Zusammenfassung:	FIELD: oil production, particularly enhanced recovery methods for obtaining hydrocarbons using heat. ^ SUBSTANCE: device comprises electric heater with multithread cable linked to power source. The cable may be lowered in well to hydrate and paraffin deposit top for deposit melting, which provides deposit advancing through well. Device also has electric heating spiral, copper hydrate and paraffin deposit melting concentrator provided with copper rod arranged inside the heating spiral and device for automatic periodical cable thread switching from single-phase to three-phase power supply scheme with time-delay. ^ EFFECT: increased rate of hydrate and paraffin deposits penetration and elimination of emergency cable jams. ^ 2 cl, 1 dwg
