单点法试气预测气井产能方法的补充

在气井二项式产能方程的基础上，提出了利用单点测试资料建立气井产能方程、确定气井绝对无阻流量的新方法。与以往单点测试方法相比，该方法不依赖于一个气田的α统计值(平均值)就可以得到与常规多点稳定试井法相同的气井产能方程和绝对无阻流量，也可以对气井的产能进行连续性预测。

Supplimentation to Productivity Forecast Method of Gas Wells by Single Spot Well Test Data

A new method is introduced in this paper to determine absolute open flow capacity of gas wells. This method was established , based on the binomial formula of productivity forecast of gas wells, by using single spot data of gas well testing. It doesn' t rely on the statistic a data (average value) of a field development to establish the same productivity equation of gas wells,which is identical to the equation built through conventional steady multi-spot test data, as well as to forecast the absolute open flow capacity and production profile prediction of gas wells.
