Abstract: Taking Qin-Jing Pipeline as an example, tie paper makes a dis-wall wax bonding thickness on oil pipeline operation of low throughput. It uses data to prove that if such pipeline adopts necessary pròcessing by way of keeping w ax thickness on a reasonable level, so that pipeline could be op-erated on the theoretical characteristic curve as much close as possible。In such case that the combined energy consumption of oil and electricity for pi-peline operation is the minimum and the object of economical operation is obtained.
