建立综合判别数学统计模型，利用回归这算得出的残差平方和大小比较作为某个具体油田的递减类型判别标准，从而使递减类型的判刑简单迅速，更加科学，更加切合实际。并得出结论：调和递减类型不多见，指数递减、双曲递减和直线递减计算结果与实际资料误差比较接近，可以应用计算方便的指数递减作为编制方案的产量预测模型。 The establishment of a comprehensive mathematical model of discrimination, the use of regression to calculate the size of the residual sum of the size of the comparison as a specific field of decline in the type of discrimination criteria, so that the type of sentence is simple, rapid, more scientific and more realistic. It is concluded that the types of hypomorphic decrease are rare, the exponential decrease, the hyperbolic decrease and the linear decrease are close to the actual data error, and the exponential decay calculation can be used as the yield prediction model.
