摘　　要：针对储气库注采井在生产过程中由于压力流量控制不当或紧急情况下放空气量过大带来的生产安全问题,提出一种新型限流音速喷嘴,简化天然气流量控制工艺,实现对气体流量的精确控制。采用CFD模拟软件建立喷嘴的三维数值模型,模拟高压气体通过喷嘴的速度场、压力场和温度场分布特征,筛选出一种最佳新型喷嘴结构。将新型喷嘴应用于文96储气库,根据气体通过音速喷嘴的流动特性,形成新型喷嘴流量控制工艺和技术。现场应用结果表明:限流音速喷嘴实现了储气库注采气工艺中天然气安全泄放控制、采气工艺中对采气井气量的控制以及流量控制等,有效降低了储气库系统能耗,提高了系统整体效率,保障了系统安全、高效、平稳运行。In order to solve the problems caused by improper pressure and flow control or gas blowdown in emergency,a new sonic nozzle structure was developed to optimize natural gas control process,which could accurately control the mass-flow.The CFD simulation software was used to establish the physical and mathematical models of the sonic nozzle.The results showed that the new critical venturi nozzle could be used in the safety control of natural gas venting and the control of gas production.It reduced energy consumption in gas storage system efficiently,which could ensure the safe and stable operation of the system.
