摘要
近年来,随着天然气利用规模的扩大,储气设施建设的受重视程度日益提高。为了在云南省集约高效地开展储气设施建设,提出了利用煤制气项目和生物天然气项目配合管道气统筹开展储气设施建设的思路。通过集约高效的手段统筹不同气源和储气设施,采用多气源协同发展的方式,可以解决管道天然气在云南省销售数量和发展质量的矛盾,能够实现管道气价值提升、多气源各环节多方共赢的目标。研究结果表明:①云南省煤制气项目2×10^8m^3/a产能和生物天然气项目1×10^8m^3/a产能可以有效保障云南省天然气供应;②通过分析云南省当前用气特点和储气设施建设现状,认定煤制气和生物天然气发展具备可操作性并具有良好的经济效益;③建议以储气设施建设为契机和手段,盘活多种气源,提升储气设施利用效率,形成以管道气为主体、煤制气和生物天然气为补充的供气保障思路,有效落实国家关于加大储气设施建设的政策要求。
With an increase of natural-gas utilization scale in recent years,more and more attentions have been paid to constructing gas-storage facilities.In order to intensively and efficiently construct these facilities in Yunnan Prov ince,we propose one idea on this construction by means of using coal gas,biogenic gas,and pipeline gas as a whole.For pipeline gas,one contradiction between sales volume and development quality can be solved by planning different gas source,and intensive and efficient constructing gas-storage facilities in the mode of multi-gas source joint development.And consequently,two aims to increase its value and to realize win-win of multiple gas source in different links among multiple parties can be achieved.Results show that(1)in Yunnan Province,the productivity of both coal gas projects(2×10^8 m^3/a)and biogenic gas projects(1×10^8 m^3/a)can provide an effective guarantee for the supply of natural gas in province,(2)some analysis on consuming characteristics and construction status of gas-storage facilities indicates that both coal and biogenic gas development is operable with good economic benefit;and(3)it's suggested to take this construction as the opportunity to revitalize multiple gas source and increase utilization efficiency of gas-storage facilities,so as to develop the idea of guaranteeing gas supply with pipeline gas as the soul,and with coal and biogenic gas as the supplement,and to effectively fulfill national policies and requirements on strengthening the construction.
