摘要
在作者以往研究的基础上，制作了指数递减及调和递减下年、月产量递减率关系曲线图版。阶段递减率与月份的关系是曲线关系，年递减率越小，越接近一条直线；年递减率越大，曲线关系越明显。在实际工作中，用此图版可直接查得递减率，便于在油田开发和规划工作中参考应用。
Based on [1] ed [2] in references of this paper, graphs of annual-monthly decline rate curves showing exponential decline and barmonic decline, respectively, have been plotted out, from which it can be obtained that the stage decline rate vs.months is a curve. As the annual decline rate becoming smaller, the curve is more like a straight line. As the annual decline rate getting bigger, the curve correlation is more obvious. Therefore, in practical operation, the annual decline rate derived by extrapolating the straight line of stage decline rate would invisibly overestimated the whole-year decline rate. By using this curve graph the decline rate can be read out directly. It is easy to operate for professionals engaged in oil field development.
