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。
In this paper, the influence of particle resistivity of sandstone, resistivity of clay particles and clay cementation index on the calculation of saturation of HB resistivity model in Taidong area are analyzed, and the reasonable range and parameter determination of these parameters in this area are determined. The water saturation of XX well in a closed coring well is explained by the effective medium HB resistivity model of the dispersed muddy sandstone. The results of the model interpretation and the closed coring analysis are compared. The comparison results show that the calculated water saturation Compared with the closed coring calculation, the saturation error is small, reasonable and reliable, and can be used in logging interpretation of water saturation in the Taidong area.
