Key words:extra heavy oil, rheology, viscosity, chemical type, wax,resin-asphaltene substances
It is revealed the variation of the viscosity of samples from a variety of extra-heavy oil wells Ashalchinskoye field at different temperatures and shear stresses. It is shown that the degree of structure and mechanical strength of the oil systems, as well as the variation of these properties with decreasing temperature is largely determined by their chemical composition, reflecting the degree of their natural transformations.
