摘　　要：基于水松加水热模拟实验,对正构烷烃、类异戊二烯和甾烷类化合物等水松热解主要产物进行了研究。实验结果表明,随模拟实验温度升高,热解产物中,正构烷烃含量逐渐增加,主峰碳也由最初的n-C27逐步前移,Pr/n-C17和Ph/n-C18比值增大,规则甾烷分布由“V”形转变为反“L”形,达到340℃后各类化合物不稳定发生热裂解,多种参数发生改变。通过探讨生物标志化合物在有机质熟化过程中的演化规律,为陆相有机质生烃机理的研究提供基础认识。Based on the hydrothermal simulation experiments of water pine addition,the main products of water pine pyrolysis,such as n-alkanes,isoprenoids and steroidal alkanes,were investigated.The experimental results show that with the increase of simulation temperature,the content of n-alkanes in the pyrolysis products gradually increases,the main peak carbon gradually moves forward from the initial n-C 27,the ratio of Pr/n-C 17 and Ph/n-C 18 increased,and the distribution form of regular steroidal alkanes is transformed from the“V”type to the anti-“L”type.After reaching 340℃all kinds of compounds are unstable and thermally cleaved,and a variety of parameters are changed.By exploring the evolution law of biomarker compounds in the process of organic matter maturation,a basic understanding for the study of hydrocarbon generation mechanism in terrestrial organic matter is provided.
