摘　　要：在实际应用"一点法"产能公式时,往往算出的气井无阻流量和产能测试算出的无阻流量相差比较大,并且是偏大还是偏小都无规律可循。究其原因,是因为即使是同一气藏中不同的气井都有不同的α值,并且差别比较大,如果使用一个固定的α值,势必会引起极大误差。在经过关井进行压力恢复测试并了解地层参数的情况下,可以求出α值,再利用"一点法"产能公式计算气井无阻流量就比较准确。The open flow potential from one-point method for calculation of gas well deliverability tends to be larger than that from the deliverability equation,and the result is irregular.The study shows that only giving one value of alpha in calculation must cause big error.The alpha value can be obtained by shut-in well pressure build-up test and available formation parameters,thus the open flow potential of a gas well given by one-point deliverability equation is more accurate.
