确定苏里格气田西区低阻气层的成因机理,可更好地指导测井气层识别.依据苏里格气田西区岩心压汞、扫描电镜和测井资料,从储层目的层段电性特征研究入手,结合目前国内外对低阻油气层成因的最新认识,对该地区低阻气层进行了深入分析.分析认为该区储层岩性细及微孔隙结构发育、黏土矿物附加导电性、高不动水饱和度是造成苏里格气田西区电阻率低的主要原因.这为测井识别低阻气层提供了科学依据,准确评价此类储层具有重要意义.%It can better guide log interpretation to confirm the causing mechanism of low resistivity gas zone in the Wast of Sulige Gasfield. Based on the core mercury intrusion, SEM(scanning electron microscope) and logging data in the west of Sulige Gasfield, starting from the electrical characteristics of objective interval of reservoir, combined with the domestic and overseas latest understanding of the causes of low resistivity reservoirs, the low resistivity gas reservoir carried out in-depth analysis. Analysis believe that reservoir fine lithology and micro-pore structure development, clay minerals additional conductivity, high immobile water saturation are the main causes of low resistivity in the west of Sulige Gasfield. This provides a scientific basis for identifying low resistivity gas reservoir, and accurately evaluate such a reservoir is of great significance.
