FIELD: oil and gas industries.
SUBSTANCE: group of inventions relates to multilateral wellbore systems and to a method for wireless transmission between wellbore components. The multilateral wellbore system has a single connecting assembly containing a channel with the first upper hole, the first lower hole and the second lower hole. The first lower hole is defined at the distal end of the main passage formed by the channel and extending from the channel junction formed along the pipeline. The second lower hole is defined at the distal end of the lateral passage formed by the channel and extending from the channel junction. The multilateral wellbore system also includes an upper power transmission mechanism (PTM) installed along the channel between the first upper hole and the channel junction; the lower wireless power transmission mechanism (WPTM), installed along one of the passages between the distal end of the passage and the upper PTM, and the upper PTM is connected through a wire connection with the lower WPTM. The system also includes a cavity resonator. The cavity resonator has a cavity formed therein. The lower WPTM at least partially is located inside the specified cavity. The cavity resonator provides the focusing of the electromagnetic field in the radial direction.
EFFECT: technical result consists in ensuring the efficiency of the multilateral well system.
