Spatial Optimization of Eastern China's Crude Oil Pipeline Network
基于运费最低的中国原油管道网络空间优化研究

Eastern China's crude oil pipeline network owns the largest number of regional pipelines, and is of the largest network scale and the biggest oil transportation. Here, we analyze 37 oil pipelines and one railway (38 oil flow channels), 20 oil fields with output of over a million tons of crude oil, and 32 refineries which refine over a million tons of crude oil. We construct a supply and demand balance table of oil output and input fields by considering the transportation cost variance of different pipelines with different diameters, to determine the spatial optimization of eastern China's pipeline network. In 2009, the optimal cost of eastern China's pipeline network was a 34.5% decrease compared with the total actual cost, suggesting that oil flow efficiency is overall insufficient, and there is a huge potential for efficiency. The oil flow condition of northeast China's network was relatively better than others, but the condition in north China is inefficient because all pipelines are under insufficient load or no load, and there was a similar condition in Huanghuai region of east China. We assumed no difference in pipeline transport speed because of relatively low transportation for pipelines, compared to rail or road transportation. Transportation distance is the main influential factor, and not time, under the definite transporting cost of different pipelines with different diameters.
