采用电化学测量、表面表征、扫描振动电极技术、旋转电化学石英晶体微天平和x射线光电子能谱等方法研究了新型抑制剂对X65钢在含乙酸的co2饱和油田地层水中的缓蚀行为。结果表明，在浓度为3 × 10−4mol/L时，各缓蚀剂的缓蚀率均可达95%以上。缓蚀剂膜结构致密均匀，有利于化学吸附，对已腐蚀的钢表面比新制备的钢表面更有效。缓蚀剂的吸附活性中心主要集中在N、S原子和共轭体系。
Inhibition behavior of new designed inhibitors for X65 steel in CO2saturated oilfield formation water containing acetic acid has been investigated by electrochemical measurements, surface characterization, scanning vibrating electrode technique, rotating electrochemical quartz crystal microbalance, and X-ray photoelectron spectroscopy. It is found the inhibition efficiency can exceed 95% for each inhibitor at a concentration of 3 × 10−4mol/L. The inhibitor film exhibits a compact and uniform structure, which is more effective for the corroded rather than freshly prepared steel surface due to the facilitation of chemisorption. The active centers of inhibitor adsorption mainly focus on N, S atoms, and conjugation system.
