摘　　要：采用低温催化法研究未熟烃源岩催化脂肪酸酯生烃的动力学具有地质学上的实际意义。在模拟未熟油生成的地质条件下,选择十八烷酸甲酯作为模型化合物,以6种抽提有机质的未熟烃源岩作为载体,通过动力学的方法考察了未熟烃源岩矿物对脂肪酸酯生烃反应的催化作用。实验结果表明,在地质温度小于200℃的条件下,未熟烃源岩矿物催化脂肪酸酯生烃反应的活化能与碳酸盐含量、粘土总含量有一定的相关性。Taking catalyzing method at low temperature, kinetics study on hydrocarbon generation of fatty add ester catalyzed by immature oil source rocks has practice meaning in the geology. Methyl stearate is chosen as the rind compound absorbed by means of six different kinds of immature oil source rock. The catalytic effect of minerals on the hydrocarbon generation by kinetics method was investigated. The results show that active energy of hydrocarbon generation reaction frown methyl stcarate catalyzed by immature oil source rocks minerals is certain correlativity to contents of carbonate and day when geology temperature is less 200℃.
