FIELD: mining.
SUBSTANCE: group of inventions relates to devices of deflecting wedge and methods of addressing a male hub in a multilateral well. Device of deflecting wedge consists of upper deflecting wedge, located inside main hole and having a guide spring with inclined surface, lower deflecting wedge, located inside main hole and defining a first channel and a second channel, one of first and second channels is in communication with lower part of main hole and other of first and second channels is in communication with side hole. Upper and lower deflecting wedges are configured for addressing male hub either into side hole, or into lower part of main hole depending on size of tip of male hub.
EFFECT: technical result consists in accurate addressing of male hub in one of shafts of a multilateral well.
