Sue Cuo oil pipeline is the HuLunBeir oilfield first long distance pipeline, undertakes the main oil conveying task. In order to reduce the cost of crude oil conveying operation cost, optimization mathematical model of Su-Cuo oil pipeline of is builded with the targets of minimization of production operating consumption. The model belongs to the mixed-discrete variable nonlinear optimization problem. The two-level hierarchical model optimization method is applied to find the solution. On the base of the resualt of optimization, it is known that production operating consumption of winter and summer is 18 percent and 28 percent.
