摘　　要：针对井下水淹层识别效率低,精度差的不足,在对水淹层的形成原理和特性进行分析的基础上,对自然电位基线偏移法、电阻率值识别法、曲线重叠法识别水淹层的原理和应用情况进行了分析。结果表明采用新的水淹层定量识别方法能够快速、高效对井下水淹状态进行判断,为油田开采技术方案的确定提供技术支持。In view of the shortcomings of low efficiency and poor accuracy of downhole waterflood layer identification,the principles and applications of the natural potential baseline offset method,resistivity value identification method and curve overlap method for identifying waterflood layers were analyzed based on the analysis of the formation principle and characteristics of waterflood layers.The results show that the new method of quantitative identification of water flooding layers can be used to determine the water flooding status of a well quickly and efficiently,which can provide technical support for the determination of the technical solution of oilfield exploitation.
