摘　　要：以脂肪酸、多乙烯多胺、1,4-双(氯甲基)苯等为原料合成了一种用于油田注水的双咪唑啉缓蚀剂。用静态失重法测定了影响该产品缓蚀性能的各种因素。试验结果表明,以某油田注水为介质,当双咪唑啉缓蚀剂投加质量浓度为30 mg/L时,平均腐蚀率可控制在0.075 mm/a以下。Bis-imidazoline has been synthesized with fatty acid, muhiethylenemultiamine and 1,4-bis （chloromethyl） benzene etc., which can be used for oilfield water injection as corrosion inhibitor. Influential factors of the corrosion inhibition on different conditions have been evaluated by taking the oilfield water injection as medium, the average static weight-loss method. The test result indicates that corrosion rate can be controlled at less than 0.075 mm/a, when the dosage of the corrosion inhibitor is 30 mg/L.
