16日从中国石油获悉，我国最大的煤岩气田——中国石油大吉气田年产能突破40亿立方米，产量占全国煤岩气总产量的四分之三以上，成为我国天然气产量增长的重要接替资源。

On the 16th, China National Petroleum Corporation announced that the largest coalbed methane field in China - the Dagiji Gas Field of China National Petroleum Corporation - has achieved an annual production capacity of over 4 billion cubic meters. Its output accounts for more than three quarters of the total coalbed methane production in the country, making it an important replacement resource for the growth of China's natural gas production.

　　煤岩气是一种吸附或者游离在地下深层煤层中的非常规天然气资源，通常埋藏深度超过1500米，勘探开发前景广阔。

Coalbed methane is a type of unconventional natural gas resource that is adsorbed or free within the deep coal seams underground. It is usually buried at a depth of over 1500 meters and has broad prospects for exploration and development.

中国石油煤岩气重点实验室的研究成果显示，我国煤岩气地质资源量可达50万亿立方米，其中鄂尔多斯盆地资源量超25万亿立方米。国家首个煤岩气示范区项目——大吉气田位于鄂尔多斯盆地东缘山西省西南部。

The research results of the Key Laboratory of Coal and Rock Gas of China Petroleum show that the geological resources of coal and rock gas in China can reach 50 trillion cubic meters, among which the resources in the Ordos Basin exceed 25 trillion cubic meters. The country's first coal and rock gas demonstration project - Da Ji Gas Field is located at the eastern edge of the Ordos Basin in the southwestern part of Shanxi Province.

今年以来，中石油煤层气公司新钻井16口，新建产能2.5亿立方米，推动该气田日产气量突破1100万立方米，同比增长32%。

Since the beginning of this year, the Coalbed Methane Company of China National Petroleum Corporation has drilled 16 new wells and increased production capacity by 250 million cubic meters. This has led to the daily gas output of this gas field exceeding 11 million cubic meters, an increase of 32% compared to the previous year.

　　与常规天然气相比，煤岩气埋藏深、地质条件复杂，开采技术门槛高。中石油煤层气公司持续深化煤岩气勘探开发理论创新，构建形成煤岩气富集理论体系，精准揭示深部煤岩层段气体“吸附—游离”双相赋存规律。

Compared with conventional natural gas, coalbed methane is buried deeper and has complex geological conditions, with high technical requirements for extraction. The China National Petroleum Corporation's Coalbed Gas Company has continuously deepened theoretical innovation in coalbed gas exploration and development, and has established a theoretical system for coalbed gas enrichment, accurately revealing the dual-phase (adsorption and free) gas occurrence pattern in deep coalbed layers.

坚持以技术创新为引擎，全力推动煤岩气开发提速增效，成功研发一批关键核心技术，有力支撑煤岩气规模效益开发。

Focusing on technological innovation as the driving force, we have made every effort to accelerate and enhance the development of coal and shale gas, successfully developing a number of key core technologies, which have effectively supported the large-scale and efficient development of coal and shale gas.

2019年，首口煤岩气井大吉3-7井获得工业气流。

In 2019, the first coal seam gas well, Da Ji 3-7 well, achieved industrial gas flow.

2021年12月，吉深6-7井日产超过10万立方米，成为我国首口煤岩气高效开发的“突破井”。

In December 2021, the Ji Shen 6-7 well produced over 100,000 cubic meters of gas per day, becoming the first "breakthrough well" in the efficient development of coal and rock gas in China.

2023年到2025年，大吉气田仅用3年时间，实现了煤岩气产量的阶梯式高速增长，持续领跑我国煤岩气产业发展。目前，大吉气田二期产能建设项目正在扎实推进，项目建成后将新增年产15亿立方米的产能规模。

From 2023 to 2025, the Dagji Gas Field achieved a stepwise and rapid growth in coal and shale gas production within just three years, consistently leading the development of China's coal and shale gas industry. Currently, the second-phase capacity expansion project of the Dagji Gas Field is being actively implemented, and upon completion, it will increase the annual production capacity to 1.5 billion cubic meters.
