摘　　要：通过对岔河集油田水淹层影响因素的分析,以及对水淹后储层岩性、物性、电性和含油性变化特征的研究,提出了利用自然电位和可变水法2个计算水淹层混合地层水电阻率的方法,给出了利用这2种方法的应用实例。藉此求取的剩余油饱和度计算精度有效满足了岔河集油田的开发需要。Proposed are two methods, one is the SP response equation and the other is the variable mixed formation water resistivity algorithm, for calculating the mixed formation resistivity in the water flooded zones on the basis of analyzing the factors influencing the water flooded zones in Chaheji oilfield and studying the lithology, physical property, electrical property and oil-bearing in the water flooded reservoirs. Given are the two method＇s application examples. The accurate remaining saturation calculated with the above methods meets the requirment of Chaheji oilfield development.
