摘要: 为了解决 Webull 产量递减方程在 0<b时不存在初始递减率的问题,提出了对其修正,并给出了标准方程式及其待定参数的计算方法。修正后的递减方程变化范围和覆盖面很大,它不仅可描述递减率表现为单调递减时的产量递减问题,而且也可描述递减率表现为单调递增或为一恒定常数时的产量递减问题。经实例应用,效果很好。

Abstract: In order to solve the problem that is no initialization decline rate in Webull production decline equation when b rangesfrom 0 to 1, modification of the equation is raised.The standard equation and calculated methods of undetermined parameters are presented.The modified equation allows wider range and coverage, which can not only be used to describe the production decline when decline rate shows monotone decreasing, and also describe the production decline when decline rate shows monotone increasing or is a constant value.The good effect for application of the modified equation has been obtained in Tuha oilfield.
