摘要
证明了衰减曲线即递减指数为0．5时的Arps双曲线，也证明了衰减参数a、b、c之间始终满足b=ac的关系。提出了一种适用于时间任意取值条件下的衰减分析方法。给出了年产量预测公式及瞬时产量与年产量相互换算的近似公式。
It has proved thatthe equation of attenuation curve is a Arps hyperbolic curve which decline exponent is 0. 5 and the attenuation parameters (a, b and c) have the relation of b=ac constantly. A kind of analytical method of attenuation usedin the condition of arbitrary time is presented. The prediction formula of yearly production and the approximation formula for reduction between the instantaneous production and yearly production are also presented.
