花土沟-格尔木输油管道是世界上海拔最高、落差最大的输油管道,管输原油凝点为33.5℃,且沿线条件艰苦、社会依托差。分析了花格管道年输量由200×104t增至400×104t时沿线各站的运行参数及启泵、启炉情况。以进站油温42℃为标准,分别计算了冬季、夏季大乌斯站在热力越站和非热力越站两种工况下管道各站的出站油温,并通过计算加热炉的功率分析启炉情况;基于原油的粘温曲线,计算得出各站间管段原油的运动粘度;由泵的特性曲线得出多台泵并联情况下泵的特性;通过计算各站进站、出站压力,得到沿程摩阻损失和各站的启泵数据。 Huatugou - Golmud pipeline is the world’s highest elevation, the largest drop in the pipeline, pipeline transportation crude oil freezing point of 33.5 ℃, and the difficult conditions along the line, depending on the poor society. The running parameters of each station along the line and the condition of pump-start and start-up were analyzed when the yearly output of the grate pipe was increased from 200 × 104t to 400 × 104t. Taking the oil temperature of 42 ℃ as the standard, the outflow oil temperature of each station of the pipeline in winter and summer in Dushan station and non-thermal station was calculated separately. By calculating the power of the furnace Based on the viscosity-temperature curve of the crude oil, the kinematic viscosity of the crude oil in the pipe section between the stations was calculated. The pump characteristic was obtained from the characteristic curve of the pump with the parallel connection of the pumps. Pressure, friction loss along the way and get the pump data.
