Temperature viscosity features of extra heavy oil of the Ashalchinskoye field

Authors: G.P. Kayukova, G.V. Romanov (A.E. Arbuzov Institute of Organic and Physical Chemistry, Kazan Scientific Centre of RAS, RF, Kazan) , I.M. Abdrafikova, S.M. Petrov (Kazan National Research Technological University, RF, Kazan)

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.
