ENERGY TRANSMISSION MECHANISM FOR A CONNECTION UNIT OF A BOREHOLE Russian patent published in 2021 - IPC E21B41/00 E21B47/12 H02J50/00 

FIELD: machines.

SUBSTANCE: group of inventions relates to multihole borehole systems. The multihole borehole system is comprised of a single connection unit containing a channel with a first top hole, a first bottom hole and a second bottom hole. The first bottom hole is defined on the distal end of the primary branch line coming from the channel connection, the second bottom hole is defined on the distal end of the lateral branch line coming from the channel connection. At least one of the branch lines of the connection unit is deformable. The multihole borehole system is also comprised of a top energy transfer mechanism (ETM) located along the channel between the first top hole and the channel connection; a bottom wireless energy transfer mechanism (WETM) located along one of the branch lines between the distal end of the path and the top ETM, wherein the top ETM is connected by wire with the bottom WETM; and the first tubing string, said string having a distal end with a packing unit and an ETM located on the first tubing string. The first tubing string enters the first hole of the connection channel so that the ETM transferred by the first tubing string is connected to both the ETM and the WETM of the connection channel.

EFFECT: increased efficiency of connection between elements in a multihole borehole.
