涩北气田位于柴达木盆地东部,距格尔木市236 km,平均海拔2 750 m。由于气田和周围用气经济发达地区均存在海拔差异或有高山阻隔,气田长输管道的起终点存在高程差或沿线要翻越高点。研究沿线地形起伏的高差对气田输气管道的影响,对保证管道的输气能力和下游用户的用气平稳都有十分重要的意义。 Sebei gas field is located in the eastern Qaidam basin, 236 km from Golmud City, with an average elevation of 2 750 m. Due to the differences in altitude or the isolation of mountains due to the gas economically developed areas in and around the gas fields, the elevation of the long-distance pipelines in the gas field may be high or the high point should be crossed along the line. The research on the impact of elevation difference along the terrain on the gas pipeline in the gas field is of great significance to ensure the gas transmission capacity of the pipeline and the gas consumption of downstream users.
