摘要： 根据烃源岩有机质丰度并结台地质分析方法,提出了油源丰度指数的概念并以此对塔里木盆地西南坳陷的烃源岩进行了评价。认为中新统、上白垩统—下第三系为较差—非烃源岩,中、下侏罗统暗色泥岩、石炭系—下二叠统和寒武—奥陶系暗色碳酸盐岩为较好—好的烃源岩,古生界的泥质岩基本为非烃源岩。

Abstract: The concept of oil source abundance index is presented by combining organic abundance of source rock with geological analysis, and applied in Southwest depression of Tarim basin. It is suggested that Miocene and Upper Cretaceous-Paleogene can generate few or no hydrocarbons dark mudstone in Mid - Lower Jurassic, and dark carbonate rock in Carboniferous - Lower Permian and Cambrian-Ordovician have relatively higher hydrocarbon generating potential, and argillaceous rock of Palaeozoic can generate no hydrocarbon.

Key words: Tarim basin, Southwest depression, Source rock evaluation, Organic matter abundance
