摘　　要：为保障国家天然气安全平稳供应,2019年国家能源局启动了川渝天然气千亿立方米级“气大庆”的建设项目,将四川盆地天然气储气调峰和战略应急保供能力建设提升至国家战略安全高度。此外,中国石油在“十四五”期间确立了打造“西南储气中心”的战略目标,积极攻关各项地下储气库(以下简称储气库)建库技术难题,已初步形成“西南储气中心”建设格局。为此,在分析四川盆地建设储气库面临的挑战基础上,系统梳理总结了中国石油近17年在四川盆地的发展规划、建设现状、技术进展等方面的成果,并对打造“中国西南储气能力”提出了具体的攻关方向。研究结果表明:(1)四川盆地天然气资源丰富且拥有与全国天然气管网互连互通的完善管网设施,能够为盆地储气库建设提供坚实基础;(2)提出了复杂盆地气藏的“十指标”选址体系,建立了完善的储气库库址优选技术;(3)形成了储气库建库运行七大特色技术,健全了碳酸盐岩气藏建库主体技术系列;(4)构建了国内首个储气库地质体、井、地面完整性管理评价技术体系,保障了储气库安全稳定运行。结论认为,为支撑国家天然气千亿立方米级“气大庆”建设,提出了“中国西南储气能力”建设的概念,其核心是以中国石油初步建成的企业级“西南储气中心”为基础,走出单一油公司储气库建设模式,建立政府主导协调、跨企业的储气库协同共建共享共营机制,全面推动四川盆地整体储气能力建设,保障国家天然气能源安全。In order to ensure national safe and stable supply of natural gas,the National Energy Administration launched the "Gas Daqing" construction project of 100 billion cubic meters level in the Sichuan-Chongqing area in 2019,which raises the Sichuan Basin's natural gas storage & peak shaving and strategic emergency supply guarantee capabilities to the national strategic safety level.During the "14th Five-Year Plan" period,CNPC has set the strategic goal of building a "Southwest China Gas Storage Center",has been actively tackling various technical difficulties in the construction of underground gas storage(UGS),and has preliminarily formed the construction pattern of "Southwest China Gas Storage Center".After analyzing the challenges to the UGS construction in the Sichuan Basin,this paper systematically summarizes CNPC's achievements in development planning,construction status and technological progress in the Sichuan Basin in the past 17 years,and points out the specific research direction for the construction of "Gas Storage Capacity in Southwest China".And the following research results are obtained.First,the Sichuan Basin is rich in natural gas resources,and there are complete pipeline network facilities interconnected with the national natural gas pipeline network,which can provide a solid foundation for the UGS construction in the Sichuan Basin.Second,a "ten-index" site selection system for complex gas reservoirs in the Sichuan Basin is formed,and complete UGS site selection technologies are established.Third,seven characteristic technologies for UGS construction and operation are formed,and the main technology series for rebuilding UGSs from carbonate gas reservoirs are improved.Fourth,the first domestic integrity management evaluation technology system of UGS geological body,well and surface is established,which ensures the safe and smooth operation of UGSs.In conclusion,to support the construction of the national "Gas Daqing" of 100 billion cubic meters level,this paper puts forward the concept of constructin
