摘　　要：目前,在处理一点法试井资料时,取函数α为定值0.25来计算气井的无阻流量,其结果与修正等时试井有很大的偏差。针对上述问题,充分利用了一点法测试不稳定阶段的数据,在理论上推导出了α与有关参数的关系式,利用这个关系式能计算出α的准确值,从而得出气井准确的无阻流量。应用实例证明了新方法是比较可靠的,为以后计算气井无阻流量和开采配产作业提供了准确的依据。When processing of data from single-point test, the value of α is generally taken by 0.25 for calculating the open flow potential of gas well, and the result is far from that from modified isochronal test. This paper deduced the relationship between α and other related parameters using data from single-point test in non-steady state, by which the accurate open flow potential of gas well is then gained for its proper value of α The case study indicates that such a method is more reliable than before, and provides more precise bases for further open flow potential estimation and proration measures implementation.
