In Sichuan Basin and surrounding areas, the mud shale in Wufeng-Longmaxi Formation of Upper Ordovician to Lower Silurian is distributed in Leshan-Longnüsi and the Jialidong paleo-uplift area in the middle of Guizhou, and the thickens increasingly to the north, the south and the east. The fraction of organic carbon（TOC） of the shale is more than 1% in most areas of Sichuan Basin, belonging to sapropelicⅠkerogen, generally Ro〉2%.The black shale section consists of the sediments of transgression to maximum sea level, and the nowadays buried depth is relatively shallow. The buried depth in the south of Sichuan Basin is 1.5~3 km, that in west of Hubei and the east of Chongqing area is 1.5~3 km. The main target zone of the shale gas is the transitional zone from the east of Sichuan Basin to the west of Hubei and the east of Chongqing area. The buried depth of the shale in this zone is 2~3.5 km, and the front of the Daba mountain is the potential exploration advantageous area in future.
