Through studying the organic matter abundance and types of gas source rocks, reservoirs, covers, source-reservoir-cap assemblage, migration, trap factors and so on, the main conclusions obtained are as follows. The source rocks with high content of organic carbon in the Baoshan Basin are favorable to biogeneic gas production. The total pore structure is not so good, more of the geological conditions are high porosity and low permeability, some are high porosity and middle permeability. The cover is mainly physical properties and hydrocarbon concentration composite confined reservoir. The source-reservoir-cap assemblage is mainly a self-generation and self-accumulation. The traps are mainly structural-stratigraphic combination traps. Therefore, based on the study, the paper proposes the accumulation model of biogenic gas.
