摘要:
低孔隙度低滲透率的儲層中孔隙結構比較復雜,地層水礦化度未知,利用電阻率區分流體性質困難。介電掃描測井儀器采用鉸接式極板,有4種不同的頻率,具有不同的探測深度,最深可達到4 in,能夠測量地層介電常數。油氣和水的介電常數差異很大,介電掃描測井通過反演得到的介電常數計算侵入帶內的含水孔隙度,與常規測井或核磁共振測井得到的總孔隙度對比得到侵入帶內的油氣飽和度。介電掃描測井技術除可以得到地層的含水孔隙度外,同時能得到反映巖石結構的參數m、n或者陽離子交換能力。介紹介電掃描測井的基本方法、工作原理和應用。對長慶油田介電掃描測井實例進行了分析,測井解釋結果與試油結論一致。
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.
