| 摘 要： | 指数式方程作为一种产能试井资料整理模型,除了众所周知的是一经验公式、适用于产量范围小、外推无阻流量误差大等缺点外。笔者在整理陕北气田的修正等时试井资料过程中,还发现修正等时试井和等时试井资料均不宜用指数式方程整理。本文将分析其原因,并在此基础上提出一种利用等时或修正等时试井资料间接获取指数式产气方程的方法。

| Abstract: | The exponential equation is regarded as a model of sorting out the deliverability testing data. Besides that it was known as a experience formula,applying to a little range of production and having a large error in extrapolation of open flow potential, recently the author found out that the exponential e- quation could not fit for sorting out the isochronal testing and revising isochronal testing data while sorting out the revising isochronal testing data in north Shanxi gas field. This paper analyzes its reasons on this basis, presents a method indirectly obtaining exponential gas production equation, using isochronal testing or revising isochronal testing data. |
