On September 17, reporters learned from the Sinopec News Office that significant progress has been made in Sinopec’s “Deep Earth Project · Sichuan-Chongqing Natural Gas Base.” The production levels measured in the two evaluation wells located in the Ziyang shale gas field in Sichuan Province exceeded one million cubic meters each. In particular, Well Ziyue 2-501HF achieved a daily gas production of 1.407 million cubic meters, setting a new record for the highest shale gas production ever recorded in China. At present, 3 wells have been put into operation on the Ziyang Well 2 platform, with each well producing over 150,000 cubic meters of gas per day on a stable basis. This demonstrates the good prospects for the efficient development of ultra-deep shale gas in the Sichuan Basin, and it holds great significance for advancing shale gas development in China. In 2024, the Southwest Oil and Gas Branch deployed the first ultra-deep shale gas development test well cluster at the Ziyang Well Platform, utilizing a combination of natural fractures and artificially created fractures to access shale gas reservoirs at depths of nearly 5,000 meters; this approach confirmed that Cambrian shale gas holds potential for increased reserves and production on a large scale. In response to the complex geological engineering conditions in the Ziyang area, characterized by thick hard-to-drill formations, deep burial depths, high pressures, and high temperatures, the research team achieved safe, efficient, and rapid well completion by strengthening the integration of geological engineering practices and applying technologies such as heat resistance, precise pressure control, and effective sealing ； For the first time, the largest domestic integrated sand-carrying fracturing device was used, enabling the development of a super-deep shale gas fracturing technology. This technology is complemented by a ultra-high-pressure completion system and key processes, all of which contribute effectively to the creation of high-yield wells. Sinopec continues to promote the high-quality development of China’s shale gas industry. The Fuling shale gas field was discovered at the end of 2012, marking the beginning of the commercial development of shale gas in China. In 2018, China’s first deep shale gas field with reserves exceeding 100 billion cubic meters was discovered—the Weirong Shale Gas Field—and large-scale development of it was carried out. In August 2024, two shale gas fields in Yongchuan and Hongxing with reserves of 100 billion cubic meters each were discovered, making a positive contribution to the development of natural gas production bases in Sichuan and Chongqing with capacities of 100 billion cubic meters each, as well as to ensuring **energy security.
