摘　　要：不稳定试井和生产测井都是目前油气田动态检测的重要手段。相态重新分布使不稳定试井特征曲线异常,给凝析气井试井解释带来困难,但同时也给异常复杂的试井特征曲线分析提出了新的问题。通过对凝析气井不稳定试井特征曲线和测试资料进行分析及对比研究,阐述了受相态重新分布影响的试井特征曲线与生产测井结论的联系,能够对相应射孔层位的产出做出定性判断,为凝析气井生产动态监测提供一种新的参考方法。The transient well test and production logging were the important methods for dynamic inspection of oil and gas fields.Phase state redistribution induced abnormality of transient well test characteristic curve and the difficulty for well test interpretation of condensate gas wells,at the same time it also raised new problem for analyzing the well test characteristic curve.Through analyzing and contrasting the transient well test characteristic curve and the well test data,this article explains the relationship between transient well test characteristic curve influenced by the phase state redistribution and production logging result,it provides a qualitative judgement to the production of perforation zones and also provides a new reference method for dynamic inspection of condensate gas wells.
