| Abstract: | Phosphonic imidazoline quaternary ammonium salts was synthesized with long chain fatty acid and polyethylene polyamine as raw materials using phosphate as quaternary amination reagent;then mixed with corrosion inhibitor synergist H and T to form a oilfield water injection corrosion inhibitor SW-638. Its optimal composition：imidazoline quaternary ammonium salt 60% , inhibition synergist H 10% and inhibi- tion synergist T 4%. In Yanchang oil.field sewage treatment application of test station, SW-638 dosage of 50 mg/L,after continuous monitoring 30 d. The result showed that specimen surface is bright and no pit- ting, the average corrosion rate of 0. 032 6 mm/a, meet the 〈 0. 076 mm/a oilfield water injection requirements. |
