摘要
In this paper,we used the heavy oil of Du 84,53-55 well in Liaohe oil field,analyzed of the impact factors of the heavy oil emulsion viscosity. When the droplet size of the emulsion is reduced,the viscosity of the heavy oil emulsion increases,and the non-Newtonian obvious. Heavy oil emulsions exhibit Newtonian fluid properties at low shear rate,exhibits shear-thinning properties in the heavy oil emulsion under high shear rate. Heavy oil emulsion viscosity decreases with the increasing concentration of viscosity reducer,when the viscosity reducer concentration of more than 0.25%,heavy oil emulsion viscosity declines slowed.
