塔里木油田气井无阻流量计算公式探讨

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，组出了适合于高压气井的拟压力及压力形式一点法无组流量计算公式。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。

Discussion on Open-Flow Potential Equations of Gas Wells in Tarim Basin

Using the conventional e stimation methods,this paper analyzes the deliverability test data of high-pre ssure gas wells in Tarim field,discusses the relationship between pseudo-press ure analysis and pressure analysis methods,and develops empirical correlation b etween open-flow potential estimation in forms of pseudo-pressure and square p ressure for high-pressure gas wells,providing a new single-point open-flow potential equation suitable for both forms.The estimations from many cases show that the results from the equation are accordant with those from the productiv ity test data analyses such as conventional test,isochronal test and modified i sochronal test.This equation is practical and reliable for forecasting the prod uction performance of high-pressure gas wells,and helpful to guarantee the re asonable development of the gas wells.
