As of the end of October, a total of 55 drilling and evaluation wells had been completed in Jilin Oilfield, with a cumulative depth of 180,600 meters and a three-dimensional seismic area of 750 square kilometers, which exceeded the planned workload for the whole year two months in advance.

Since this year, Jilin Oilfield has highlighted its position as a “leader” in exploration. Focusing on the core tasks of high-efficiency well positions and economically recoverable reserves, it has carved and refined, and made every effort to promote three-dimensional exploration in Southern Sichuan, fine exploration in Songnan, and risk exploration in new areas and new areas. Important discoveries have been made in a number of exploration fields, and various task indicators have been exceeded ahead of schedule.

Optimize and optimize to improve storage efficiency.Highlight the optimization of queuing and optimize the deployment plan of the efficiency-increasing storage area belt.We have increased the exploration of natural gas in Southern Sichuan, completed the three-dimensional collection of 600 square kilometers, and completed the drilling and evaluation of 14 wells. Important progress has been made in both conventional gas and shale gas. The strategic layout of “both normal and non-equal, three-dimensional exploration” has been initially realized, which provides strong support for Southern Sichuan to realize the benefits of natural gas at an early date and increase storage and production.Among them, important breakthroughs have been made in conventional gas. The six exploration wells that have been drilled have all seen good results, and the gas tests of the four exploration wells have been completed, and all have obtained high-yield airflow.Benefit construction and production resources are further consolidated.Vigorously implement the integration of exploration and development, and accelerate the implementation of shale gas efficiency and production resources.Increase the intensity of conventional oil exploration, fine exploration of oil-rich areas, and implement economic recoverability of more than one million tons.Breaking the original understanding of tectonic control of tibet in the old district of Fuyu, the “one sand, one tibet” enrichment model has been innovatively formed, with a new production capacity of 10,000 tons.

Dig deep into the potential and implement the benefit block.Deepen geological understanding, follow the principle of vertical search for new layers, strengthen the re-evaluation of old wells, and ask for reserves, production, and benefits from old wells.A total of more than 3,600 old wells have been reviewed, and 225 potential wells have been implemented; 33 old wells have been tested for oil, and 18 wells have obtained industrial oil and gas flows, of which 5 wells have obtained high-yield oil and gas flows.Driven by innovation, we have continuously researched the thin reservoir prediction technology of Daqingzi well, strengthened on-site trajectory control, and made commercial breakthroughs in the pilot test of three-dimensional well network production improvement test development, laying a solid foundation for shale oil to achieve production goals next year.

Highlight innovation and promote efficient construction and production.Guided by the goal of "dynamic efficiency reserves and construction efficiency output" and driven by efficiency creation, pilot tests for the evaluation and development of unused reserves have been increased to promote the efficient construction and production of long-term unused reserves.Set up major company-level projects, conduct detailed reservoir-forming research, and optimize the Daan-Haituozi, Moriqing and Yingtailong deep gas fields to carry out pilot development tests, and made important breakthroughs.

Control investment funds to realize benefit exploration.Focusing on strategic exploration areas, based on new zones, new strata, and new types, special risk exploration projects have been established to highlight zone research and target optimization. The main leaders personally supervise, and the two houses, the exploration division and the company review and check at the three levels to ensure the quality and efficiency of the target well position.Continue to strengthen investment control and take multiple measures to reduce costs at the same time: according to market-oriented quotas, carefully decompose and calculate the annual investment decomposition table, implement various projects and professional investments, and realize the “block-cutting” of investment in individual projects; implement the responsible entities for individual projects, track and evaluate the use of funds, adjust the whole process, and implement investment management and plans “both in place”.Actively promote the marketization of engineering and technical service prices, and through bidding and business negotiations, the prices of 43 single projects have been reduced.As of the end of October, drilling in the Songnan area had saved a total of more than 25 million yuan in funds, achieving the best investment and the best results.(Liu Xiaodi, Tang Mingshan)
