China News Service, Chengdu, January 2 (Du Cheng, Pang Shuai, He Bing) PetroChina Southwest Oil and Gas Field Company ("Southwest Oil and Gas Field") revealed on the 2nd that it will produce 35.41 billion cubic meters of natural gas in 2021, a year-on-year increase of 3.6 billion cubic meters from 2020. An increase of 11.3%, the annual increase accounted for more than half of PetroChina, achieving a high-quality start to the "14th Five-Year Plan" and helping China's "Qing Daqing" construction.

　　In 2021, the Southwest Oil and Gas Field aims to "create a new era of party building work and the entire natural gas industry chain innovation and efficiency double benchmark enterprise, striving to win a total victory in the new battle of 50 billion production capacity", and become the main force in the production of natural gas and the vanguard of shale gas development. , The conventional gas, shale gas, and tight gas "troika" have made concerted efforts. The annual gas production has maintained double-digit growth for three consecutive years, and the oil and gas equivalent has exceeded 28 million tons.

　　According to reports, the conventional gas of the Southwest Oil and Gas Field will account for 64% of the total production in 2021, reaching 22.91 billion cubic meters, becoming the “ballast rock” of the highest production.

In the new area, the Southwest Oil and Gas Field has fully completed the Anyue Gas Field's 15 billion cubic meters of super large gas field; in the old area, a new pattern of "stabilized production + increased production" 10 billion cubic meters has been formed, and the annual output of the old gas fields has maintained more than 4 billion cubic meters. 1.5 billion cubic meters to accelerate the completion of preparations for the development of high sulfur content in northeastern Sichuan.

　　After the production of shale gas in 2020 broke 10 billion for the first time, it will increase by 1.05 billion cubic meters year-on-year to 11.17 billion cubic meters in 2021, becoming the “growth pole” of Southwest oil and gas fields.

The Southwest Oil and Gas Field did a good job in the production of new shale gas wells, the maintenance of old wells, and the construction of key surface projects. 207 new wells were put into production and 339 wells were drilled.

The mid-deep shale gas in southern Sichuan maintained a stable production of 10 billion cubic meters, focused evaluation of the deep shale gas in the Luzhou block, locked the first trillion cubic meters of deep shale gas reserves, and promoted a new round of production preparations.

　　It is reported that the Southwest Oil and Gas Field will produce 1.32 billion cubic meters of tight gas annually in 2021, a year-on-year increase of 31%, becoming a "new position" for higher production.

The company’s precise block geology and seismic research, innovatively formed multi-stage overlapping narrow channel reservoir comprehensive evaluation and development optimization technology, established a geological engineering integration high-yield well deployment model, and realized the success rate of exploratory wells and the efficiency of development wells "100%". A batch of high-yield wells was drilled, setting a new high in tight gas test production in the Shaximiao Formation of the basin.

　　In addition, oil and gas exploration in the Southwest Oil and Gas Field has also opened up new prospects. Major new achievements have been made in the four major fields of the Penglai gas zone in the central Sichuan paleo-uplift, deep shale gas in southern Sichuan, tight continental gas, and deep marine facies in western Sichuan. Geological reserves hit a record high, formed two trillion gas regions, and achieved a hundred billion-level increase in reserves in the two major areas.

Natural gas sales in Sichuan and Chongqing hit a record high, and a number of key projects including the Weiyuan-Leshan pipeline were completed and put into operation.

　　It is worth mentioning that the quality and efficiency of the Southwest Oil and Gas Field has been improved simultaneously with the output.

The success rate of exploratory wells was 70%, and the platform margin zone of the Deng 4 gas reservoir used 3.6 billion development workload to build 6 billion cubic meters of annual production...A series of data showed that the Southwest Oil and Gas Field has entered a new stage of high-quality development during the "14th Five-Year Plan" period.
