摘　　要：文章论述了双频电阻率测井的方法原理:利用频散现象来定性区分油水层;并推导出双频电阻率比值(RD/RZ)与含水饱和度的数学方程。在河南油田的地质应用表明:双频电阻率测井方法是可行的,对识别油水层效果明显。This paper discusses the method principle of dual-frequency resistivity logging,that is Using of dispersion phenomenon to distinguish between oil and water layer.Besides,this paper deduces the mathematical equation of the ratio of the dual-band(RD/RZ) and water saturation.Finally,it shows the geological application in Henan oil field.The application indicates that dual-frequency resistivity logging method is feasible,and the effect of recognizing of oil and water is obvious.
