This study reveal composition and the kinetic parameters of gaseous hydrocarbon by kinetic simulating experiment on secondary thermal cracking of the bitumen generated from marine carbonate rocks. The results can be used in nature extrapolation of laboratory kinetic data to very low, geological heating rates. The extrapolation indicates that methane generated under the secondary thermal stress 150℃O<1.9%). The heavy gaseous hydrocarbons (C2,C3,C 4-5) generated under 170℃O< 2.5%). The results can be used in quantitatively modeling the yield of gas generated from the oil that cracked from marine carbonate rocks and provides a new method for evaluating quantitatively the effective source rock.
