摘　　要：建造了2口试验储气井,对储气井实施了抗拔力测试。得出规格Ф244.48 mm×11.05 mm×71 m试验储气井的抗拔极限承载力大于2932.5 kN,规格Ф177.8 mm×10.36 mm×23 m的试验储气井的抗拔极限承载力为1299.22 kN。当各井段地层信息完整,且经过有效固井,储气井极限抗拔力可采用文中式(2)进行计算,计算结果偏于安全。Two underground gas storage wells （GSWs） for experiment is constructed and the uplift test is carried out. The anti - pull force of the GSW with size of 0244.48 mm× 11.05 mm × 71 m is greater than 2932.5 kN, and the anti - pull force of the GSW with size of 177.8 mm × 10.36 mm ×23 m is 1299.22 kN. For the GSW with effective cementing and complete geology information, the anti - pull force can be calculated by equation （2）, and the calculation result is conservative.
