摘　　要：吴起胜利山区长6油层组电阻率接近临近水层,常规测井识别方法已难以将其有效区分。本文收集了大量的研究区测井资料和地质资料,绘制并分析了相关成果图,以岩心分析化验数据为佐证,将该区低阻油层成因界定为储层物性变差、孔隙结构复杂、黏土矿物和高伽玛物质的影响。适合本地区的测井识别方法是交会图法和重叠图法。Chang6 low resistivity oil reservoir is Obviously in Shenglishan area of Wuqi oilfield. It is difficult to distinct oil and water. This paper collects rich data in logging and geology . Production figures are carefully plotted and researched. It was found that oil and water zones in low resistivity oil reservoir in Shenglishan area are affected by changes of reservoir physical properties, changes of reservoir hole structure, clay minerals and abnormality of natural gamma. According to actual conditions of Shenglishan, the interpretation methods such as intersections , movable water analysis are put forward.
