摘　　要：一点法试井操作简单方便,但其测试时间短,计算结果误差较大。针对上述问题,从气井渗流理论出发,利用单井储层特征参数,推导计算气井达到拟稳态的时间,再利用该时间计算气井的产能及无阻流量。应用此方法对西部某气田的一点法测试进行了校正,结果准确可靠,为以后的开采配产作业提供依据。The single-point test is very simple and convenient, but its testing time is very short and the calculated results have many errors. To solve the problems mentioned above and based on gas well transient flow theory, this paper takes use of reservoir characteristic parameters of the single-well to deduce the time of reaching the pseudo-steady-state, then to calculate deliverability and open flow potential of gas well from this time. Applying this way to rectify testing with single point in one gas field of the westward, the result is accurate and reliable which provides an evidence for producing operation.
