输导体系研究综述

The Review of Pathway system

输导体系作为联结生、储、盖、圈的桥梁和纽带,是油气运移成藏研究的关键,也是现油气运移研究的薄弱环节。输导通道宏观上主要分为储集层、断裂和不整合输导体系,且其具有独立性、时空性、复杂性、输储转化性以及运移油气时的非均一性和幕式运移等特点。储集层、断裂、不整合输导体系及各输导体系的空间组合或时空配置不同时,其输导机制和输导性能不同。在综述前人对输导体系的研究后,总结现输导体系研究的问题并提出今后研究的主要体现。

The pathway system is a bridge about source-reservoir-cap and traps,it is the key of study on hydrocarbon migration and accumulation,what's more,it's the weak link in hydrocarbon migration.the pathway includes reservoirs,faults and unconformity principally,it contains some features that is independence,space-time characteristic,complexity and transformation between pathway and reservoir.the pathway also show up heterogeneity and episodic migration if hydrocarbon is migrated in the pathway.if space combination or spatio-temporal collocation is different in reservoirs,faults and unconformity,it is also different that the mechanisms and abilities of pathway.there is review about research by predecessor and summarize about some nowaday problems,then,the embodiment about research of pathway system at afteryears is put forward.
