摘要
为了实现天然气储气设施集约高效建设,避免可能出现的利用率低、重复建设等问题。在分析川渝地区天然气储备能力现状的基础上,通过定量分析,总结出当前川渝地区在天然气储备能力方面存在的3个问题:LNG工厂和储气罐建设可能面临重复建设;储气设施相对独立,互联互通程度不足造成资源浪费;现有市场机制未健全,储气设施盈利的商业模式亟待建立等。再通过多路径措施开展储气设施建设,提出川渝区域储气能力提升策略及实施路径,以期达到保障天然气产运储销安全平稳运行的目的。研究结果表明:(1)坚持集约高效的原则,通过整合地下储气库、LNG加工厂及配套储罐、高压球罐、枯竭气井、生物天然气项目土地储备等现有资源提升储备能力;(2)确立三级调峰体系,通过市场化手段提升储气设施盈利水平,有助于盘活储气设施存量,提高设施利用效率;(3)拓宽储气调峰盈利渠道,探索新的商业模式,进而达到多方共赢的效果。结论认为:随着市场不断完善,储气设施的经营、使用主体将不断增多,价格管制的放开将使天然气储采行为更加市场化,储气调峰建设的政策环境也将不断完善,坚持有机整合的集约高效储气设施建设思路,将有效推动储气市场的健康有序发展。
In order to realize the intensive and efficient construction of gas-storage facilities and avoid both low utilization ratio and duplicated construction which may appear,three problems about the storage capacity of natural gas in Sichuan-Chongqing area were summed up by means of quantitative analysis,containing that the construction of LNG plants and gas-storage tanks may face duplicated construction;most storage facilities are relatively independent without sufficient interconnection,resulting in resource waste;and due to incomplete market mechanism,it’s in essential to establish a profit business model for these gas-storage facilities.In addition,multiple measures were made in facility construction,and several strategies and implementation paths to improve this capacity were put forward so as to guarantee a safe and smooth implementation on production,transportation,storage,and distribution.Results show(1)to stick to the principle of intensive and high efficiency and integrate existing underground gas storages,LNG processing plants,and support storage tanks,high-pressure spherical tanks,depleted gas wells,biogas project land reserves,and other resources to improve the storage capacity;(2)to establish a three-level peakshaving system and make use of market means to improve facility profitability,which is conducive to revitalizing the stock of storage facilities and improve facility utilization ratio;and(3)to broaden profit channels of gas storage and peak shaving and explore a new business model so as to achieve the win-win effect.In conclusion,with continuous improvement of market,most business and users of storage facilities will increase continuously,the deregulation of price control will make natural-gas storage and production more market oriented,and sticking to the idea of constructing storage facilities intensively and efficiently by integrating gas storages,depleted gas wells,LNG storage tanks,high-pressure spherical tanks,and biogas land resources will effectively make healthy and orderly progress on g
