KINETICS FEATURES OF GAS GENERATION IN HYDROCARBON SOURCE ROCKS AND ITS GEOCHEMICAL SIGNIFICANCES

Zhao Xigu Dang Changtao Liu Xiaoyan Lu Shuangfang (Daqing Petroleum Institute)  
Three samples-two source rocks(type I and II respectively)from song-liao basin and a brown coal(type III)from Hailar basin are heated in laboratory using a simulating experimental device made by ourselves as described in this paper. Based on the characteristics of gaseous products and kinetic principle of chemical reaction, kinetic models of gas generation in source rocks are established and the relevent kinetic parameters, i.e, order of reaction(n) apparent activation energy(E) and apparent frequency factor(A)are calculated. The kinetic parameters and the models are important for the study of evolutional mechanism of hydrocarbon in these source rocks and natural gas resource evolution.
