摘　　要：根据凝灰质砂岩骨架导电的特点,建立凝灰质砂岩有效介质HB电阻率模型,将含水饱和度方程与多条测井曲线响应方程联立,应用最优化方法求解岩石骨架中各成分含量及含水饱和度.利用该方法对苏德尔特区的贝16井进行处理,并将处理结果与薄片分析及试油成果进行对比,结果表明,该模型适用于海拉尔盆地凝灰质砂岩的地层解释.Based on the effective medium HB resistivity models for dispersed shaly sands proposed by Berg and combined with the characteristics of resistivity for tuffaceous sands matix,the effective medium HB resistivity models for tuffaceous sandstone is derived.The equation about water saturation is joined with the response equations about some well logging curves,and then with the method of optimization the content of rock components and water saturation were calculated.By applying the method we interpreted well BEI16 in Sudert,and compared the calculated results with the real slice analysis and production test results.The result shows that the model proposed in the paper is applicable to tuffaceous sands formation in Hailer Basin.
