Abstract

Abstract:

Interfacial properties between Shengli Gudong model oil and preformed particle gel solution were investigated with interfacial tensiometer, interfacial viscoelastometer and Zeta potential instrument. Meanwhile, the effects of the concentration of preformed particle gel solution on interfacial properties and emulsion stability were researched. The results indicate that the interfacial tension, the interfacial shear viscosity and the absolute value of Zeta potential between deionized water/formation water and model oil increase with addition of preformed particle gel. The stability of water-in-oil and oil-in-water emulsion formed by crude oil and preformed particle gel solution enhances as the concentration of the preformed particle gel solution increases.
