FIELD: oil and gas industry.
SUBSTANCE: plant comprises electromagnetic emitters arranged along the longitudinal axis of the well assembly at a certain distance from each other, an interface unit with a submersible electric motor mounted in a separate housing in which there is also an electronic control unit connected to input-output matching unit, and excitation generators provided according to the number of electromagnetic radiators which inputs are connected to the outputs of the electronic control unit, and the outputs are connected to excitation windings of the corresponding electromagnetic emitters, parameter sensors installed in the borehole space and connected to the electronic control unit. Each electromagnetic emitter comprises a cylindrical core of a soft magnetic material with axial or orthogonal winding which turns are arranged axially or perpendicularly to the axis of the borehole assembly. The plant comprises a power supply unit included in the interface unit and associated with the electric motor winding of the electric submersible pump for power supply and supply the plant units for inhibiting formation of sediments. The control unit is connected by a communication channel with monitoring and control equipment located on the surface.
EFFECT: enhanced efficiency of protection of well equipment against corrosion and sediments.
