摘　　要：为了适应原油深度加工的需要,对大庆原油进行深度脱盐研究。在评选破乳剂的基础上,合成出大庆原油高效脱盐破乳剂,对破乳剂的组成与大庆原油脱盐脱水的影响规律,及油水混合强度对原油脱盐效果的影响,油-水界面张力与原油脱盐率的关系进行了研究。To meet the need of the deep processing of crude oil, the deep desalting of Daqing crude oil has been studied. Based on the screening of the demulsifiers, highly efficient desalting demulsifiers for Daqing crude oil were synthesized. In addition, the effect of demulsifier components on desalting and dewatering, the influence of mixing intensity to crude oil desalting were investigated. Data of desalting efficiency and the corresponding interface tension when using different demulsifiers were presented.
