摘　　要：处理一点法试井资料时,取口为0．25来计算气井无阻流量,其结果与修正等时试井计算结果有很大偏差。针对上述问题,利用一点法测试不稳定阶段的数据,理论上推导出a与有关参数的关系式,由此计算出a准确值,得出气井准确的无阻流量。应用实例证明,该方法为计算气井无阻流量和开采配产作业提供了准确的依据。When dealing with the data of single-point test, the result is far from that of modified isochronal test if the value of a for calculating the open flow potential is 0.25. To resolve the problems mentioned above, based on which to calculate a value accurately of using the data of single-point test during non-steady-state to deduce the relationship between a and other related parameters theoretically, the accurate open flow potential has gained. By applying examples proves that this program above provides an accurately basis for computing open flow potential and exploitation and matching production.
