Abstract: Starting with the six aspects such as formation temperature, formation water salinity, depositional rate, organic matter abundance and type, microbial population and shallow inhibition effect, this paper analyzes in detail each factor influencing the microbial activity, the growth and reproduction of methane bacteria and the generation of biogas of the Neogene-Quaternary in Hetao basin. It is revealed that the favorable layer of biogas source rock development lies to the upper and middle sections of the Pleistocene in Hetao basin.

Key words: Hetao basin, biogas, geochemistry, methane bacteria, genesis, origin
