摘　　要：为了进一步提升中亚和国内天然气管道站场设计水平,从设计规范和通用做法着手,基于中亚与国内天然气管道站场3个比较具有代表性的设计案例,对压气站进出站ESD阀门、越站管道和清管设施的设置,压气站放空立管的设置以及清管站(区)清管污物收集系统进行了设计差异分析,并指出了各自的优势和不足。结果表明:中亚压气站进出站ESD阀门、越站管道和清管设施的布置相对国内安全性更高,进出站ESD阀门的设置位置较国内合理,但不便于统一管理;国内放空立管的高度和结构设计优于中亚压气站放空立管设计;中亚清管污物收集系统相对国内具有更强的纳污能力,操作更灵活,但清管污物收集程序比较复杂,操作风险高。To further improve the station design of gas pipelines in Central Asia and China, 3 representative design cases（configuration of inlet and outlet ESD valves, by-pass pipeline and pigging facilities at of compressor station, configuration of vent stack in compressor station, and sewage collection system in pigging station/district） are analyzed for their differences from the aspects of design specifications and general practices. Their advantages and disadvantages are pointed out. The results show that, the security of inlet and outlet ESD valves, by-pass pipeline and pigging facilities at the compressor station in Central Asia case is higher, and the inlet and outlet ESD valves are set at a more reasonable position but they can not be managed uniformly; the height and structural design of vent stack in China case are superior to the Central Asia case; the pigging sewage collection system of Central Asia case is more capable and flexible, but the collection procedure is relatively complex with high operational risk.
