摘　　要：LNG运输在LNG产业链中是十分重要的环节,为此,从运输技术经济学角度出发,建立了公路槽车运输LNG的经济模型,计算了LNG运输成本,探讨了槽车几何容积、运输距离、日运输量等因素对LNG运输成本的影响,并以从四川乐山运输LNG到四川西昌为例进行了分析。结果得出如下结论:①利用槽车运输LNG时,运输费用的主要影响因素为槽车储运容积;②运输距离越远、日运输量越大,单位运输成本越低;③每立方米天然气的运输费用随每天运输量的增加呈波形衰减状而逐渐降低,最后将趋近于一个相对稳定的值。LNG transportation is very important in the LNG industrial chain.Based on the economic perspective of transport technology,an economic model for LNG road tanker transportation is established and the LNG transportation costs are discussed.In addition,these factors which affect the LNG transportation costs are studied,including the geometric volume of the road tanker,transportation distance,and daily delivery volume,etc.A case study was performed on the LNG transportation from Leshan to Xichang,two cities in Sichuan province.The result shows that the main factors which influence the transportation cost are the storage and transportation capacity of the road tanker.The farther the transport distance and the larger the daily transport capacity,the lower the unit transportation cost.The transport cost per cubic meter of natural gas is gradually decreased in waveform with the rising of transportation volume per day,finally turns to a relatively stable value.
