摘　　要：针对苏里格气田主力储气层盒8段,根据其储层特性,开展了环境扫描电镜、恒速压汞和润湿吸附等一系列岩心试验,从微观上分析了引起储层伤害的因素,同时对外来液体侵入储气层而造成伤害进行了分析研究,弄清楚了盒8段储层的微观特征及储层伤害的微观机理,对下一步储层的改造和气田开发技术政策的制定具有重要的指导意义。In allusion to the feature about the reservoir 8 of Su Lige,this paper makes a series of experiments of electron microscope scanning,constant speed pumping mercury and wetting absorption,etc.Factors of the damage are analyzed from the microcosmic aspect,Besides,the damage caused by extraneous fluids is analyzed.This paper finds the microcosmic feature and the microcosmic mechanism of damage to the reservoir 8.It can be significante guide for gas field development and reform strategy.
