FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil and gas industry and can be implemented for raising yield of low producing wells and for development of oil deposits with high viscous oil. There is generated ultrasonic radiation; further it is directed from the above surface part of the well via the casing pipes as via the wave guide to a receiving part of the well. The casing pipes are coated with several layers of sound insulating materials with different sound speed in them, or there are used the casing pipes with lengthwise or screw channels located nearer to external surface and filled with air or another substance with a speed of propagation of sound not less, than 3000 m/sec, or there are used the casing pipes coated with sound insulating layer on the base of honeycomb or cell structures filled with air or other material. The device consists of the above said casing pipes, of a generator of electric oscillations for feeding electro-mechanical converter of electric oscillations connected to the casing pipe.
EFFECT: protection of cement stone behind casing pipes and improvement of transmitting properties of wave guide from casing pipes.
