SCREENED MULTI-PAIR SYSTEM AS A SUPPLY LINE TO INDUCTIVE LOOP FOR HEATING IN HEAVY OIL FIELDS Russian patent published in 2018 - IPC E21B36/04 E21B43/24 H01B7/30 

Abstract RU 2651470 C2

FIELD: electricity.

SUBSTANCE: group of inventions concerns system of several electric pairs of wires for symmetrical supply of the consumer. System of several electric pairs of wires for symmetrical supply of a loop of a wire with capacitive compensation for inductive heating and a covering screen tube, while the straight and reverse wires of the pairs of wires are arranged alternately, being finely and uniformly distributed around the perimeter of the circle inside the screen tube covering these few pairs of wires. And straight and reverse wires always have a cross section in the form of a circle sector. In this case, the screen tube has a concentric multi-layer structure. Outer inner layer of the screen tube is made of a diamagnetic or paramagnetic material.

EFFECT: increasing the efficiency of electrical power or electromagnetic heating of the pool of heavy oil or oil sands, minimizing environmental risks and increasing the efficiency of the system due to high electromagnetic shielding.
