摘要
将节点系统分析方法引入凝析气井的动态分析，并编制了完整的计算软件。该方法根据生产实际对所需参数的要求和分析问题的不同，可将节点设在井口、井筒或井底。应用该方法对苏桥凝析气井进行了计算分析，根据计算结果及节点分析动态曲线确定了气井的最大稳定产能和最佳匹配压力，并对油管直径、井口压力、地层压力等因素进行了敏感性分析。
In this paper, a nodal system analysis method is introduced into dynamic evaluation of gas condensate well performance, and a relevant complete computer program is composed. According to the requirements of parameters in production and practical cases, the nodes may be set at well head, wellbore or well bottom. As an example, SUQIAO gas condensate well performances are calculated and the maximum stable production rate and optimum matching pressure are determined by the calculated results and nodal behavior curves. Furthermore,sensitivity analysis is carried out for selecting wellbore radius, wellhead pressure, and reservoir pressure.
