FIELD: oil and gas industry.
SUBSTANCE: invention refers to geo-physical surveys of wells and can be implemented at assembly of well apparatus of telemetry system. The unit consists of an internal threaded bushing and of thrust half-rings. The unit also contains a nut-fairing and a profiled bushing with a flange; on the end of the profiled bushing there are made lugs, while response slots are made on the internal threaded bushing. Also one of the lugs of the profiled bushing is thickened in radial direction, while a module, whereon bushings are assembled, has a slot and a circular groove for the thickened lug; an orienting slot is cut on the flange of the profiled bushing; the response lug entering the orienting slot is made on the end of the second module.
EFFECT: upgraded reliability of assembly modules of telemetric system and improvement of its consumer characteristics.
