摘要： 根据以往塔里木盆地计算气井产能的常用方法,对塔里木油田高压气井产能测试资料进行了分析研究,讨论了拟压力形式分析方法与压力形式分析方法之间存在的关系，建立了高压气井拟压力计算无阻流量与压力平方计算无阻流量的经验关系，给出了适合于高压气井的拟压力及压力形式一点法无阻流量计算公式。通过大量的实例计算，证实该方程计算结果与产能测试回压试井、等时试井、修正等时试井)数据分析结果一致,计算结果可靠适用，能正确预测塔里木盆地高压气井的生产动态,指导高压气井的合理生产。

Abstract: Using the conventional estimation methods, this paper analyzes the deliverability test data of high-pressure gas wells in Tarim field,discusses the relationship between pseudo-pressure analysis and pressure analysis methods, and develops empirical correlation between open-flow potential estimation in forms of pseudo-pressure and square pressure for high-pressure gas wells, providing a new single-point open-flowpotential equation suitable for both forms. The estimations from many cases show that the results from the equation are accordant with those fromthe productivity test data analyses such as conventional test, isochronal test and modified isochronal test. This equation is practical and reliablefor forecasting the production performance of high-pressure gas wells, and helpful to guarantee the reasonable development of the gas wells.

Key words: Tarim basin, gas well, productivity, equation, pressure, openflow capacity
