Shale gas is a new replaceable unconventional energy source, which is different from conventional gas reservoir in its recognition and evaluation. The study of shale thickness, depth, mineral composition and characteristics of organic geochemistry shows that the shale indicates great thickness, deep burial, high eoment of fragile mineral, high organic carbon content in Lower Cambrian, and moderate thermal maturity in pariial areas. Shale is of small thickness, deep burial, high content of clay mineral and low content of organic carbon, and high thermal maturity in partial area in Upper Ordovician and Lower Sih, rian. Permian shale is thick, which is buried relatively shallow. Its composition of fragile mineral and organic carbon are high, meanwhile, its thermal maturity is proper. So exploration potential of Permian shale is the greatest in Anhui, and Lower Cambrian takes second place.
