摘　　要：在对普通取心分析资料油水饱和度分布进行分区回归的基础上 ,可得出一个或多个油水关系式 ,再按照数理统计原理分别进行统计校正。统计校正扩展了分析校正的适用范围 ,只要含油含水饱和度交会点具有分区分布和线性分布特征 ,就可对密闭取心分析点或非密闭取心分析点进行校正。应用结果表明 ,与分析校正方法相比 。On the basis of zoning regression to the distribution of oil water saturation by general coring analysis, one or more relational expressions of oil and water can be derived.Oil water saturation can be calibrated by using the mathematical statistics method. This method expands the application range of the calibration of analysis methods As long as the intersection point of oil water saturation keeps the characteristics of zoning distribution and linear distribution, calibration can be made on analyzing point of sealing core drilling or non sealing core drilling Compared with analysis calibration, statistical calibration get an oil saturation consistent with actual situation in the reservoir
