一、前言咪唑啉型缓蚀剂是一类新型的高效缓蚀剂,其应用范围较广。这类缓蚀剂在采油、采气工业中,能抑制油气井内H_2S气体的腐蚀;在炼油工业中能抑制HCl-H_2S—H_2O酸性介质的腐蚀;在清洗锅炉、热交换器、设备管道等方面可作为酸洗缓蚀剂;在油田水、海水中使用,亦有显著的缓蚀效果。咪唑啉型缓蚀剂不仅能在中性条件下使用,而且可在酸性条件下使用。它还具有“一剂多效”的特性,除了具有良好的缓蚀性能外,还具有杀菌、破乳、阻垢等性能。这类缓蚀剂使用剂量少,缓蚀效果显著。目
I. Introduction Imidazoline-type corrosion inhibitor is a new type of high-efficient corrosion inhibitor, its application is broader. Such corrosion inhibitors in the oil and gas production industry, can inhibit gas wells H_2S gas corrosion; in the oil refining industry can inhibit the corrosion of HCl-H_2S-H_2O acid medium; in the cleaning of boilers, heat exchangers, equipment, pipes and so on Can be used as pickling corrosion inhibitor; In oilfield water, sea water, there are significant corrosion inhibition. Imidazoline type corrosion inhibitor can not only be used under neutral conditions, but also under acidic conditions. It also has a “one dose of multi-effect” features, in addition to having a good corrosion inhibition, but also has sterilization, demulsification, scale and other performance. Such a small dose of corrosion inhibitor, corrosion inhibition effect is significant. Head
