摘要
选择十六烷酸甲酯和十八烷酸甲酯组成的混合酯为模型反应物,采用不同的方法对未熟烃源岩进行有机质抽提,以连串反应的动力学模型考察抽提前后未熟烃源岩低温催化混合酯水解率及生烃率的变化,分析有机质组分对催化反应的影响.结果表明:相比于抽提有机质后的未熟烃源岩,含有有机质的未熟烃源岩低温催化混合酯的水解率和生烃率更高.
The ester mixed by methyl hexadecanoate and methyl stearate is as model reactant,and organic matters are extracted from immature hydrocarbon source rocks using different methods.The change of the hydrolysis rate and hydrocarbon generation rate of the mixed ester catalyzed by the immature hydrocarbon source rocks before and after extracting organic maters at low temperature is examined with the kinetic model of consecutive catalytic reaction,and the effect of the organic matters on the catalytic reaction is analyzed.The results show that,compared with the immature hydrocarbon source rocks after extracting organic matters,the hydrolysis and hydrocarbon generation rates of the mixed ester catalyzed by the hydrocarbon source rocks before extracting organic matters are higher.
