摘　　要：为了及时把握地下储气库建设技术研究现状,系统地梳理了枯竭油气藏储气库、盐穴储气库、含水层构造储气库的建设及垫底气的设计、提高地下储气库有效储量和生产能力的相关技术、地面系统自动化控制等地下储气库通用技术研究现状及其应用情况。结论认为,我国地下储气库建设技术的研究现状可概括为:国内枯竭气藏建库技术基本成熟;枯竭油藏建库技术尚在摸索之中;盐穴储气库建库技术取得了长足的进步;含水层构造储气库的研究才刚起步。进而提出了我国今后一段时期地下储气库建设的相关建议:①枯竭油气藏仍是我国地下储气库建设的主要类型,应关注相关技术的发展;②盐穴储气库的相关技术需要持续关注,但应当将主要研究力量放在相对薄弱的技术环节上;③我国含水层构造储气库的建设应学习、消化国外相关技术,针对具体的地质条件,加快对注排机理、渗透机理、建库方式、建库周期、井网部署、方案设计和施工技术等的研究;④应高度重视地下储气库建设相关标准、规范的建立;⑤应高度重视地下储气库运行的风险管理。In order to timely learn about the underground gas storage(UGS) construction technologies,this paper overviews the present status and field experiences of the involved technologies in the construction of different types of gas storage such as that based on depleted oil-gas reservoirs,salt caverns,aquifer structures,as well as techniques in the design of cushion gas and in improving the efficient capacity of UGS and production capacity.On this basis,this paper points out that the current UGS technical studies should focus on the following 5 aspects:(1) The depleted gas reservoir is still the main option for the UGS construction projects so the involved techniques will be the focus in the present studies.(2) Techniques about the salt cavern UGS should be continuously concerned but the bottlenecking technical problems should be tackled at first.(3) Due to the complexity of source-reservoir-cap assemblage in middle and small basins in China,the UGS built on aquifer structures will have to face great challenges.(4) High attention should be paid to the formulation of codes and criteria for the UGS construction projects.(5) The risk management system should be highly thought in the UGS construction projects.Moreover,it also summarizes the present status of the technology and techniques involved in Chinese UGS construction projects.Even though such technologies for UGS based on depleted gas reservoirs have basically become mature,those for UGS based on depleted oil reservoirs are still being explored;great progress has been made in the construction of salt cavern gas storage,whereas that based on aquifer structures has just started its initial step.Finally the paper concludes with some recommendations on further UGS construction projects in near future.
