摘要(Abstract)：

通过对研究区块岩心的扫描电镜、X衍射、黏土矿物分析、阳离子交换容量测量、铸体薄片及水分析等资料的研究发现,高束缚水饱和度是造成苏77山2~3段低电阻的根本原因,高矿化度地层水是直接原因,导电矿物影响微弱.由于低阻气层在电性曲线上与气水层、水层差异不明显,应用常规测并技术和解释方法很难有效识别,在解释过程中容易漏掉气层.提出用孔隙度重叠法、阵列感应测井法和束缚水饱和度法进行低阻气层的识别,与常规测井解释方法相比,解释精度大幅度提高,并将上述方法应用到苏里格气田中,取得了显著效果.

关键词(KeyWords)： 低阻气层;高束缚水饱和度;高矿化度地层水;孔隙度重叠法;束缚水饱和度法
