应用失重法、动电位扫描和ＥＩＳ等方法， 研究了Ａ３ 碳钢在三元复合驱油剂主要成分水解聚丙烯酰胺（ＨＰＡＭ） 和石油磺酸盐（ＰＳ） 水溶液中的腐蚀形态。结果表明， ＨＰＡＭ 对Ａ３钢具有缓蚀作用， 浓度增加， 缓蚀率上升；ＰＳ对Ａ３ 钢也有缓蚀作用， 但浓度过高时因形成胶束而从碳钢表面脱附， 使缓蚀率下降
The corrosion morphology of A3 carbon steel in aqueous solution of polyacrylamide (HPAM) and petroleum sulfonate (PS), the main component of ASP flooding agent, was studied by weight loss method, potentiodynamic scanning and EIS. The results showed that HPAM had a corrosion inhibition effect on A3 steel, the concentration increased, and the corrosion inhibition rate increased. PS also had a corrosion inhibition effect on A3 steel. However, when the concentration was too high, the desorption from the surface of carbon steel resulted from the formation of micelles, decline
