摘要
烃源岩是含油气系统和油气成藏的基础,国内外油气地质学家对其进行了多方面的研究。目前烃源岩排烃研究已取得了很大进展,但也存在着较多的问题。排烃门限理论能够很好地解决烃源岩的排烃问题,根据此理论可以定量计算排烃量,并对其排烃模型进行了修正。排烃门限理论目前已被用来判别油气源岩、综合定量评价源岩、研究油气运聚机理与成藏模式。
Hydrocarbon source rock is the foundation of petroleum system and hydrocarbon accumulation,and the domestic and international oil geologists have carried on a various research.The studies of hydrocarbon expulsion of source rock have made a great progress,but some problems still exist currently.This thesis elaborates problems mentioned in former theories.It has been proved that the hydrocarbon expulsion threshold theory can well resolve hydrocarbon expulsion problems of source rock,and we can calculate quantificationally the hydrocarbon expulsion quantity.Furthermore,the hydrocarbon expulsion model is modified.So far the hydrocarbon expulsion threshold theory have already been used to distinguish the source rock,evaluate quantitatively source rock,and study petroleum migration mechanism and reservoir forming model.
