          摘要:
          低孔隙度低渗透率的储层中孔隙结构比较复杂,地层水矿化度未知,利用电阻率区分流体性质困?#36873;?#20171;电扫描测井仪器采用铰接式极板,有4种不同的频率,具有不同的探测深度,最深可达到4 in,能够测量地层介电常数。油气和水的介电常数差异很大,介电扫描测井通过反演得到的介电常数计算侵入带内的含水孔隙度,与常规测井或核磁共振测井得到的总孔隙度对比得到侵入带内的油气饱和度。介电扫描测井技术除可以得到地层的含水孔隙度外,同时能得到反映岩石结构的参数m、n或者阳离子交换能力。介绍介电扫描测井的基本方法、工作原理和应用。对长庆油田介电扫描测井实例进行了分析,测井解释结果与试油结论一致。
          Abstract:
          It is difficult to determine fluid types in low porosity and permeability reservoirs with very complex pore sizes and unknown water salinity. Dielectric scanner logging tool uses gemel poles with 4 kinds of frequencies, and has different probing depths with 4 in deepest depth, and can measure formation permittivity. Permittivity difference of hydrocarbon and water is bigger. Water porosity of the invaded zone is estimated through the permittivity by inversion, then hydrocarbon saturation is got by comparing the total porosity from conventional log or NMR log. Dielectric scanner logging technology not only acquires formation water porosity, but also get m,n reflecting rock structure and cation exchange capacity. Introduced are the basic method, the principle and application of dielectric scanner logging. Analyzed are cases of dielectric scanner logging in Changqing oilfield, and the interpretation results agree well with testing results.
