| 摘 要： | 针对高矿化度油田污水腐蚀严重的特点，以二乙烯三胺和羧酸为原料，合成了咪唑啉，并进行水溶性改性，合成了咪唑啉衍生物缓蚀剂HS—ZH。以HS—ZH为主体缓蚀剂与有杀菌、除氧等效果的缓蚀增效荆进行复配。用静态挂片失重法考察缓蚀剂的缓蚀性能，采用扫描电镜分析了腐蚀前后试片形貌，对缓蚀剂的作用机理进行了探讨。结果表明，HS—ZH的缓蚀率和稳定性均高于油田常用缓蚀剂HS—XF和HS—TD；复配缓蚀剂加量为10—20mg／L时，缓蚀效果最佳。

| Abstract: | For inhibiting serious corrosion caused by high mineralized wastewater, a imidazoline was synthesized with diethylenetriamine and earboxylie acid, then the corrosion inhibitor HS - ZH was prepared by water- soluble modification,and the water-soluble imidazoline derivative KS- ZH with some synergic agents were compounded. The efficiency of the inhibitors were studied by weight - loss experiment and the morphologies of the test films were observed by scanning electron microscope. The action mechanism of the corrosion inhibitor was discussed. |
