Exploration degree of Tarim Basin, however, is not high, so effective source rock distribution cannot be precisely defined only by geochemical index of the well sites.

而塔里木盆地勘探程度不高，仅凭井点的地化指标，是不能准确圈定有效烃源岩分布的。

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.

根据烃源岩有机质丰度并结合地质分析方法，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。

Gaseous hydrocarbon generation of gas source rock is a key index in evaluating gas source rock. It is also an important parameter of basin resource assessment.

气源岩的气态烃产率是评价气源岩生气潜力的重要指标，也是盆地资源评价中的重要参数。
