| 摘 要： | 运用地球化学研究手段,对东濮凹陷文留地区原油、油砂和泥岩进行了族组分、碳同位素和饱和烃色谱-质谱分析,文留地区沙三段原油族组分含量表现为高饱和烃、芳烃与低非烃和沥青质;原油族组分碳同位素具有海相有机质的碳同位素组成特征,反映有机质生物源主要来自盐湖相的水生生物和细菌;植烷优势明显,甾烷参数C29αα 20S/(20S+20R)为0.37～0.57,C29ββ/(ββ+αα)为0.41～0.65,重排甾烷和γ蜡烷含量相对较高,γ蜡烷指数达到0.55～0.84,表现为典型的盐湖相还原环境下形成的原油;油源对比分析认为文留地区沙三段原油与沙三段烃源岩关系密切,具有较好的亲缘关系. |

| Abstract: | Group composition and carbon isotope of oil,chromatogram and mass spectrum of aliphatic are analyzed from samples source rock,crude oil and oil sand in Wenliu area Dongpu depression.The group composition of crude oil shows high contents of saturated hydrocarbons,aromatics and low non-hydrocarbon and asphaltene.The characteristics of carbon isotope similar to that of marine organic matter,indicate that organic matter mainly originated from the Salt Lake farcies aquatic organisms and bacteria.There is predomi... |
