The Research of Demulsifiers's Influence on Oil Emulsion's Rheological Property

Abstract:

Abstract: During the transportation of the oil which is replaced from stratum by return water with demulsifier, the rheology of the water cut oil must have been affected. In order to study the influence rule of emulsion which contains hydrophilic demulsifier, we don this experiment which tests the different demulsifier using HAAKE Viscotester 550. The testing result showed that for crude oil emulsion, the effects of the factors on the rheological index and demulsifier evaluation index into corresponding relation, this provides the rheological field development significance; Demulsifier could move forward the emulsification diversion point, and the viscosity of the emulsion decreased effectively with different moisture contents. Different structure types of demulsifier have the different influence on viscosity. Finally, we conclude the influence rule of emulsion which provides the daterbase for crude oil heating airtight gathering and transportation technology .
