　　The crude oil in Longdong area is produced in the form of emulsion containing associated oil and water which needs to be separated before dispatch to end user.Chemical demulsification is most widely used technology to break the emulsions.A series of experiments on low temperature demulsifies were implemented for studying demulsification performance by Bottle Test method and Turbiscan stability analyzer to study the effect of water content,temperature,and demulsifier concentrations.Rheological method is used to determine the curve of viscosity-temperature.Different commercial demulsifiers were used.Efficient low temperature AR102,AR901,PR929,and PRC06 demulsifiers were selected.PRC06 was chosen to be the best at 40oC,and when the optimal concentration was 200mg/L,dehydration rate was 99.51%,and study was performed to observe dehydration condition of different demulsifiers,the dehydration performance was convincingly high.
