摘　　要：计算和分析地层的含油饱和度是准确评价地层情况的有效途径。本文针对建立方程计算泥质砂岩储层中的饱和度这一问题进行了研究，通过对比阳离子交换模型和有效HB电阻率介质模型，介绍了它们的研究原理，并按原理对模型的计算方程进行了推导，再按照各模型的计算方程分别计算出了实际资料中的含水饱和度，并与岩心分析得出的含水饱和度Sw进行对比，来讨论和评价模型的实际应用效果。Calculation and analysis of oil saturation are the effective ways to evaluate the formation accurately.How to establish the equations to calculate the saturation of argillaceous sandstone reservoirs is studied in the paper.Cation exchange model is compared with the effective HB resistivity media model.The calculation equations of the models are derived from the principle.Then actual water saturation Sw is worked out with the equations for each model which is compared with that of core analysis.Finally the data are used to discuss and evaluate the practical effect of the model.
