FIELD: well drilling equipment. SUBSTANCE: device consists of deflecting motor, additional motor - rotating motor and hydraulic distributor. Body of main motor - deflecting motor is rigidly connected with rotating stator of rotating motor. Rotor of rotating motor is connected by means of flexible pipe and spindle shaft with drill string. Novelty in assembly is location of hydraulic distributor below rotating motor and its make in the form of piston-cylinder interconnected by splined joint. Cylinder with nozzle has hole and clutch half-coupling with one tooth engageable with companion half-coupling made on end of sub. Piston is connected with drill string by means of fixed pipe located inside rotor and flexible pipe and spindle shaft. In addition, sub connecting spindle and stator of rotating motor is made with hole. EFFECT: higher efficiency of drilling due to exclusion of breaks in drilling process. 1 dwg
