【Abstract】 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.更多还原
