    Abstract：Corrosion always is the most serious problem for safety production in oil and gas industry. In order to increase oil and gas production efficiency， analyzed are corrosion characteristics of produced water from some oilfield， oleic acid and diethylenetriamine are used as raw materials for synthesizing imidazoline intermediates， acetic acid and benzyl chloride are used for modifying such imidazoline intermediates， infrared spectrum is used for characterizing their structures and static corrosion weight-loss method and electrochemical method are used for their inhibitor performance study. Infrared spectrum shows that the synthetic products are target products， static weight-loss method shows that corrosion inhibition efficiency of the products modified by using benzyl chloride is better than those modified by using acetic acid and electrochemistry curve shows that the end production and intermediates are anodic inhibitor.
