摘要
用径向电阻率的变化特性导出自由水饱和度,并从地质角度出发,推导出河南油田测井解释中定量判别水淹层级别的条件。此方法用于南阳地区水淹层的解释,其符合率高于单纯用阿尔奇公式导出的储层水淹状况。
Free water saturation is derived from the variations of radial resistivity. Then,from the view point of geology, the conditions for quantitatively identifying watered-out zones in Henan Oilfield is deduced' The interpretation results of Nanyangwatered-out zones by differential method coincide much better than that only byArchie equation.
