Five 100-ton blocks including Shen 273 were built in the oil field, and the replacement pattern of stable production was fully optimized. Natural gas production reached a new high in the past 17 years.
Continue to stabilize production and be driven by innovation. Liaohe Oilfield coordinates "supporting the present" and "leading the future", taking into account both "rapid breakthroughs" and "long-term success", deepens the project of strengthening the enterprise through talents, improves the scientific research system and mechanism, and promotes self-reliance and self-reliance in science and technology. The majority of scientific researchers have firmly focused on the main direction of research and continued to strengthen basic research. A number of key core technologies have achieved breakthroughs, and the supporting role of scientific and technological innovation has been further highlighted. In the past three years, 28 scientific and technological achievements at or above the provincial and ministerial levels have been achieved. Independently developed intelligent injection-production linkage technology to assist water injection development with stable oil and water control; the country's first electromechanical integrated pipe scraping and sand fishing technology, reducing test well operating costs by 40%; successfully tackled the multi-field coupled heavy oil closed dehydration process, processing The viscosity of crude oil has increased nearly five times compared to the recommended value in the specification; the mobile downhole high-power electric heating technology has been shortlisted for the "World Petroleum Award" finals. The digital coverage of oilfield wells and stations has increased to 65% and 66% respectively, and substantial progress has been made in the application of digital technology.
A new journey calls for a new atmosphere. The Party Committee of Liaohe Oilfield Company implemented the work deployment of Liaoning Province and identified 2024 as a critical year for the development of the company. In order to show greater responsibility in ensuring energy supply and creating value in the old oil fields, it carried out a deeper strategic plan: Committed to ensuring energy supply. supply, plan to build "three strategic bases"; commit to value creation, and systematically promote "five ways of transformation".

After ten years of hard work, the Liaohe gas storage group leads the country
As the "backbone" of ensuring energy supply, natural gas is an important position and a new battlefield for Liaohe Oilfield. Liaohe Oilfield resolutely shouldered the new mission of peak shaving and ensuring supply of natural gas, continuously broke through technical problems such as natural gas storage, and accelerated the construction of a "10-billion-square-meter gas storage" with overall efforts.
From the start of construction in 2011, Shuang 6, Shuangtaizi, Lei 61 and other gas storages have been included in the list; from the first external gas supply in 2016 to the successful completion of the eighth round of gas production cycle on March 17 this year, the Liaohe gas storage group As an important hub on the national energy artery, it has been included in the national "14th Five-Year Plan" key projects. Its daily gas injection and peaking capacity have reached 48.1 million cubic meters and 41 million cubic meters respectively, maintaining the leading position in the country. The cumulative gas production has exceeded 13 billion cubic meters. . In the eighth round of gas production cycle that just ended, the Liaohe gas storage group became the first gas storage in the country to have cycle gas production exceeding 3 billion cubic meters, and the highest single-day peak gas production exceeding 40 million cubic meters. It is the gas storage with the longest supply time, and ranks first in the country in terms of guaranteed gas supply volume on a periodic basis and on a single day.
In recent years, Liaohe Oilfield has insisted on synchronously advancing peak shaving and ensuring supply and construction and operation, and the underground "gas warehouse" has become larger and larger. The pilot test project of the Ma-19 gas storage, which was newly put into operation last year, took only 7 and a half months from start to completion, setting another record for the fastest gas storage construction in the country. During the construction process, Liaohe Oilfield researchers bravely challenged themselves, broke through themselves, conducted in-depth research on the geological characteristics of oil and gas reservoir development, and innovatively proposed a reservoir construction method of "ring gas injection in new wells at the top, staged drainage of old wells in the middle and lower parts, and gradually forming an effective gas cap" This method pioneered the construction of water-flooded oil and gas reservoirs in China and provided theoretical and practical support for the construction of similar types of gas storages.
In addition, Liaohe Oilfield built three large-sized wells to achieve "large-scale throughput", creating the shortest record of 90 days for the domestic gas storage large-scale drilling project. The gas injection and production capacity is three times that of conventional wells, and the daily increase is The peak shaving capacity is more than 3 million cubic meters, helping Liaohe River lead the country in peak shaving capacity.

Make multiple breakthroughs in transformation and upgrading to build a new pattern of green development
As the "backbone" of ensuring energy supply, expanding green areas and reducing carbon emissions is the only way to go. Based on the new development stage, the cadres and employees of Liaohe Oilfield have firmly established the concept of "grasping new energy as well as oil and gas production" and firmly promoted green and low-carbon transformation and development. The company's leaders and the backbone of each system formed a special new energy class to develop the clean energy business with unprecedented intensity and implement the "Green and Low Carbon 613 Project". At the same time, carbon storage, energy storage and gas storage will be developed simultaneously to accelerate the "three major projects" in Liaohe. "Reservoir" construction, comprehensively build a strategic base for green transformation and upgrading, and multi-energy integration development, and strive to contribute to the realization of the "double carbon" goal in the surrounding areas.
Bravely pursue a new green and low-carbon path. After hard work, Liaohe Oilfield built and put into operation the world's first electrothermal molten salt energy storage and steam injection test station, and completed the world's first 1MW underground high-power electric heating technology. Among them, the new steam injection station applies molten salt energy storage technology to heavy oil gas injection development for the first time. It not only explores a new path for clean energy substitution in oil fields, but also has the function of consuming green electricity and regulating the power grid. Downhole high-power electric heating technology breaks through seven major technical bottlenecks, including high temperature, high voltage, and long-term insulation of small-sized devices, and increases the heating power to 1 megawatt, helping the heavy oil thermal recovery process to "replace gas with electricity, improve efficiency and production, Carbon reduction and emission reduction”.
The green and low-carbon industry of Liaohe Oilfield has embarked on the fast track of large-scale development. Distributed photovoltaic projects cover more than a thousand well sites, with a grid-connected installed capacity of 100 megawatts and clean power generation exceeding 100 million kWh. The CCUS project has been included in the Liaoning Province "Revelation List and Leading" project, and has put into operation the joyful extraction, special oil capture station and double 229 circulation injection station. The scale of carbon injection and oil production is at the forefront of China's petroleum pilot tests. The "Energy Efficiency Leader" action was implemented to slim down and improve the old oil fields. In 2023, measures were taken to save 73,000 tons of standard coal and 348,000 cubic meters of water. The oil field won the national "People's Corporate Social Responsibility Award (Green Development Award)".
At the same time, Liaohe Oilfield conscientiously implements the spirit of the high-level consultation between PetroChina and Liaoning Province, gives full play to the leading role of CNPC's enterprises in Liaoning in the development and construction of supporting clean power, and leads seven enterprises in Liaoning to jointly promote the coordinated development of "refining + new energy".
