庆铁线站场改造过渡期优化运行研究

Optimal Operation of Transition Period of Station Reconstruction Linyuan-Tieling Oil Pipeline

为了配合俄罗斯油增输,东北管网需要将庆铁(林源-铁岭)三、四线所输介质进行对调并对相关站场进行改造。在站场改造期间,庆铁三线的输送能力有所下降,管道调节空间减小。通过对管线的水力系统进行重新梳理,计算出过渡期各月最大输量,同时对减阻剂注入点的选取及注入量进行了优化。对照输量要求合理安排运行方式,与原运行方案相比,减少燃料油消耗8200 t,减阻剂使用量减少366桶,整个过渡期共降低运行费用4063万元,取得了较好的经济效益。

In order to cooperate with the increasing of Russian oil, the Northeastern oil pipeline networks will need to exchange the third line with the fourth line of Linyuan-Tieling oil pipeline and reconstruct relevant stations. During the period of reconstruction, pipeline transmission capacity of the third line has declined, and the pipe regulating space has decreased. Through carding the hydraulic system of pipeline, we calculate the maximum throughput of each month during transition period and optimize the injection point and volume of drag-reducing agent. Operation mode is made reasonably in view of the demand of transmission volume. Compared with original operationplan, it not only reduced 8200 tons of fuel oil and 366 barrels of drag-reducing agent, but also greatly cut the cost of oil transportation.
