The correlation of these elements and lithology and given rock mineral contents can be used for distinct lithology and strata correlation as well as porosity and oil saturation corrections.

利用这些元素与地层岩性之间的相关关系以及提供的岩石矿物含量，可以确定不同的岩性、进行地层对比，修订地层的孔隙度、含油饱和度等参数。

On the basis of oil source correlation, the paper studied the organic microscopic component of the immature hydrocarbon source rock in santanghu basin.

本文在油源对比的基础上，对三塘湖盆地低熟源岩有机显微组分进行研究，认为盆地主力源岩芦草沟组主要生烃显微组份为腐泥无定型组。
