This article presents the experimental researches results of composition and properties of oil extracted from bitumen-saturated core and produced extra-viscous oil (borehole samples) of the Ashalchinskoye field and their degree of heterogeneity. The comparative analysis was carried out on the basis of chromatographic, rheological and optical experimental researches in accordance with the specially developed methodologies, the interpretation of the results was carried out using methods of mathematical statistics. The influence of increasing temperature (10-80°C) on the heterogeneity of dynamic viscosity of extra-oil was studied using the rheological method. The chromatographic method was used to research the hydrocarbon composition (alkanes of the C10-C40 series) of core oil and borehole extra-viscous oil. The spectrophotometric experimental researches have made it possible to obtain the dependences of the light absorption coefficient for core oil and borehole extra-viscous oil. Based on the experimental researches performed authors revealed differences in the component composition, rheological and optical properties of core oil and borehole extra-viscous oil, obtained the temperature dependence of heterogeneity composition and properties. The results can be used to improve the technology of extra-viscous oil production in the Ashalchinskoye field.
