Zhong Guo Xin Wen Wang·2025-09-17 10:52Group 1 - The core point of the news is that China's largest shale gas production base, the Sichuan Southern Shale Gas Field, has achieved a cumulative gas production of 100 billion cubic meters, making it the first shale gas field in China to exceed this milestone [1][2] - The 100 billion cubic meters of shale gas can meet the annual gas consumption of approximately 260 million households (about 810 million people) at an average daily usage of 1 cubic meter per household, significantly contributing to regional GDP growth of 861 billion RMB and creating around 4.5 million jobs, with a contribution rate of about 7.5% to regional employment [1] - China National Petroleum Corporation (CNPC) has been a pioneer in shale gas exploration and development since 2006, achieving several breakthroughs, including drilling the first shale gas well in China and establishing the Changning-Weiyuan National Shale Gas Industry Demonstration Zone [1] Group 2 - Technically, CNPC has improved the deep well completion cycle to less than 85 days through techniques such as "wellbore slimming" and "one-trip drilling," and has enhanced the estimated ultimate recovery (EUR) of deep shale gas by over 10% through innovative "layered W-type well arrangement" models [2] - By the end of 2025, the annual production of the Sichuan Southern Shale Gas Field is expected to exceed 16 billion cubic meters, accounting for about 60% of China's annual shale gas production, providing solid energy support for initiatives like the Belt and Road, the Yangtze River Economic Belt, and the Chengdu-Chongqing Economic Circle [2]
