摘　　要：目前含水饱和度计算是油气储集层定量评价的核心,B区块N组储层岩性复杂,以砂岩、砂砾岩为主;储层含泥重,泥质含量在8%~42%,泥质的附加导电性强。根据油田实际地质情况优选了印度尼西亚模型,在岩石物理实验基础上,分岩性确定了不同的岩电参数a、m值,研究了混合液电阻率的确定方法,来求取目前含水饱和度。该方法经检查井实际资料处理验证,解释效果好,结果可靠。The calculation of current water saturation is the core of quantitative evaluation of the hydrocarbon reservoir. The reservoir lithology is complex of N Formation in B block, mainly sandstone and glutenite;the reservoir has high shale content, which ranging from 8% to 42%. The added conductivity is strong. According to the actual geological conditions of the oil field, the Indonesia model is optimized, on the basis of petrophysical experiment, different petroelectric parameters a/m are given by distinguishing the lithology, the determination method of the resistivity of the mixture was studied, then to calculate the current water saturation. The method has been verified by the actual data processing of the inspection Wells, and the interpretation effect is good and the result is reliable.
