Continuous innovation in oil and gas exploration technology has made shale gas an important area for increasing oil and gas production in China.

On the 13th, it was learned from China Petrochemical Corporation that a shale gas exploration well located in the Sichuan Basin has a vertical depth exceeding 5300 meters, breaking the record for the deepest shale gas well in China, providing valuable experience for deep shale gas exploration in the country. China has the characteristic of being "rich in coal, poor in oil, and lacking in gas" and is a large importer of oil and gas. In recent years, with continuous innovation in key technologies for oil and gas exploration and development, shale gas is becoming a replacement field for oil and gas exploration and sustainable increase in reserves and production in China.
