The influence of temperature and "the cold rod" on precipitates' amount and composition is examined for highlyparaffinic resinous oil of Tomskaja region. Rheological properties of precipitates are defined by the content of low- and high-molecular paraffins. The precipitates allocated at the temperature gradient 70/30°C are characterized with maximum viscosity, increased amount of high-molecular paraffin hydrocarbons C41-C70, resins and asphaltenes.
Key words: oil, carbohydrates, asphalt-resin-paraffin deposits, scale inhibitor, the dynamic viscosity.
