Influence of Physicochemical Methods of Treatment on Structural And Mechanical Properties of High-Viscosity Oils of Udmurtia

The group composition, physicochemical and viscosity-temperature properties of paraffinic high-resinous high-viscosity and high-viscosity oils of Udmurtia deposits with structural-mechanical properties are investigated. It was established that the destruction energy of the supramolecular structure formed during cooling for the oil of the Mishkinsky field is 43.9 kJ/m3 , for the oil of the Kiengop field – 12.6 kJ/m3 . The use of physicochemical methods (heat treatment and dilution of a mixed composition with a hydrocarbon solvent) for regulating the rheological characteristics of oils can significantly reduce the structure of the oil disperse system, which corresponds to a fracture energy of not more than 1 kJ/m3. It was found that the relaxation of the structural and mechanical properties of the oil disperse system after its preliminary heat treatment proceeds slowly.
