天然气管道设计输气规模研究

The Research on Natural Gas Transmission Pipeline Design Throughput

天然气管道设计输气规模的确定既要考虑气田资源情况、生产能力,又要考虑天然气利用市场的需求、用户对天然气价格的承受能力、所替代能源的经济性以及国家相关政策的影响等。根据国内外长距离输气管道的建设经验,提出了天然气管道设计输气规模预测研究的内容和方法。依据需求定理,针对不同的天然气管输价格确定不同的管道设计输量,进一步考虑了不同用户用气不均衡性对管道设计输量的影响。

The determination of design throughput for the natural gas transmission pipeline needs to consider the following factors:the resources and the operations of the natural gas fields,the market demand,the users' consumption capability for the natural gas price,the economical properties of the substitution for the gas sources,the influence of the correlative nation policies and so on.On the basis of the construction experiences of long distance gas transmission pipeline at home and abroad,this paper brings forward the research content and methods of the design throughput for the natural gas transmission pipeline.According to the 'demand theory' of the economics theory,the design throughput of different pipelines can be determined in allusion to the different prices of gas pipeline transmission.Furthermore,the influences of the different customers' unbalanced demands on the pipeline design throughput are taken into account.
