摘　　要：薄油层识别与评价的困难在于测井仪器的垂向分辨率低，测得的曲线不能真实反映薄油层的物理特性，解决此问题的方法之一是采用数据处理方法提高常规测井曲线的纵向分辨率。文中采用分辨率匹配法提高测井曲线纵向分辨率，以高分辨率的微球聚焦电阻单曲线作匹配曲线来提高深三侧向电阻单曲线的分辨率，并利用分辨率匹配法处理了大庆油田Ｊ２７井的测井资料，结果表明：深三侧向测井曲线经高分辨率处理后的电阻车更接近岩心分析的电阻率。The difficulty of thin bed identification and evaluation lies in the lower vertical.resolution of logging tools.Methods to solve this problem are to increase the vertical resolution of conventional logs by data processing.In this paper,the resolutionmatching method is applied to enhance the resolution of a deep lateral resistivity log, by taking a microresistivity as a matching curve.The data from J27 well in Daqing field is processed by the resolution - matching method and results show that the resistivities are consistent with the core-analysed one.
