摘　　要：气井二项式产能方程是计算气井无阻流量的常用方法,其关键在于确定系数值。分析推理得出了一种简单的方法来确定气井二项式产能方程,不需要地层静压,只通过井底流压和产气量的数据,利用线性回归法,即可建立二项式产能方程,同时还能够反推确定地层压力。在塔里木盆地牙哈凝析气藏的实际资料计算结果表明提出的方法计算结果可靠。具有较为广阔的应用前景。The binomial deliverability equation is the ordinary method of calculating the gas well′s open-flow capacity, the key is determining the coefficient. A gas well′s binomial deliverability equation is derived from a simple new method, no static formation pressure will be taken into consideration, based on the data of bottom hole flowing pressure and gas production rate only, as well as linear regression, the binomial deliverability equation can be established, meanwhile, the formation pressure can be determined, too. The result is accountable after practical calculation to the gas condensate reservoir at Yaha, Tarim basin.
