摘      要：Biogenic coalbed gas,how it is generated and the geochemical characteristics of the gas are gaining global *** ways coalbed gas is generated,the status of research on the generation mechanism and the methods of differentiating between biogenic gasses are *** generation of biogenic coalbed methane is consistent with anaerobic fermentation *** biogenic coalbed gas reservoirs are mainly generated by the process of CO2 *** substrates used by the microbes living in the coal include organic compounds,CO2,H2 and *** production ratio and quantity of biogenic coalbed methane depend on the exposed surface area,the solubility and permeability of the coal and the microbial concentration in the coal *** is generally believed that biogenic coalbed gas has a value for δ13C1*** H isotope ratio is controlled by both the environment and the generation mechanism:typically δD1-20%.Biogenic methane formed by CO2 reduction has more δD1 than that formed by acetate fermentation.
