The potential of shale gas of Sichuan basin is enormous. In the Sizhufu syncline in this area, the Jx well has a successful unconventional industrial airstream in the shale of Zhenzhuchong section of Zhiliujing group. In other 2 wells in Dongyuemiao section of zhiliujing group, the industrial value also appears. Research indicates that in the western Hubei province and eastern Chongqing province, there are two different kinds of shale in Zhiliujing group. One is “shale with sandstone”which means layers of sandstone exist in layers of shale. Another is “share with limestone” which means layers of shale are sedimented with thin layers of limestone. The shale gas in both kinds of shale is active and has a large potential when the shale are mined.
