Ultrasonic unit for restoring oil wells

  • Published:
Chemical and Petroleum Engineering Aims and scope

A new generation of unit has been developed for acoustic stimulation of wells. Two design schemes are proposed for ultrasonic units, i.e., with a surface-based source of supply (generator) and with placement of it in a submersible device. A features of the new US generators is the presence of two channels for forming an ultrasonic signal, and this makes it possible to connect two magnetostrictive transducers, each with a power of 4 kVA from both sides of the emitter. US submersible well unit is prepared with a diameter of 42 and 108 mm, whose construction makes it possible to use it in two versions: in the first basic version, it is proposed using one well unit fastened to a pump-compressor pipe. In the second version, it is possible to connect a second well unit fastened to the pump-compressor pipe. The ultrasonic unit created may operate at high pressures and temperatures, and it displays high technical characteristics (power, reliability, etc.).
