烃源岩中有机质测定及分布规律研究

烃源岩是一种富含有机质和各种无机矿物的集合体,而有机质是未熟-低熟原油和烃源岩抽提物的常见组分。采用不同方法对烃源岩进行有机质抽提并进行了四组分分析,考察了不同层位和深度有机质总抽提率和四组分的分布规律。结果表明,三元溶剂的抽提率相对较高,并且总体含量上在Es3有机质的含量较高,颜色深的页岩含有机质的量较高。

Determination and Distribution Law Study on Organic Matters in Oil Source Rocks

The oil source rock is a aggregation of rich organic matters and many kinds of inorganic mineral. But organic matters are ordinary components in the immature oil and the oil source rock. In this paper, organic matters in oil source rock are removed by different methods, and carry through our components analysis. Assemble removal ratio of organic matter and distribution law of four components are researched in different stratum and depth. The results show that removal ratio of tri- components solvent is comparatively higher, Es3 organic matter content is higher in total content, deep color shale organic matter content is higher.
