Beschreibung
Zusammenfassung:	FIELD: organic chemistry, oil. ^ SUBSTANCE: invention refers to methods of high-viscosity oil treatment in fields before transportation through pipelines, specifically to methods of oil viscosity reduction. Methods of oil viscosity reduction includes cyclic delivery of liquid oil to hydrodynamic treatment zone, where oil is pressured characterized by constant axial shift component and variable cross shift component, post-treatment oil temperature measurement. To provide irreversible viscosity reduction pressure treatment of oil is performed with heat removal to stabilize oil temperature within temperature range, but not lower than temperature rise of which causes insignificant oil viscosity reduction and not higher than oil boiling point. Oil viscosity is measured after pressure treatment. Pressure treatment is finished as oil viscosity stabilizes. Technical result is provision of irreversible oil viscosity reduction. ^ EFFECT: provision of irreversible oil viscosity reduction. ^ 1 dwg
