摘要
According to the ideas of exploration and the reservoir accumulation characteristics of shale gas, the authors collected shale gas data in Ziliujing Formation from a batch of exploratory wells in Yuanba area of Sichuan Basin. And industrial gas flow has been discovered in three wells of the exploratory wells. Research shows that Ziliujing Formation in Yuanba area is formed in shallow lake-semi-deep lake environment. Thick dark shale, high content of organic carbon and moderate thermal maturity of organic matter which is at the peak of gas production are developed in Ziliujing Formation.
