FIELD: instrument engineering.
SUBSTANCE: group of inventions refers to the node of the wedge-deflector, the downhole system and the method of supporting the torque in the node of the wedge-deflector. Node of the wedge-deflector includes a wedge-deflector having an inclined surface and a longitudinal trough, formed in an inclined surface; guiding router, connected to the wedge-deflector by means of a shear screw and having a groove, formed in it; and a lock with a predetermined torque, configured to move between the extended position and the retracted position. In the extended position, the lock with a specified torque is partially located inside both the groove and the longitudinal chute. With the retracted position, the lock with the specified torque is retracted into the groove. In the extended position, a lock with a specified torque prevents the guide router from rotating with respect to the wedge-deflector.
EFFECT: technical result is prevented premature disconnection of the guide router from the wedge-deflector.
