摘　　要：介绍了储气库建设的意义和形式及国内外地下储气库的发展现状。就储气库气井用管材,从使用年限、生产过程、载荷变化和腐蚀介质等方面提出了服役的特点和要求,进而针对管材的螺纹接头,结合宝钢特殊扣油管,从密封形式的选择、生产制造的精度保证、必要的复合应力状态下性能评估和使用过程的密封完整性四个方面探讨了储气库气井用特殊螺纹接头的密封完整性这一系统工程。This paper described the significance, forms and development of domestic and foreign underground gas storage constructions. Features of and requirements on the tubings and casings for gas storage wells were proposed from perspectives of the service life, production process, alternate loads and con＇osive situation. With Baosteel＇ s premium connection casings taken as the example, the gas seal integrity of premium thread connections used in gas storage wells was discussed from four perspectives, namely, the selection of the seal form, guarantee of manufacturing precision, evaluation testing under combined loads and application process.
