摘　　要：在实验室内采用挂片法和电化学法,评价了FHH-02,956和BUCT三种缓蚀剂对油气井二氧化碳腐蚀的缓蚀效果。实验结果表明,缓蚀剂具有选择性,BUCT缓蚀剂针对江苏油田油气井产出水的缓蚀效果较好,腐蚀速率可以从3.06 mm/a降到0.11 mm/a,缓蚀率达96.5%。The inhibition performances of corrosion inhibitors FHH - 02, 956 and BUCT on CO2 corrosion in oil ＆ gas wells were evaluated by laboratory coupon tests and electric -chemical techniques. The tests demonstrate that the inhihitors have their respective selectivity. BUCT inhibitor performs well against the corrosion of water from oil and gas well in Jiangsu oil field. The corrosion rate can be reduced from 3.06 mm/a to 0.11 mm/a and inhibition rate is 96.5%.
