摘要
对于产量随时间任意变化的情形,本文用折线代替产量变化曲线,给出一种简明而又准确的用于进行压力降落分析的方法。
A theoretical development is presented in this paper which provides a concise and accurate method of handing the drawdown analysis for variablerate case. In this mothod the curves of production variation are replaced by broken-lines istead of a steped lines. Eq (6) is deduced to analyse pressure drawdown performance, the X in Eq (6) is given by Eq (7), (14) and/or Eq (19) for one, two and/or three line-segments respectively.
