摘要： 通过对溱潼凹陷低熟油中不同类型饱和烃生源标志物的分析认为,其生源构成具有多源复合型特征,高等植物和菌藻类微生物是该凹陷低熟油最重要的成烃母质,分别占生源构成的40%～70%和12%～40%.另外根据不同层位生油岩与低熟原油生物标志物地球化学特征,分析了研究区低熟油的主要油源。

Abstract: The biomarker assemblage of immature crude oil from Qintong sag shows its multi-source complex characteristics. Higher plant and thallogen microbes are the most important hydrocarbon-generating kerogen of the oil, accounting for 40%~70% and 12%~40% of the total amount of hydrocarbon generation, respectively. Meanwhile, according to the source rocks in different horizons and the biomarker geochemistry, the main oil source of immature crude oil in this area is analyzed.

Key words: Qintong sag, immature oil, biomarker, oil-source correlation
