| 摘 要： | 为了缓解油田设备因腐蚀引起的问题,实验通过有机合成方法,用苯甲酸(油酸)和三乙烯四胺及氯化苄合成得到咪唑啉季铵盐缓蚀剂,经过油酸咪唑啉季铵盐缓蚀剂与苯甲酸咪唑啉季铵盐缓蚀剂的复配后,通过静态失重法进行评价。结果表明这类缓蚀剂的最佳加药浓度为30 mg·L-1,此时两种酸类咪唑啉季铵盐含量比为2∶3时的缓蚀效率可以达到97.4%;主剂(苯甲酸∶油酸=2∶3)与硫脲、乌洛托品、乙酰苯胺按比例10∶5∶2∶1复配缓蚀效率可以达到98.4%,符合油田生产需求。

| Abstract: | In order to alleviate oilfield equipment problems caused by corrosion,experiments by the method of organic synthesis,with benzoic acid（ oleic acid）and triethylene tetramine and benzyl chloride was synthesized imidazoline quaternary ammonium salt corrosion inhibitor,through benzoic acid imidazoline quaternary ammonium salt corrosion inhibitor with oleic acid imidazoline quaternary ammonium salt compound corrosion inhibitor,and evaluated by static weight- loss method. Results show that this kind of the best dosing inhibitor concentration of 30 mg·L - 1 ,the two kinds of acids imidazoline quaternary ammonium salt content when the ratio of 2：3 corrosion inhibition efficiency can reach 97. 4% ;Main agent（benzoic acid：oleic acid = 2 ： 3）and thiourea,methenamine,acetanilide 10 ： 5 ： 2 ： 1 distribution of corrosion inhibition efficiency can reach 98. 4% ,can meet the demand of oil field production. |
