FIELD: oil and gas industry.
SUBSTANCE: method includes sampling of deposits from oil equipment, identification of a group composition and type for the deposits, a procedure of the preliminary mixing of empty weighing bottles, preparation of 10% petroleum paraffin solutions in these weighing bottles, wherein different hydrocarbons and their composites are used as solvents, bringing the content of the weighing bottles in the drying closet up to a fixed weight. Surveys are performed using petroleum paraffin of the B2 brand, the melting point of pure paraffin and the paraffin upon treatment by different hydrocarbons is determined additionally by differential scanning calorimetry and the efficiency of solvents for asphalt, resin and paraffin deposits is assessed.
EFFECT: improved accuracy of assessment of the reagents efficiency for the removal of the paraffin deposits.
