摘　　要：根据岩心常规薄片、物性和压汞等实验分析资料以及测井解释结果,对威远气田震旦系灯影组储层的岩石学特征、物性特征、孔隙类型、孔隙结构特征以及储层分布特征进行分析与研究,研究认为灯影组主要的成岩作用为压实作用;储集空间以裂缝孔洞型为主,次为洞穴;储集体为叠置的透镜体,由致密岩分隔组合成复合透镜状白云岩储层。综合各项物性参数评价该储层为II类储层。According to the conventional thin section of core, the physical properties and the analysis of mercury and other experimental data and the well log interpretation results ,we do the analysis and researches about the rock characteristics ,physical properties ,pore type ,pore structure and reservoir distribution characteristics of the Sinian Dengying formation in the Weiyuan gasfield, the research shows that master control factors are diagenesis; in the main the reservoir space are cavity-type cracks followed by the cave ;the reservoir is the overlay lens, combined separately into a dense rock with a composite lenticular dolomite reservoir.The reservoir of Weiyuan gas field is estimated to be the second level reservoir according to the physical property parameters.
