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。

Abstract: When processing of data from single-point test, the value of αis 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.

Key words: single-point test, modified isochronal test, open flow potential, method
