摘　　要：常规电阻率测井因受其纵向分辨率的局限 ,难以确定其真电阻率 ,无法准确划分层厚在 2m以下的薄层。综合分析薄层电阻率测井与常规微电阻率测井、双侧向电阻率测井及孔隙度测井资料 ,对于提高砂泥岩储层 ,特别是薄油气层的解释精度有重要作用。给出了几个利用薄层电阻率测井识别薄油气层的实例 ,介绍了薄层电阻率测井在油气层识别中的解释分析方法。Due to the limitation of vertical resolution of conventional resistivity log, it is not able to identify thin bed thiner than 2 m and determine its true formation resistivity. Comprehensive analysis of TBRT, conventional micro resistivity DDL and porosity logs is important in evaluating thin sand and shale sequence as well as improving its interpretation accuracy. Given in this paper are some application examples and methods to identify thin oil/gas reservoir by using TBRT, the result of which is desirable.
