摘　　要：利用极化曲线法和扫描电镜分析对不同浓度水溶性咪唑啉酰胺缓蚀剂在1000mg/L HCl+500mg/L H2S腐蚀介质中对低碳钢(A3)的缓蚀作用进行了研究。结果表明:在HCl-H2S腐蚀介质中,加入浓度为15mg/L时,水溶性咪唑啉酰胺缓蚀剂对低碳钢(A3)具有很好的缓蚀作用。Corrosion inhibition of low carbon stell（A3）in 1000mg/L HCl＋500mg/L H2S corrosion medium by water solutions of inidazoline amide with different coucentrations was studied by polarization curve method and scanning electron microscopy.The results indicate that water-soluble imidazoline amide in a good corrosion inhibitor for low carbon steel（A3）in HCl-H2S corrosion medium atea concentration of 15mg/L.
