Tuha basin is very rich in natural gas resource. This paper presents the classification of the gas resources in terms of gas origin, distribution and accumulation pattern into three types： Type-Ⅰ gas is mainly distributed in the Sanjianfang formation and Triassic strata; Type-Ⅱ is in the Middle Jurassic; Type-III is widespread except for the Triassic, in which tight sandstone gas reservoir origin type belongs to the Type-Ⅲ. The natural gas accumulation can be divided into four models, such as lateral differentiation, vertical differentiation, near-source differentiation and hybrid accumulation ones, among which near-source differentiation is the main gas accumulation model and pos-sesses greater exploration potential in adjacent sags of the eastern Tuha basin.
