摘　　要：从不稳定渗流理论出发,扼要阐述了产量时间标准曲线的理论基础,然后提出了一种用于油井产量递减标准曲线的新算法,改进了Fetkovich算法必须解析反演导致最后解式复杂、繁琐等不足。研究表明,Arps产量递减方程是拟稳态产量公式的变形,计算速度快而准确,便于推广到其它模型和矿场应用。Starting from the theory of unsteady percolation,the theoretical foundation of rate-time typical curve is described in brief,and a new algorithm for typical curve calculation of the oil well production decline is proposed, by which the shortcomings of complexity of equation caused by Fetkovich inversion.Research indicates that Arps production decline equations are the transformation of pseudo-steady,of which the calculating rate is fast and accurate and suitable for using in other models and oilfields.
