含油气盆地输导体系研究进展

Study on Passage System of Petroliferous Basins

输导体系是油气运移的通道,对油气成藏具有控制作用。本文在对前人文献调研的基础上,梳理了输导体系的概念和分类,将输导体系分为砂岩输导体、断裂输导体和不整合输导体。总结了砂岩、断裂和不整合输导体的研究思路和存在问题,指出输导体系研究要从动态角度出发,以油气运移成藏时期的输导性能研究为主,结合对输导体进行静态精细刻画,指出油气运移的优势方向。

The passage system is the way of hydrocarbon migration,which has a obvious controlling effect on hydrocarbon accumulation.This paper analyzes the concept and classification of the passage system based on the previous studies,as a result,the passage system was divided into sandstone,fault and unconformity.The research methods and existing problems of sandstone,fault and unconformity are summarized.It’s pointed out that the study of passage system should be based on the dynamic point of view and focused on the passage capacity during the period of hydrocarbon migration and accumulation,combining with static and fine characterization of the passage system.Finally,the dominant directions of hydrocarbon migration are pointed out.
