摘　　要：针对东辛油田采出污水矿化度高、腐蚀严重的问题,合成了一种母体缓蚀剂,将其与增效剂、粘合剂等按一定比例混合,研制出了缓慢释放型长效缓蚀剂GH-1,简述了其制备过程,探讨了GH-1的缓蚀机理,建立了室内评价方法并对其性能进行了评价。现场应用结果表明,GH-1的缓蚀率超过90%,平均腐蚀速度降至0.076 mm/a以下,最长有效期超过300 d,具有有效期长、加注工艺简单、缓蚀效果好等特点。In view of the serious problem of corrosion caused by highly mineralized waste water in Dongxin Oilfield, a parent corrosion inhibitor was synthesized indoors. And a novel slow released corrosion inhibitor GH-1 was developed by mixing the parent corrosion inhibitor with the expansion agent and adhesion agent. Its synthesis, preparative process, mechanisms of corrosion inhibitor and laboratory tests results were presented briefly, The experimental results show that the novel torrosion inhibitor releases composition slowly, the static corrosion inhibition rate and dynamic corrosion inhibition rate are both greater than 90%. The field tests show GH-1 can control average corrosion rate under 0. 076 mm/a, its valid period is longer than 300 days. It has long valid period and excellent corrosion inhibition. And it is easy to work.
