摘　　要：新疆油田准噶尔腹部地区的原油可通过石西-克拉玛依D273和D377输油管道输送至克拉玛依,如果单独启用其中任一条管道,均需加注添加剂才能完成任务输量并保证管道安全。为此,探索了在不同地温条件下双管并联的输送模式:地温低于管输原油凝点,利用D273管道加注减阻剂运行,停运D377管道;地温高于管输原油凝点,启动D377管道,D273管道停止加注减阻剂,两条管道并联运行。利用该模式输油,每年可节约费用约158×104元,有效地降低了输送成本。The Shixi-Karamay D273 and D377 parallel oil pipelines are used to transport the crude oil(produced from Xinjiang Oilfield in Junggar Region)to Karamay. If either pipeline is started up separately,DRA will be needed to inject pipeline to run the pipeline and ensure its safety operation. Therefore,the dual-pipeline parallel transportation model is explored in the different soil temperature conditions. If soil temperature is below the set point of crude oil,D273 pipeline will be run with DRA,and D377 pipeline is shut down. If soil temperature is above the set point of crude oil,D377 pipeline will be started up,D273 pipeline stops DRA injection,and the parallel pipelines are kept running. Depending on this oil transportation model,the annual transportation cost is saved about 158 ×104 RMB.
