Wumaying buried hill is a deeply buried one situated in south of Huanghua depression. Commercial gas reservoir originated and stored in Paleozoic was found at the weathering crust on the top of Ordovician when drilling Wushen-1 well. It’s natural gas mainly originated from coal-bearing formation of C-P; Carbon isotope analysis, gas drying coefficient and naphthene index show that there is diversity in maturity of different component of the gas and the reverse carbon isotope series of gas.
Key words: Wumaying; Huanghua depression; Deeply buried hill; Coal-derived gas.
