摘　　要：采用室内静态失重法研究了隐形酸完井液中N80钢、A3钢的腐蚀行为,并对抑制这两种钢腐蚀的缓蚀剂进行了优选。结果表明,增加隐形酸螯合剂(HTA)的浓度,钢片的腐蚀速率加快;在溶液中加入NaCl,钢片腐蚀更加严重。研制的缓蚀剂JHA-03可有效抑制N80钢、A3钢在隐形酸完井液中的腐蚀。The corrosion behavior of N80 steel and A3 steel were studied in acidic completion fluid by static weight-loss method, and the corrosion inhibitors for both steels were optimized. The results indicated that the corrosion rate of steel increased with the concentration of recessive acid （HTA）, and corrosion got worse by adding NaCl in solution. Corrosion of the two types of steels could be effectively inhibited by JHA-03.
