| Abstract: | A new kinetic model of hydrocarbon generation and its simplified coal-generated gas model in a half open system is established, in which coal or kerogen is degrated into gas and oil, then the un-expelled oil in source rock is cracked into gas as the maturation increases, and gas and oil are expelled simultaneously during the formation of hydrocarbon. The model can be used to the numerical simulation of gas and oil generation in any type of basins by selection proper model and parameters according to given kinetic parameters. |
