摘　　要：聚合物驱中已出现含水率最低点的区块 ,采用原方法预测结果较好 ;未出现含水率最低点的区块 ,原方法预测结果误差大 .利用多元回归方法改进了原方法 ,建立了一种预测聚合物驱含水率的新的数学方法 ,并实现了自动拟合 。The original approach can get good result for polymer flood ing tracts that already showed the lowest water cut, but it has large errors for those with no occurrence of the lowest water cut. In view of this, this paper p resents an improved mathematical approach for predicting the water cut curve of polymer flooding based on the theory of multivariable regression. The improved m ethod is capable of automatic matching and can give more accurate prediction res ults than did the original method.
