摘要
本文主要以陆相断陷盆地为例,综合利用地质、测井和有机地球化学分析的方法,探讨油气初次运移的深度、主要运移期和相态。表明,欠压实生油岩压实历史的研究、正常生油岩残余烃含量或含油饱和度的研究是确定其初次运移期的关键。
By means of methods of geology, log and geochemical analysis for terrestrial fault basins, the depth, the period of main migration and the phase of primary migration of hydrocarbons are discussed in this paper. It is indicated that the key to the study of the main period of primary migration is historical analysis of undercompacted oil source rocks and calculation of residual hydrocarbon and oil saturation of normal compacted oil source rocks.
