全岩分析与干酪根分析的对比研究

全岩分析与干酪根分析是有机岩石学研究烃源岩的两种分析方法。笔者在简述这两种分析方法的基础上,系统对比了两者在油气评价中的应用。认为在显微组分特征、成因与分类,有机质丰度、类型与成熟度、烃类生成与运移特征等方面的研究中,全岩分析能提供更多的信息,且快速、经济、直观,较干酪根分析具有明显的优越性。目前虽还不能完全取代干酪根分析,但全岩分析必将发展成为今后有机岩石学研究的必需方法之一。

The Comparative Study between Whole Rock Analysis and Kerogen Analysis

Whole rock analysis and kerogen analysis are two analytical methods of studying hydrocarbon source rock in organic petrology. Basing on the brief introduction of the two methods, the authors systematicallly compare their applications in oil and gas assessment.We think that whole rock analysis provides more information than kerogen analysis in the study of the characteristics, origin and classification of macerals, the abundance, type,and maturity of organic matter, and the features of oil generation and migration. besides,whole rock analysis is faster, more economical and more perceivable than kerogen analysis, and so the former has obvious advantages. Though it has not completely replaced kerogen analysis so far, it is sure to be one of the methods necessary for the study of oarganic petrology in the future.
