低输量运行输油管道的理想管路特性曲线

Theoretical Characteristic Curve of Oil Pipeline for Operation of Low Throughput

文章以秦—京线为例,讨论了不同季节、输量、油温和管壁结蜡厚度对低输量运行输油管道的影响,并用数据证实了对该类管道采取必要的工艺措施,用保持适当结蜡厚度的方法,可使管路尽可能地运行在相应的理想管路特性曲线土,并使输油生产的油、电综合能耗费用最低,达到经济运行的目的。

Taking Qin-Jing Pipeline as an example, the paper makes a discussion on the influence of different seasons, throughputs, oil tempretures and wall wax bonding thickness on oil pipeline operation of low throughput. It uses data to prove that if such pipeline adopts necessary processing by way of keeping wax thickness on a reasonable level, so that pipeline could be operated on the theoretical characteristic curve as much close as possible. In such case that the combined energy consumption of oil and electricity for pipeline operation is the minimum and the object of economical operation is obtained.
