摘　　要：天然气井绝对无阻流量是反映气井潜在产能的重要指标,是科学合理确定气井产量的重要依据。一点法试井是一种快捷有效的确定气井产能的方法。文中利用一点法稳定试井理论模型,对台南气田稳定试井资料进行统计分析并得出适合台南气田的一点法经验公式。利用一个稳定点测试资料即可确定气井产能,同时进行误差分析并校正。经验证,该方法可作为现场修正等时试井的重要补充方法来监测产能变化情况。Absolute open flow of natural gas well is not only the important indicator to reflect potential productivity, but also the foundation to determine reasonable production rate. One point method deliverability testing is a quick and effective method to determine gas well productivity. Based on one point method systematic well testing theoretical model, the systematic well testing data of Tainan Gasfield are analyzed, and the one point method empiric equation suitable for unconsolidated gas reservoir is obtained. After Error correction of the empiric equation, this method can be used to monitor productivity changes.
