录，提质增效攻坚取得重要突破。       今年年初以来，辽阳石化面对混合二甲苯原料短缺的挑战，牢固树立“大平稳产生大效益”理念，在不改变原有运行模式的前提下，紧盯原料指标变化，精准调控关键参数，加强全流程效益测算，持续提升对二甲苯收率与装置运行效率。技术人员强化全流程精细管控，落实关键机组特护与异常管理，确保装置在高负荷工况下保持稳产高产的良好态势。同时，通过开展红旗班组评比活动、优化操作流程等措施，充分激发一线员工积极性，着力解决影响长周期运行的关键问题，推动各项生产指标持续向好。 On May 6, it was learned that Xinghua 12-44X well—the core production well of the CCUS-EOR pilot test at Bayan Oilfield in North China Oilfield—successfully completed its fluid profile logging operation. This marks a significant breakthrough in conventional fluid profile logging for high-paraffin self-flowing oil wells at North China Oilfield. A fluid profile refers to the precise measurement of the proportions and flow rates of oil, water, and carbon dioxide produced from each perforated interval along the vertical depth of an oil and gas well. It enables identification of main producing zones, underutilized layers, gas-producing zones, and water-bearing zones, as well as assessment of CO₂ distribution, migration direction, and breakthrough locations within the wel As of May 17, after applying CCUS-EOR (carbon dioxide capture, utilization and storage-enhanced oil recovery) technology in the Niuquanhu East area of Santanghu Oilfield, Turpan-Hami Oilfield has achieved cumulative oil production increase exceeding 20,000 tons in the pilot block, with a recovery factor improved by 1.4%, effectively doubling production in the test area. Turpan-Hami Oilfield features diverse and complex reservoir types. As development progresses, conventional reservoirs in mature areas exhibit high water content, while new areas primarily rely on unconventional production, leading to rapid production decline. Therefore, effective methods for enhancing recovery are urgently needed. After years of research and breakthroughs, the oilfield has successively ove Since the beginning of this year, East China Chemical Sales has been steadily advancing its marketing breakthrough initiative amid a complex and ever-changing market environment. As of May 25, the company had cumulatively sold 20,000 tons of ethylene-propylene rubber products, marking a year-on-year increase of 116.91% and setting a new historical record. Achieving growth in both volume and quality, core products have realized large-scale breakthroughs. East China Chemical Sales continues to deepen its integrated "production-sales-research-application" collaboration model, actively promoting high-end product adoption and expanding application scenarios.

This accounts for 30% of the total daily crude oil production of North China Oilfield, and the SEC reserve-to-production ratio remains stable and favorable, achieving simultaneous growth in both volume and efficiency. Since the beginning of this year, Bayan Oilfield has adhered to the principle of "identifying reserves with production potential, building productive capacity, and securing profitable output." Relying on integrated evaluation involving exploration and development, geological engineering, and technical economics, the field has prioritized high-return blo On May 18, construction workers were carrying out orderly operations at the site of Lanzhou Petrochemical's new 110 tons/hour sour water stripping unit project.   For a long time, Lanzhou Petrochemical’s existing two sour water stripping units have had to operate at 120% capacity just to barely maintain a "tense balance" in handling sour water from the refining area. Project manager Gao Yunpeng said that with increasingly stringent national environmental regulations and the implementation of new facility plans, total sour water volume is expected to exceed 370 tons per hour, making current processing capacity insufficient to support production optimization and future development.   Once completed, the new unit will increase total sour water t On May 11, it was learned from the Tarim Oilfield that the Keshen 41 well was officially put into production, with 300,000 cubic meters of natural gas produced daily and fed into the West-East Gas Pipeline. The well has a total depth of 8,473 meters upon completion, setting new records for the deepest burial depth and the highest oil pressure in the Kela Su salt-bearing gas reservoir. This adds another "deep well warrior" to the main gas source area of the West-East Gas Pipeline. The Keshen 41 well is located in Baicheng County, Xinjiang. It is a key pre-exploration well aimed at the ultra-deep layer and the search for replacement resources in the main gas supply area of the West-East Gas Pipeline by the Tarim Oilfield. The well encountered good oil and gas indications in On May 5th, it was learned from Jilin Oilfield that the high-temperature resistant and high-strength water-absorbing swelling particle plugging agent developed by the Oil and Gas Technology Research Institute of the oilfield completed its first pilot test in the Yitong 45-2-6 well group. The test block showed a favorable development trend with a decline in liquid production, an increase in oil production, and a reduction in water cut. The water channeling control effect was remarkable. At the beginning of this year, the high-temperature resistant and high-strength water-absorbing swelling particle plugging agent entered the field test stage. Laboratory data indicated that the plugging agent could stably maintain its performance for 14 months at a temperature of 95 degrees On April 20th, 72 sets of camp houses, the first batch of products exported by Huabei Oilfield to Turkey, were successfully delivered by sea. These high-quality products, which meet the environmental protection standards of the European Union, are actively integrating into the global energy industry chain.

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
