作者通过热模拟试验及各种分析实验,对干酪根的结构进行了研究。研究结果表明,(1)富氧类型的干酪根具有内催化作用,这种内催化作用超过了粘土矿物的催化作用;(2)干酪根的原生结构在时间-空间地质历史过程中,发生了老化和变蚀,使干酪根脱去大量的杂原子桥链,热降解反应速度也随之减低。这就为干酪根热降解机理的研究提供了理论依据。

Based on thermal simulation and various analytical experiments, the authors have made a deep research on the structure of kerogen, which shows. 1. the oxygen-enriched type of kerogen possesses inner catalytical effect which exceeds that of clay minerals. 2. aging and alteration of the primary structure of kerogen took place during geological history, many heteroatomic chains of kerogen broke down, and the rate of thermal degradation was reduced. This study provides theoretical evidence for studying mechanism of thermal degradation of Kerogen.
