| 摘 要： | 根据大量的烃源岩地球化学数据,分析了北塘凹陷古近系烃源岩的地球化学特征,从有机碳含量(TOC)、氯仿沥青"A"、总烃含量、S1+S2、有机质类型和成熟度(R0)等方面对古近系烃源岩进行了系统分析,结果表明北塘凹陷东三段、沙一段和沙三段是本区的烃源岩层段,其中沙三段烃源岩生烃指标最好,是本区的主力烃源岩层段.烃源岩的模拟...

| Abstract: | Based on large quantity of organic geochemistry data,the geochemistry characteristics are systematically analyzed on organic carbonate content(TOC),chloroform bitumen A,overall hydrocarbon content,S1+S2,organic matter types and maturity(Ro%) and so on.It shows that the Dong 3 Member,Sha 1 Member and Sha 3 Member are the main oil source beds of Beitang sag,especially,Sha 3 Member is the best in source rock quality.The model results indicate that(1) The depth of oil generative threshold is about 2 390 m,and t... |
