According to the characteristics of deep basin gas pools in the North America and Welson's theories about the lithogenesis of the hydrocarbon bearing and water-bearing strata, this article presents that deep basin gas pools form when a relative dry zone is created between the water saturation zone and gas water transitional zone after lithogenesis of the reservoirs evolves into a certain phrase. On the basis of well hole and seismic data, combined with the physical properties of the Pingshi sandstone in Anpeng Zhaowa Region, this article analyses formation conditions and characteristics of the deep-basin oil-gas pools, and points out that the nonmarine deep\|depression region in the lake basin also boasts positive geologic background for deep-basin gas pools.
Key words: Biyang Sag; High maturation period; Deep; basin oil-gas pool.
