摘　　要：采用静态挂片失重法评价缓蚀剂ASL-1、ASL-2和YGC-03对N80钢在盐水及盐膏层钻井液中的缓蚀性能,分析了温度对缓蚀剂性能的影响。试验结果表明,在盐膏层钻井液中,N80钢的腐蚀速率随着温度的升高而增大,缓蚀剂YGC-03对N80钢有较好的缓蚀效果,可控制N80钢的腐蚀速率在0.04mm/a以下。The corrosion inhibition performance of the corrosion inhibitors ASL-1,ASL-2and YGC-03to N80steel in saltwater and evaporite bed drilling fluid were evaluated by static weight-loss method,and the influence of temperature on the corrosion inhibitor performance was analyzed.The results indicates that the corrosion rate of N80steel increases with the temperature increase in evaporite bed drilling fluid.Corrosion inhibitor YGC-03has good corrosion inhibition effect on N80steel,and the corrosion rate of N80steel can be controlled below 0.076mm/a.
