摘　　要：靖边气田高桥区主力产层马五12含气饱和度低,导致气井生产过程中,井口压力低,产水量大,气井积液情况严重,已有临界携液计算模型判识情况与实际结果出入较大,因此在筛选适合高桥区的最小携液模型基础上,对产水气井携液模型机理分析,修正气体举升过程中相关参数,建立高桥区产水气井最小携液模型,预判产水气井积液状况,优化气井工作制度,并为排水采气措施制定提供依据。Gaoqiao district gasfield main production layer Ma512 gas saturation is low,resulting in gas production process,the wellhead pressure is low,water production, gas well has been in serious condition.The critical liquid carrying model identification and the actual result discrepancy.Based critical fluid model is therefore suitable for the screening area in Gaoqiao the model of mechanism,liquid water producing gas wells with gas analysis,modify the parameters in the process of lifting,the establishment of Gaoqiao district water producing gas well critical fluid model to predict water production gas well,optimize the working system of gas well, and will provide the basis for drainage gas recovery measures.
