ABSTRACT:
In the oil-producing industry, an apparatus can be used to increase the yield of oil wells developed by conventional methods during production of high viscosity oils. Use of the apparatus results in an increase in the permeability of a reservoir and a reduction in the viscosity of oil, added to an increase in environmental safety by avoiding use of chemical reagents and steam generators. The apparatus applies a high power ultrasonic field in the well bottom zone that reduces viscosity of oil, also heating the well bottom zone. The apparatus comprises a surface ultrasonic generator and at least one ultrasonic magnetostrictive radiator placed at the end of oil well tubing, using high frequency currents that warm the tubing and maintain the viscosity of oil during transport to the surface.
