On October 18, Sino Petroleum and Chemical Corporation released a news report that Sino Petroleum Southwest Petroleum Bureau has made a major breakthrough in shale gas exploration in Sichuan Basin , and the geological resources are estimated to be implemented to reach 387.8 billion cubic meters.
Southwest Petroleum Bureau deployed Jinshi 103HF exploration well in Leshan City, Sichuan Province, and recently obtained a stable high-yield industrial gas flow, with a daily production of natural gas .2586 million cubic meters. Through multi-well drilling, it was confirmed that the resource volume of the production section of the Jinshi 103 well broke through to reach 387.8 billion cubic meters, and the resource volume of the entire shale section exceeded 1 trillion cubic meters. This is the first time that my country has made a major breakthrough in shale gas exploration in the Qingzhusi Formation formation of the Cambrian System.
Executive Director of Sinopec Southwest Petroleum Bureau Co., Ltd. Guo Tonglou:
The breakthrough of high-yield shale gas in Jinshi 103 well is of great significance. It will provide strong support for the in-depth promotion of the scale development of shale gas from the single layer system of the Longmaxi Formation to the new area, new layer system and new type fields, and help the construction of a national natural gas (shale gas) capacity base of 100 billion cubic meters in Sichuan and Chongqing.
Sichuan Basin mainly includes two main marine shale strata systems, Longmaxi Formation and Cambrian Qingzhusi Formation. Cambrian Qingzhusi Formation is the most promising marine shale gas exploration target in the future. This layer system has the characteristics of high-quality shale thin thickness, large longitudinal stress differences, and large difficulty in scale transformation. China Petroleum and Chemical Corporation Southwest Petroleum Bureau has innovatively adopted a new fracturing process and fracturing fluid system to achieve multi-stage fracturing transformation, laying the foundation for the high yield of Jinshi 103HF well.
Executive Director of Sinopec Southwest Petroleum Bureau Co., Ltd. Guo Tonglou:
Over the past decade, Sinopec Southwest Petroleum Bureau has vigorously increased its efforts in oil and gas exploration and development, built the world's first ultra-deep high-sulfur-containing biological reef gas field of more than 7,000 meters - Yuanba gas field , and discovered that my country's first deep shale gas field - Weirong shale gas field , etc., and produced a total of 52.95 billion cubic meters of natural gas.
