CT2-7是针对胜利油田污水水质特点而研制的注水系统缓蚀剂,采用有机胺盐为基础组分,并配以增效的附加剂而制成的复合缓蚀剂。经室内全面评价和现场工业试验表明,该缓蚀剂不但能较好地抑制均匀腐蚀,而抑制点蚀的效果尤为突出,其腐蚀速率和点蚀速率分别<0.076mm/a 和0.456mm/a。且具有水分散性好、乳化倾向小、能与多种化学药剂配伍使用、无腐蚀、低毒、使用方便等特点。是一种新型的油田注水系统缓蚀剂。
CT2-7 is a corrosion inhibitor of water injection system developed for the sewage water quality of Shengli Oilfield. The compound corrosion inhibitor is made of organic amine salt as the basic component and synergistic additives. The indoor comprehensive evaluation and on-site industrial tests show that the corrosion inhibitor not only inhibits the uniform corrosion but also suppresses the pitting corrosion, the corrosion rate and the pitting corrosion rate are respectively <0.076mm / a and 0.456mm / a . And has good water dispersibility, the tendency of emulsification is small, can be used with a variety of chemical agents, non-corrosive, low toxicity, easy to use and so on. Is a new type of water injection system corrosion inhibitor.
