ENERGY TRANSFER MECHANISM FOR THE BOREHOLE CONNECTION ASSEMBLY Russian patent published in 2021 - IPC E21B23/12 E21B47/12 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the completion of wellbores in the oil and gas industry and, in particular, to a multi-barrel connection for deployment in the borehole. The multi-barrel connection allows one to install the supply of electricity and communication signals both in the side wellbore and in the main wellbore using a capacitive connection and a volumetric resonator. A single connecting unit preferably contains a channel with a first upper hole, a first lower hole, and a second lower hole. The first lower hole is defined at the distal end of the primary passage extending from the canal junction, and the second lower hole is defined at the distal end of the lateral passage extending from the canal junction. The lower wireless power transmission mechanism in the form of a capacitive sensor is located along at least one of the passages between the distal end of the passage and the connection. The volume resonator is located next to the capacitive sensor to amplify the electric field signal of the capacitive sensor.

EFFECT: improved distribution of signal of the wireless power transmission mechanism.
