    Abstract
  • Generation of hydrocarbon from kerogen is one of important genetic types of abnormal pressure in source rock.Because the pressurizing caused by generation was taking place during the period of genera ting and expulsion,it is difficult to recover or calculate it directly.Usually it can be measured by numerical modeling.The mathematical model of pressurizing was built according to the physico chemical mechanism of generation.It shows that the more the generated hydrocarbon,and the more compact the source rock,the larger the intensity of pressurizing.The pressurizing caused by gas generation is stronger than that caused by oil generation.The pressurizing caused by generation can be modeled,and also the expulsion through microfracture caused by the pressurizing can be recovered by using this mathematical model.Numerical modeling on pressurizing caused by generation has been effectivelg applied in several typical petroleum basins in China.
