College of Science, China University of Petroleum, Beijing 102249, China

摘要

摘要: 针对川东北地区过成熟干酪根样品,采用固定床反应器进行催化加氢热解,利用GC-MS技术对产物进行检测并与源岩抽提产物进行对比,考察了饱和烃中甾烷、萜烷,芳烃中硫芴类和三芴类生物标志物的分布特征及地球化学信息,根据藿烷指数、姥鲛烷/植烷之比、伽马蜡烷指数、规则甾烷/17α(H)-藿烷、C₂₇-C₂₈-C₂₉甾烷、重排甾烷/规则甾烷、硫芴系列化合物、三芴化合物等参数的结果,研究表明川东北烃源岩沉积的环境为缺氧的亚氧化、非超盐度、贫粘土的海相碳酸盐岩,沉积有机质来源于浮游生物。

Abstract: The over-mature kerogen samples from the northeast Sichuan Basin were studied by catalytic hydropyrolysis in a fixed-bed reactor.The products were analyzed with GC-MS and were compared with source rock extracts.The distribution features and geochemical information of sterane,terpane in saturate hydrocarbon and dibenzothiophene and fluorene in aromatic hydrocarbon were studied.According to parameters such as hopane index,Pr/Ph,gammacerane index,regular sterane/17α(H)-hopane,C₂₇-C₂₈-C₂₉ regular sterane,rearranged sterane/regular sterane,dibenzothiophene and fluorene,the source rocks in the northeast Sichuan Basin were marine carbonate ones with little clay deposited in anoxygenous and unhypersaline environment.The biogenic sources were plankton.
