Investigation on Secondary Generation of Hydrocarbons by Thermal Modelling of Kerogen

Abstract: Based on results from thermal modelling experiments of kerogens,this paper presents a brief discussion on secondary generation of hydrocarbons. Geological effects, such as structural movement, etc.,may result in liftion or denudation of source rocks which do not enter highly-and post-mature phases, which causes the decrease of geotemperature of the source rocks and the cease of hydrocarbon generation. While the source rocks subside .again, the geotemperature increases, and when it reachs a certain point, the unexhaused kerogens may generate hydrocarbons again.The generated oil-gas amount with the continuous process of hydrocarbon generation is close to the total amounts of twice generations, indicating that hydrocarbon-generating amount is not affected by the secondary hydrocarbon generation that only defer generating oil and gas.
