摘　　要：“十四五”期间,国内地下储气库巨大的调峰缺口与资源劣质化形成鲜明对比,储气库建设面临库址资源缺乏、技术难度升级等技术挑战。通过系统调研分析全球储气库类型及特征,提出了国内储气库库址变化新趋势;从建库新模式、理论技术、配套政策等方面探索了储气库建设发展对策,并针对国内天然气资源与市场分离、多调峰方式并存、储气库类型地域差异等特点,构建了储气库建设总体布局与数字化发展方向。研究得出,国内储气库库址呈现多样化、大型化、复杂化和数字化4大新趋势;通过采用大面积低渗透岩性气藏“三区带”和油藏气驱采油与储气库协同建库的新模式,能够激活一批库址资源,极大提升调峰能力;攻关储气地质体动态密封性评价、高速交互注采渗流机理与库容设计、复杂盐层造腔新工艺及提高空间动用等新技术,能大幅提升运行效率、降低安全风险。研究结果为充分挖掘库址资源、指导复杂储气库高效设计提供了科学支撑。During the 14th Five-Year Plan period,the huge peak shaving gap and resource degradation of underground gas storage(UGS)in China have formed a sharp contrast.UGS construction faces challenges,such as a lack of storage site resources and upgrading of technical difficulties.Therefore,through systematical research and analysis of the types and characteristics of global UGS,new change trends in Chinese UGS sites were proposed,and development strategies for UGS construction from the perspectives of new modes,theoretical technologies,and supporting policies were explored.In response to the characteristics of separation between natural gas resources and markets in China,the coexistence of multiple peak shaving methods,and regional differences in UGS types,an overall layout and digital development direction for UGS construction were proposed.Chinese UGS sites present four new trends,namely diversification,large scale,complexity,and digitalization.The new mode of“three zones”in largescale low-permeability lithological gas reservoirs and collaborative construction of oil reservoir gas drive and UGS can activate a batch of site resources and greatly improve peak shaving capacity.New technologies such as dynamic sealing evaluation of gas storage geological bodies,seepage mechanism and storage design of high-speed interactive injection and production,and new technology for complex salt cavity building and space utilization improvements,can significantly improve operational efficiency and reduce safety risks.The research results provide scientific support for fully excavating site resources and guiding the efficient design of complex UGS.
