FIELD: oil and gas industry.
SUBSTANCE: plant includes at least one production pipeline namely for transportation of bitumens or especially of heavy oil from the formation under the covering rock with reduction of their viscosity. With that, production pipeline is equipped in the minefield with devices for induction heating relative to environment of the production pipeline, which include a high-duty electric generator outside the covering rock and the deposit, direct and return electric wires, as well as inductor lines connected to them. According to the invention, direct and return electric wires of inductor lines pass vertically in the covering rock to the minefield depth and have side distance from each other, which is small in comparison to length of lines and is equal maximum to 10 m. The inductor lines passing horizontally in the formation have different distances from each other in individual sections. With that, in the inductor lines of the formation there formed are sections, the resonant lengths of which are matched so that all the sections have resonance at equal frequency.
EFFECT: improving reliability of induction heating and simplifying the energy input to an underground deposit.
