我国页岩气试产最高纪录刷新

Core Viewpoint - China Petroleum & Chemical Corporation (Sinopec) has made significant progress in the "Deep Earth Engineering: Sichuan-Chongqing Natural Gas Base," with two evaluation wells in the Sichuan Province's Ziyang shale gas field achieving production rates exceeding one million cubic meters, setting a new record for shale gas testing in China [1][3]. Group 1: Production Achievements - The two wells tested, Ziyang 2-501HF, achieved a daily gas production of 1.407 million cubic meters, marking the highest shale gas testing production record in China [1][3]. - Three wells have been put into production on the platform where the two evaluation wells are located, with each well maintaining a stable daily gas production of over 150,000 cubic meters, indicating a promising outlook for the development of ultra-deep shale gas in the Sichuan Basin [3]. Group 2: Geological and Technical Innovations - The wells are targeting the Cambrian system, which is 540 million years old, representing a new type of shale gas and the oldest shale system to achieve large-scale exploration globally [3]. - Sinopec has implemented a pioneering ultra-deep shale gas development test well group at the Ziyang 2 well site, utilizing a combination of natural and artificial fractures to unlock nearly 5,000 meters of ultra-deep shale gas reservoirs, leading to high-yield gas flows [3][4]. Group 3: Strategic Importance and Historical Context - The successful exploration and development of Cambrian shale gas represent a strategic breakthrough in both the breadth and depth of shale gas exploration in China, confirming the potential for large-scale resource increase and production [4][6]. - Sinopec has played a crucial role in the commercialization of shale gas in China, having discovered the Fuling shale gas field in 2012, which marked the beginning of shale gas commercialization in the country, making China the third nation after the U.S. and Canada to achieve this [6].
