韩清忠等：用常规电阻率测井资料确定水淹层的剩余油饱和度，测井技术，１９９６（５）２０，３５１～３５５。油田综合含水越来越高，利用电阻率测井资料确定地层的剩余油饱和度变得非常困难。针对这一问题，提出了确定地层水电阻率和含油饱和度的方法。①利用已知的地层水分析资料，采用井下自然电位刻度，井间对比和双自然电位方法来求准地层水混合液电阻率，然后利用相邻井相同地层的电阻率对比方法求含水饱和度。②利用电阻率的横向探测特性，避开阿尔奇公式中ｍ、ａ选择上的困难，采用横向法计算水淹层目前的含水饱和度。利用以上方法处理几十口水淹油井的测井资料，得出比较满意的结果。
Han Qingzhong et al .: Determine remaining oil saturation of flooded layer with conventional resistivity log data, Well Logging Technology, 1996 (5) 20, 351-355. The comprehensive water cut in the oilfield is getting higher and higher. It is very difficult to determine the remaining oil saturation of the formation by resistivity logging data. In response to this problem, a method to determine formation water resistivity and oil saturation has been proposed. (1) Using the known formation water analysis data, the downhole natural potential scale, crosswell comparison and double natural potential method are used to determine the resistivity of formation water mixture, and then the resistivity of the same formation in adjacent wells is used to determine the water saturation . (2) By using the transverse resistivity detection characteristics, we avoid the difficulty of choosing m and a in the Archie formula and calculate the current water saturation of the flooded layer by the transverse method. Using the above method to process well logging data of dozens of water flooded wells, we get satisfactory results.
