摘　　要：利用常规测井资料确定含水率，是测井解释的一个难点。以含水率直线模型为基础，分析了含水率解释过程中复杂的影响因素，认为剩余油饱和度、原油粘度和油层渗透率的变化对含水率的解释精度影响较大。这是因为含水率是由油层各种性质所决定的综合性参数，其解释并不是一个单纯的测井计算问题，其精度取决于基础方程的可靠性以及基础参数选取的准确程度。Determination of water Cut by conventional logging technique is one of troubles in log interpretation. Complex affecting factors in the log interpretation process are analyzed with the straight line model of water Cut as a basis. It is considered that the change of remaining oil saturation, oil viscosity and reservoir permeability give more serious effects on the precision of log interpretation. This is because water Cut is a comprehensive characteristic including all petrophysical properties of the reservoir, thus its interpretation is not a logging calculation only; the precision will be determined by the reliability of the basic equation used and the accuracy of the basic parameters selected.
