Abstract: The pyrolysis simulation of the asphaltenes in marine crude oil in Tarim Basin was carried out in an anhydrous closed system under a constant pressure of 50 MPa. The gasgeneration mechanism of asphaltene in marine crude oil was discussed on the basis of the yields and carbon isotopic composition of gaseous hydrocarbons and the yields of pyrobitumen. Kinetic parameters of gaseous hydrocarbons generation generated from asphaltene was obtained by kinetic calculation and extrapolated to geological conditions. Gaseous hydrocarbon begin to generate from asphaltene around Easy%Ro 0.8, and the conversion rate of gaseous hydrocarbon reach to 1 at Easy%Ro 2.65. The main gasgeneration period of asphaltene pyrolysis range from Easy%Ro 0.9 (conversion rate 0.1) to Easy% Ro 2.3 (conversion rate 0.9). The application result can provide a theoretical basis for identification and assessment of oil cracking gas and exploration decision of marine carbonate area in China. 
