摘　　要：含油饱和度模型实用参数的确定影响所建模型的应用效果，因此模型参数的确定方法在建模过程中至关重要。由于电阻率测井值受井眼环境、测井分辨率等影响而与岩心电阻率之间存在差异，不能直接应用岩心电阻率测量值进行参数优化，因此采用测井刻度岩心电阻率方法确定有效介质电阻率模型参数。应用该模型计算含水饱和度的相对误差平均为5．2％，符合储量规范的误差（8％）要求。Due to the practical parameter determination of oil saturation model influences the utilized effects of the established model, so the determining method is very important for the modeling process. Because of the influences of the borehole surroundings, well logging resolution and so forth, there are a certain difl＇erences between the resis- tivity logging value and core resistivity, thus the measured value of the latter cannot directly applied to optimize the parameters. Therefore with the help of the calculating method of the core resistivity by well loggings, the resistivity model parameters can be determined for the effective media. The average relative error of the water saturation calcu- lated by the model is 5.2% and meets the error requirements （8%） of reservoir regulations.
