在分析气井稳产期单井平均产能和无阻流量关系的基础上，结合单点测试计算无阻流量方法，导出了计算凝析气井产能经验公式。实测计算结果和传统试井分析方法计算结果吻合较好。方法简单实用，易于掌握。 Based on the analysis of the relationship between the single well average capacity and the unobstructed flow in stable production period of gas well, the formula of calculating productivity of condensate gas well is deduced based on single point test. The calculated results are in good agreement with the traditional well test methods. The method is simple and practical, easy to grasp.
