摘　　要：介绍了近几年在天然气长输管道压缩机站工艺设计中采用的新技术:压缩机站等负荷率布站设计技术,是结合站场的实际高程和环境温度,按相同的压缩机组负荷率设置压缩机站;压缩机组备用方案定量评价方法,是采用概率分析的方法,结合压缩机站的布置情况及压缩机组可用率和储气库容积等边界条件,确定压缩机组备用方案;压缩机组适用性分析技术,是利用仿真软件模拟压缩机工作曲线,分析压缩机组和管道特性匹配后的实际工况。在西气东输一线、二线等管道工程中的应用表明,这些技术可以明显降低管道工程投资,提高管道运行的经济性。New technologies used in the process design of compressor stations for long-distance gas pipelines in recent years are introduced.The design technology of equal load rate station arrangement for compressor station refers to the arranging of compressor stations according to same load rate for same compressor unit in combination with actual elevation and ambient temperature of the station.The quantitative evaluation method for compressor unit alternatives refers to the method for determination of compressor unit alternatives with probability analysis method in combination with the layout of the compressor stations and the availability of the compressor units and gas storage volume and other boundary conditions.The compressors unit applicability analysis technology is to analyze the actual working conditions of compressor units after matching with pipeline characteristics by using simulation software to simulate the compressor operating curve.The application of these technologies in the first West-to-East Gas Pipeline and the second West-to-East Gas Pipeline have significantly reduced the construction investment of the pipelines and improved the running economics of the pipelines.
