摘要(Abstract)：

本文从Arps,J.J.的产量递减率微分方程出发,严格推导了产量递减的三种基本规律,即指数递减、调和递减和双曲线递减.从理论上证明了产生调和递减的条件以及影响初始递减率的因素,并用图版法简便地确定了计算公式中的常数项,使本方法更便于在矿场中推广应用.文中还用大量的实际资料检验了应用产量递减曲线预测油田开发动态指标的准确性,并对油田已出现综合递减的区块进行了预测.
On the basis of the differential equation for decline of production by Arps, J.J., the paper derived the exponent decline, harmonic decline and hyperbolic decline. Conditions causing the harmonic decline to occur and the factors affecting the initial decline rate are proved theoretically. The constants in the equation are simply determined by means of plotting, thus, making this method described in the paper more applicable to the field. Adopting numerous actual data, the paper also examined the accuracy of predicting the development performance of oilfield with decline curves of production. At the same time, with these curves, the paper also predicted the performance of those developing areas in the field which have already shown composite decline of production.
