Definitions

  • the ultrasonic transducers 23 are high-alloy nickel sheet packets vibrating in the longitudinal direction at a resonance frequency and, with their sound-radiating surfaces 26, face the well wall 16 in such a way that the ultrasonic waves from the shortest possible distance and perpendicular to the inside 29 of the well wall 16 or the openings 17 and then also have a cleaning effect behind the openings 17 in the area of the gravel layer 18.
  • the adjusting device 24 comprises parallel links 30, 30 'and 31, 31', respectively.
  • Each pair of parallel links 30, 30 'or 31, 31' which are arranged in a V-shape with respect to one another, is articulated on the one hand on the supports 27 and with the other ends of the parallel links 31 directed downward by the ultrasonic oscillators 23, 31 'is articulated on a sleeve 32 arranged in the center of the well and, for example, coaxially to the well axis 28.
