垦西油田污水、原油中含硫较高 ,对油水井及注水设备、注水管网腐蚀严重。我们在室内以环烷酸和二乙烯三胺为原料合成了一种咪唑啉 ,分别经过乙氧基化反应和季铵化反应对其改性 ,得到缓蚀剂FM和FMO ,在模拟垦西油田污水 (H2 S 3 %NaCl 水体系 )中通过腐蚀实验及极化曲线测量对其缓蚀性能进行了评价
Kenxi oilfield sewage, high sulfur crude oil, oil and water wells and water injection equipment, water pipe network corrosion serious. We indoors with naphthenic acid and diethylenetriamine as raw materials to synthesize an imidazoline, respectively, after ethoxylation reaction and quaternization reaction to be modified to get the corrosion inhibitor FM and FMO, in the simulation Kenxi The corrosion performance of oilfield wastewater (H2S 3% NaCl water system) was evaluated by corrosion test and polarization curve measurement
