摘　　要：人工水幕技术，是建造储存石油和天然气的不衬砌石洞地下库的关键。一座总库容为300万m^3、9条20m×30m×（484—717）m的中国首座大型地下水封洞库建成，标志我国“国家战略石油地下储备库”的梦想成真。给出了人工水幕技术原理、具体实施关键技术以及水封效果。理论分析与初步实践结果表明，在年均降水量736mm的花岗片麻岩内建造储存原油洞库，是切实可行的。首座大型地下水封石洞储库的施工建设技术，对我国后续的国家战略油气地下储库规划实施，起到了示范启迪与借鉴作用。Artificial water curtain is the key technology of unlined underground oil and gas storage cavern. China＇ s first large-scale groundwater-sealed cavern with a total capacity of 3 million m3 and 9 chambers of 20m × 20m × （484-717 ）m was built. Hence China＇ s ＂national strategic underground storage of petroleum＂ was materialized. In the present paper, the principle of artificial water curtain, the key technologies of specific implementation, and the water seal effect are presented. Theoretical analysis and actual practice show that it＇ s feasible to build crude oil storage cavern in granitic gneiss with average annual precipitation of 736mm. Technologies of constructing the first large underground oil storage cavern is of guiding importance for subsequent caverns
