Abstract: In the running of isothermal product oil, when the quantity and oil property are determined, the pipeline friction drag of every station is also determined. By investigating the operation way of Fushun-Yingkou product oil pipeline, the optimization model of it is found, just as resource allocation of the total pressure, The mathematical model can be solved by dynamic method. Take the equipments in the product oil pipeline into account, the transportation process to start up the Anshan middle station to increase the transportation capacity of the pipeline is determined in order to meet the needs of southern product oil market.
