对Webull产量递减方程的修正与完善

Amendment and Improvement for Webull Production Decline Equation

针对Webull产量递减方程在0<b<1时不存在初始递减率的问题,提出了修正后的标准方程及其待定参数的计算方法。修正后的递减方程不仅可描述产量为单调递减时的变化,而且也可描述产量为单调递增或为一恒定常数时的变化问题。经实例应用,效果很好。

As for the problem-no initial decline rate existed in Webull production decline equation when b is ranged from 0 to 1, the standard equation and calculation method of uncertain parameters were presented. The amended equation is able to describe the production not only when the decline rate shows monotone decreasing but also monotone increasing or an invariable constant. After being applied in the field, it has a good effect.
