摘要：

有机地球化学的基本原理及研究方法是认识和划分含油气系统的基础,烃源岩是4 个成藏要素之最。盆地中有几套不同的烃源岩就有几个不同的含油气系统;在同一盆地中,若有两个或更多的烃源岩彼此重叠,则形成复式含油气系统,我国东部第三纪断陷盆地及西部多旋回构造盆地常发育此类系统。含油气系统中的生烃时间、排烃时间及聚集时间由生物标志化合物的分析与对比确定。多期生油表明含油气系统经历了多期改造。

关键词: 含油气系统, 有机地球化学, 烃源岩, 生物标志物

Abstract:

The basic principles of organic geochemistry and research methods are the foundations for recognizing and classifying petroleum system,and source rock is the most important factor among all the four factors of pool forming.The number of different sets of source rocks in a basin is the number of petroleum systems of it.If a basin contains two or more sets of superimposed source rocks,there would form multiple petroleum system.Such kind of petroleum system usually developed in the Eogene fault depressed basins in East China and multicycle basins in West China.The time of hydrocarbon generation,expulsion and accumulation could be determined through the analysis and correlation of biomarkers of the system.Multiphase of oil generation indicates that the system underwent multiphase of reformation.

Key words: petroleum system, organic geochemistry, source rock, biomarker
