摘要: 在阿尔奇公式基础上推导出利用阵列感应测井资料计算含水饱和度的方法。该方法充分利用了阵列感应不同探测深度的电阻率比值,避免了孔隙度计算,增加了直接测量参数的应用,有效地减少了物性参数计算带来的误差和岩性带来的影响,提高了含水饱和度计算的精度,实现储层流体识别的定量评价。Abstract: Based on the Archie formula,we obtain a new method to calculate water saturation by using array induction logging data.By taking the full advantage of the different resistivity ratio,avoiding porosity calculation and increasing the applications of direct measure parameters,to some extent,we effectively reduced the impact of physical parameters calculating and lithology,improved the accuracy of water saturation and achieved the quantitative evaluation of reservoir fluid identification.
