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

Since the beginning of the year, Daqing Drilling Company has focused on the "Hundred-Billion-Yuan Output and Efficiency Enhancement Project", launching five major battles: transforming concepts, deepening reforms, marketing, strengthening the enterprise, and improving management. In the first quarter of this year, the company's cumulative number of completed wells and footage increased by 12.4% and 14.3% respectively compared to the same period last year. Facing complex situations such as deep, non-conventional, and old fields, Daqing Drilling has promoted engineering and technical service cooperation models such as "integration of the client and contractor, integration of geology and engineering, integration of investment and cost, and integration of construction, produc On March 23, it was learned from Jinxi Petrochemical that since the water heating transformation project of the Dongyoupin facility's Liaohe tank farm was put into operation one and a half months ago, it has saved over 3,700 tons of steam and achieved energy-saving benefits of more than 650,000 yuan, marking a solid step forward for the company in its green and low-carbon transformation. Previously, Jinxi Petrochemical had completed the water heating transformation of the heavy oil catalytic unit, accumulating transformation experience. This time, the water heating transformation of the Dongyoupin facility's Liaohe tank farm was implemented based on the existing Xifang heat medium water system, taking into account both energy-saving benefits and production safety. It adop On March 24th, at the construction sites of the 1 million kilowatt wind power project in Turpan Shanshan and the 1 million kilowatt photovoltaic project in Shanshan East of the Tuha Oilfield, machines were roaring and workers were operating in an orderly manner. The construction of the two 1 million kilowatt new energy projects of the Tuha Oilfield has entered a fast lane. Turpan is known as the "Wind Repository" and "China's Hottest Place", with natural conditions suitable for the development of wind power and photovoltaic power. The "Thirty Mile Wind Area" in Xiaocaohu has abundant wind resources throughout the year, with an average annual wind speed of over 8 meters per second and extreme gusts reaching up to level 14. It also has abundant sunlight, with over 3,200 hou Lanzhou Petrochemical Company has successfully solved the problem of processing high-sulfur crude oil by means of precise scientific "formulas", providing support for improving resource processing efficiency and optimizing raw material structure. As of March 3rd, the company has processed a total of 318,000 tons of Kazakh and Bayan crude oil this year, achieving clean and efficient conversion of low-quality crude oil and laying a solid foundation for the entire year's production. In February, Kazakh crude oil accounted for 42% of the crude oil entering Lanzhou Petrochemical. However, Kazakh crude oil has a high sulfur content and strong corrosiveness, which increases the risk of equipment corrosion and poses new challenges to processing and blending. In response to these On March 5th, at the site of Well Wawa 38-39-K033CH in Jinhai Oil Production Plant of Liaohe Oilfield, after the application of the gravel packing technology, the well successfully overcame the long-term sand production problem and achieved a stable daily oil production of 2.2 tons. This marks the first successful application of the "small wellbore dedicated tubing + top packing" integrated technology in this type of well, filling the gap in efficient sand control technology for small wellbore horizontal wells in Liaohe Oilfield. Previously, Well Wawa 38-39-K033CH, with its typical small wellbore specification of 5-inch casing, faced technical challenges such as high packing friction and small annular gap in the horizontal section, making it difficult for conventional tec Just after the Spring Festival, good news came from the production frontline of Changqing Oilfield: As of February 21, the oil and gas production equivalent of Changqing Oilfield in 2026 had rapidly surpassed the 10 million-ton mark, demonstrating a strong start to the "15th Five-Year Plan" period. This impressive performance sheet is a direct reflection of Changqing Oilfield's efforts in maintaining stable production from old wells and increasing output from new ones, marking the significant effectiveness of its measures for high-level production and stable growth.
