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 ,统计校正方法可获得比较符合地层真实情况的含油饱和度 Based on the zonal regression of the oil-water saturation distribution of common coring analysis data, one or more oil-water relations can be obtained, and then statistical correction is carried out according to mathematical statistics respectively. Statistical correction expands the applicability of analytical correction. Correction of closed coring analysis points or non-confined coring analysis points can be performed as long as the intersections of oil-in-water saturations have a zonal distribution and a linear distribution. The application results show that, compared with the analysis and correction method, the statistical correction method can obtain the oil saturation that is more in line with the real situation of the formation
