摘　　要：以大庆采油六厂原油为研究对象,考察了不同油水组成乳化油的粘温关系;对低温破乳剂FP330的破乳效果进行了评价,结果表明:40℃时,加入破乳剂的量占乳化油的体积比为80μg.g-1时,脱水效果较好。破乳剂有助于液滴并聚,破乳速率符合一级速率方程。The crude oil of the No. 6 Oil Recovery Factory in Daqing Oil Field was studied. The temperature - viscosit of the emulsifying oil of different oil/water ratios .was investigated. The demulsifiation effec using FP330 at low temperature was studied. The results showed that demulsifier FP330 with the dosage of 80μg · g^-1 showes good efficiency of dewatering at 40℃. The application of demulsifier FP330 could raise the coalescence of liquid droplets. Demulsifiation speed of FP330 was first order kinetics.
