The Feasibility Analysis on Oil Transportation under Low-throughput Rate

The throughput rate is greatly reduced in Zhang-Luo oil pipeline because the production has been reduced in Zhongyuan oilfield. In order to avoid the forward and back pumping and decrease production cost, the feasibility analysis has been made on the transportation under the low-throughput rate. Based on analyzing on the operational parameters of Zhong-Luo parallel line in 1995, the paper points out that the line can be operated under the low-throughput rate in the condition of keeping a proper wax thickness and reduce the total heat transfer coefficient of the line, The low-throughput transportation test in the line was made from January to August in 1996, and the statistical analysis was made on the operatioal parameters to ascertain the line's optimal operation program. It is pointed out that the transportation process under the low-throughput rate has got obvious economical and/or social benefits.
