METHOD FOR REMOVING PARAFFIN PRECIPITATIONS IN TUBING PIPES OF OIL WELLS Russian patent published in 2005 - IPC

Abstract RU 2256064 C1

FIELD: oil industry.

SUBSTANCE: method includes washing tubing pipes using solvent - condensed light hydrocarbons, produced using centrifugal forces of hydraulic cyclone, with insertion of it through behind-pipe space into said tubing columns and circulation with down-pump operating in towards-self mode. Said solvent contains admixture in form of special surfactant, washing is performed at temperature close to temperature of melting of paraffin with loss of said solvent 5-10 m³ in one well.

EFFECT: higher efficiency, broader functional capabilities.
