低孔低渗储层具有低孔隙度、低渗透率非均质性强等特点，其岩电参数特征与常规储层存在显著的差异；因此储层含水饱和度的计算是测井评价的一个难题。对南海西部海域大量低孔低渗样品的岩电实验结果进行分析研究，建立了利用测井曲线反演地层胶结指数m值与含水饱和度的方法。实际计算结果表明，由算法反演得到的胶结指数m值与岩心岩电实验结果很接近，因此可证明利用算法计算得到低孔低渗储层含水饱和度是可靠的。

Low porosity and permeability reservoirs with low porosity and low permeability characteristics of het-erogeneity, the rock electrical characteristics with conventional reservoir parameter exists significant difference;therefore calculating the reservoir water saturation is a problem of logging evaluation.Base on analyzing rock elec-tricity experiment results of a large number of rock samples, established the inversion formation cementation expo-nent m value and resistivity response equations of water saturation using the logging curve.Actual calculation re-sults show that the m values obtained in this paper by the inversion algorithm is very close with the rock electric ex-perimental results, so to prove that the algorithm presented to calculate the low porosity low permeability reservoir water saturation is reliable.
