摘　　要：世界油气藏型地下储气库的调峰工作气量占已经投运地下储气库总工作气量的83%，目前中国天然气调峰应急储备类型也以油气藏型地下储气库的应用最为广泛。为此，分析了全球天然气调峰储备现状及中国天然气调峰应急储备的需求，将国外天然气利用发达国家地下储气库的建设历程划分为3个阶段：发展初期、快速发展期和平稳发展期。论述了油气藏型地下储气库在中国天然气供需产业链中的重要作用：油气藏型地下储气库具有油气藏开发历史情况清楚、建库地质资料丰富、投资经济、建设周期短、投产快等优点，建设周期一般只需3-5年，在有条件的天然气消费区域附近首选油气藏改建地下储气库，可实现快速应急调峰的目标。进而阐述了建设油气藏型地下储气库的核心关键技术：①库容恢复与有效工作气量的优化技术；②储气库运行调峰应急能力优化技术；③储气库交变载荷运行状况下的井身结构优化技术。The peak shaving gas contributed by underground gas storage （UGS） of the reservoir type accounts for 83% of the total working gas provided by the UGS put into operation all over the world. Recently, this type of UGS is the most popular reserves for peak-shaving and emergency use in China. In view of this, this paper first analyzed the status quo of the global peaking reserves and the demand for peaking and emergency reserves in China. The process of UGS in those developed countries has experienced the infan- cy and growth periods and come to the present stable stage of development. Then, it discussed the important role this reservoir type UGS plays in the natural gas supply-demand chain in China because of its unique advantages like available abundant information about geological conditions and development history of the chosen hydrocarbon reservoirs, a short construction period needed, fast corn missioning, and cost effectiveness. In common, a reservoir type UGS only needs 3 - 5 years to be put into operation, so it is the fastest way to achieve the peak-shaving and emergency use especially in those areas in urgent and high needs for natural gas. Moreo-ver, the core technologies for this type of UGS were also discussed： optimization of the UGS capacity to restore and effective work ing gas, optimization of peak shaving and emergency capacity, and optimization of the wellbore configuration in the case of an alter-nating load.
