Factors Evalution of Particle Size Distribution of Heavy Oil Emulsion

Abstract

Used the heavy oil of Du 84 well 53-55 in Liaohe oil field, the impact factors of the heavy oil emulsion size distribution were analyzed. The higher concentration of emulsifier, the smaller size of average particle emulsion and the particle size distribution tends to be more uniform. With the stirring rate increasing the size distribution tends to be uniform first then tend to be disperse, and the time used would be shorter to reach equilibrium with agitation rate being faster.With prolong of the stirring time the particle size distribution of the emulsion trends to be more uniform. After emulsifier 0.3%LZC-C-02 being added in heavy oil it will become O/W emulsion and the external phase is water and the viscosity of the emulsion is small with good flowability.
