摘　　要：本文分析了砂岩颗粒电阻率、粘土颗粒电阻率和粘土胶结指数对太东地区HB电阻率模型计算饱和度结果的影响，并确定这些参数在该地区的合理取值范围及参数的确定方法。利用分散泥质砂岩的有效介质HB电阻率模型对密闭取心井XX井进行含水饱和度解释，并将模型解释结果与密闭取心分析结果进行对比，对比结果表明，该模型计算的含水饱和度与密闭取心计算饱和度误差较小、合理可靠，可用于太东地区含水饱和度的测井解释中。The effect of sandstone grain resistivity,clay particle resistivity and clay cementation index on the HB resistivity model for saturation calculation in Taidong area is analyzed in the paper.The range and method of the parameters are determined.The HB resistivity model was used to interpret the water saturation of a sealed coring well,and comparison was made between the interpretation result and that of sealed coring. It showed that the water saturation error calculated with the model is smaller.The model is reliable and can be used in Taidong area.
