摘　　要：气井出现载水现象后,井筒中流体的流动状态和介质分布将变得复杂,其生产动态监测更为困难。在介绍新的持气率计(GHT)测量原理和特点的基础上,分析了持气率计在气井生产动态监测中主要用途,提出了综合传统密度计和新型持气率计测井资料分析井下流体性质、流动状况及判断气井载水的方法;根据载水气井不同深度段的特点,提出了载水气井的解释模型。实例表明,应用持气率资料有利于提高产气剖面解释的准确性。After water is carried in gas wells,status of fluid flow and medium distribution become more complicated,its production performance detection will be more difficult.On the basis of introducing the working principle and characters of newly made Gas Holdup Tool(GHT),the usage of GHT in detecting the gas well production performance is analyzed.Methods are provided for analyzing fluid property,flow status and judging water carriage in gas wells by integrating the logging data obtained from traditional densimeter and the new GHT.Based on the characters of different depth in water carried gas wells,a model is established for interpreting the water-carried gas wells.Examples indicate that application of gas holdup data is beneficial for improving the precision of gas producing profile interpretation.
