摘　　要：产量递减分析的关键和难点,一方面是产量递减方程的建立及其参数的求解,另一方面是要求方程的变化范围和覆盖面要广,即具有一定的通用性。为此,在总结已有的研究成果基础上,提出了一种新的广义产量递减方程,并对特征参数进行了分析。指出当a=0或a=m^2D_i^2/4时,该递减方程可转化为Arps递减方程;当和时,该递减方程可转化为反正切微分分布产量递减方程;当时,该递减方程可转化为修正的胡允栋递减方程;当时,该递减方程可转化为FWG3产量递减方程。在以上研究的基础上,提出了该递减方程的求解方法。后经实例应用,效果很好,值得推广应用。The key and difficulty for production decline analysis are： （1） the establishment of production decline equation and parameter solution; （2） the requirements for wide variation range and coverage area of the equation, ie a universal equation. As a result, based on the achievements of original studies, a new generalized production equation was presented, and characteristic parameter was analyzed. If a=0 or a=m^2Di^2/4, the decline equation can be transformed into Arps decline equation. If m=1 and Di=0, it can be transformed into production decline equation of arc-tangent differential distribution. If m=1, it can be transformed into amendatory Huyundong decline equation. If m=2/3, it can be transformed into FWG3 production decline equation. Based on the study above, the solution to the decline equation was presented. After being applied in the case, its effect is good and it deserves popularization.
