| 摘 要： | 对于低孔低渗、泥质含量较高的泥质砂岩储层,我们提出了一种新的模型来反演地层水电阻率和含水饱和度。它首先对阿尔奇公式进行了泥质校正和粘土附加导电校正,同时采用变m指数部分补偿了低孔低渗的影响,然后利用得到的模型通过规划求解的方法同时反演得到了含水饱和度和地层水电阻率。计算结果与试油资料的对比证实了该方法的可行性。

| Abstract: | A new model is proposed to determine the formation water resistivity and water saturation of shaly sandstone reservoirs with low porosity, low permeability an d high shale content.It introduces shale calibration to Archie equation,involves additional conductivity of clay,and adopts alterable m parameter to diminish the influence of low porosity and low permeability in some extent.Then formation water resistivity and water saturation can be obtained by applying program solving method to this model.It is prov... |
