| 摘 要： | 本文采用自制的实验装置,以褐煤和大庆泥岩为样品进行了热压模拟实验,根据模拟实验的气态产物特征和化学反应动力学原理,建立了烃源岩成气反应的动力学模型,计算出烃源岩成气反应的动力学参数,如反应级数(n)、反应速率常数(K)、表观活化能(E)和表观频率因子(A)等.所得动力学参数和动力学模型对于揭示烃源岩演化机理及进行天然气资源评价具有一定的实用价值.

| Abstract: | 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. |
