求取气井产能方程的新方法及其在塔河油田的应用

A New Method for Gas Well Productivity Equation and Its Applicat ion in Tahe Oilfield

气井产能方程能够直接描述流压与产量的关系,但是传统的二项式产能方程在地层压力未知或者地层压力不准的情况下无法使用。基于气井二项式产能方程,介绍了一种新的求二项式产能方程的新方法的基本原理,并应用该方法对塔河油田部分井进行了分析。

The bottom-hole flowing pressure is a dominant factor to determin e gas well's pr oductivity. Gas well productivity equation can show the relationship between flow pressure and production directly. Nevertheless, the traditional binomial produ ctivity equation can't work under the formation pressure unknown. Based on the t raditional binomial productivity equation, this paper introduced a basic princip le of a new method and applied it to analyze part wells of Tahe oilfield.
