| 摘 要： | 气井的产能方程是求取气井无阻流量的重要方程，通常由系统试井获得。对于低渗透气藏，用常规的系统试井方法确定二项式产能方程往往比较困难。从不稳定渗流理论出发，得出了利用压力恢复资料求气井二项式产能方程的方法，由该方程还可以计算气井的排泄半径。经实例分析，本方法可行、有效。

| Abstract: | Deliverability equation of gas well is an important equation for solving absolution open flow (AOF), AOF is general obtained by method of flow after flow test, it is difficult to determine binomial deliverability equation with conventional back pressure test for low permeability gas reservoirs On the basis of transient flow theory, this paper derives method of determining binomial deliverability equation by using pressure buildup data of the well, at the same time, drainage radius of gas well can be calculated with binomial deliverability equation |
