• Apparent viscosity
• Heavy crude oil
• Relative viscosity
• Water-in-oil emulsion

Two series of water-in-oil emulsions with different droplet size distributions were prepared by using Bohai SZ36-1 oilfield heavy crude oil and mineral water. The effects of temperature, water volume fraction, shear rate and droplet average diameter on emulsion viscosity were studied. The results showed that temperature had a great impact on apparent viscosity of emulsion, but seemingly little impact on relative viscosity. Water volume fraction, shear rate and droplet average diameter were also important factors affecting viscosity. At a low water volume fraction, shear rate and droplet average diameter';s effect could be ignored, however, when water volume fraction increased, their effects will be greatly enhanced and W/O emulsion showed strong shearing-thin behavior. Some published viscosity prediction models were evaluated by using data from the experiment, and the Brinkman (1952) model was found to be the best.
