摘　　要：从乌鲁木齐到兰州、全长1 838 km的西部原油管道是我国西部石油输送战略通道。该管道建设和运行过程中遇到了一系列严峻的技术挑战,包括管输原油品种多、物性差异大且不确定性强,原油管道与成品油管道长距离同沟敷设带来两管间的热力影响,以及采用顺序输送、冷热油交替输送、含蜡原油常态化间歇输送等几乎所有的原油管道复杂运行方式。通过技术创新,成功地解决了上述技术难题,形成了多品种原油加剂改性顺序输送、长距离管道冷热油交替输送、长距离顺序输送含蜡原油管道间歇输送、同沟敷设管道热力影响数值模拟、含蜡原油管道停输凝管概率评价方法等输油新技术成果。2007年管道投产以来,这些成果的综合应用满足了各种复杂输送任务的要求,确保了管道安全、高效、灵活运行。The West Crude Pipeline, starting from Urumqi to Lanzhou and total length of 1 838 km, is a strategic channel in western China for petroleum transportation. A series of severe technical challenges have been encountered during its construction and operation, such as transporting multiple crudes whose physical properties differ greatly from each other and vary greatly even in a crude from the same source, and the thermal impact between the crude and the products pipelines laid in one ditch, and transporting crudes in almost all complex ways of crude pipeline operation including batch transportation, cold and hot oil batching, and intermittent transportation of waxy crude in normal status. By means of technical innovation, these problems were tackled successfully, and new technologies were developed including batch transportation of multiple waxy crudes combined with pour point depressant treatment, batching of cold and hot crudes through long-distance pipeline, intermittent operation of long-distance waxy crude pipeline, numerical simulation of the thermal impact between parallel collocated pipelines, and the assessment of the restart failure probability of waxy crude pipeline. Since the pipeline was commissioned in 2007, combined applications of these technologies have successfully met a variety of complex transportation requirements and ensure safe, efficient and flexible operation of the West Crude Pipeline.
