摘　　要：板桥油田低阻油层测井解释一直是影响测井解释符合率的主要原因之一,也是常规测井评价的一大难点问题。本文通过地质研究、岩芯分析、测录井、试油等资料,分析了低阻油层类型、成因,探索利用岩性、电性、物性曲线的匹配特征,评价岩性低阻油层;利用侵入校正程序反演原状地层电阻率,评价咸水泥浆测井造成的低阻油层的低阻油层测井解释方法,充分挖掘低阻油层潜力,在实际生产中,见到较好的应用效果。Logging interpretation of low resistivity reservoir in Banqiao oilfield has always been one of the main factors affecting the coincidence rate of logging interpretation,and it is also a difficult problem in conventional logging evaluation.Based on the data of geological research,core analysis,logging and oil testing,this paper analyzes the types and causes of low resistivity oil reservoirs,explores the application of matching characteristics of lithologic,electrical and physical property curves to evaluate lithologic low resistivity reservoirs;uses invasion correction program to inverse the resistivity of undisturbed formation,evaluates the logging interpretation method of low resistivity oil layer caused by salt cement slurry logging,and fully excavates the low resistivity reservoir logging interpretation method In the actual production,good application effect has been achieved.
