| 摘 要： | 采用热解方法对地质体中沉积有机质——源岩干酪根和固体沥青进行了生烃动力学研究，建立了平行一级反应动力学模型，求取了动力学参数活化能E和指数前因子A，主要反应的活化能集中在170—210kJ／mol的范围内。反映了干酪根和沥青是一个大分子网络体系，其热解过程涉及不同能级化学键的断裂。实验所得到的沉积有机质热解动力学参数，可用于样品母质类型判别和成熟度确定。

| Abstract: | Pyrolysis method is used to investigate the hydrocarbon generating kinetics of sedimentary organic matter,source rock kerogen and solid bitumen.The parallel first order reaction model is developed.The activation energy E and exponential front gene A of kinetic parameters for hydrocarbon formation are determined by using the developed model.The distribution of the apparent activation energy ranges from 125 kJ/mol to 250 kJ/mol,and the main reactions have the activation energy of 170~210 kJ/mol,indicating the... |
