摘　　要：自然电位测井是油层水淹后能够有效识别地层混合液电阻率信息的测井方法。研究了地层水淹后利用自然电位曲线求取地层混合液电阻率的方法,给出了自然电位曲线各种影响因素的校正方法,着重讨论了过滤电位和泥质含量对自然电位曲线的影响和校正方法。通过实际资料处理和单层试油水分析资料对比,结果表明该方法可有效求取地层混合液电阻率值。SP logging is one of logging methods which can effectively distinguish resistivity of mixed liquid in formation after oil.layer being water flooding. After that, by using SP curve to obtain the resistivty of formation mixed liquid, correction methods for various effective factors of SP logging are given, and effects of filtration potential and argillaceous content on SP logging and correction methods are discussed. Based on actual data processing and analysis data comparison for oil testing water in individual layer, the results show that this method can effectively obtain resistivity value of formation mixed fluid.
