庆俄原油顺序输送混油优化研究

对大庆原油和俄罗斯原油顺序输送时，因大庆原油粘度较高，所以顺序输送时对混油量的影响较大，基于顺序输送混油机理，建立了顺序输送混油控制方程，借助ＣＦＤ软件采用有限体积法，对不同流速的顺序输送过程进行了数值计算，分析了在不同流态下大庆原油的粘度越低混油量越小的原因。同时，提出了如下建议：在混油交界面处，往大庆原油中加入适量的降粘剂或掺入适量的柴油降低其粘度，以减少顺序输送过程中大庆原油和俄罗斯原油的混油量。

Daqing and Russia Crude Oil Batch Transportation Optimization

As the Daqing crude oil’s higher viscosity impacts the quantity of mixed oil,during the process of crude oil batch transportation between the Daqing and Russia,the control equation of mixed oil was established based on the sequence mixed oil conveying mechanism.Using the finite volume method computes batch transportation of different flow velocity through CFD software.And the reason that the lower viscosity of the Daqing oil,the lower quantity of mixed oil under different flow patterns was analyzed.And the feasible suggestion was that was adding adequate amount of viscosity breaker chemical or moderate diesel oil into the Daqing crude oil nearby the interface in order to decrease the quality of mixed oil in the process of transportation.
