FIELD: process engineering.
SUBSTANCE: invention relates to automation of pipe running and pulling in oil extraction. Proposed device comprises drilling data base that stores records about pipe elements, controlled-torque wrench with rotation drive, and controller. In screwing off, controller detects records in drilling data base on type of pipe elements to allow wrench torque control or that of rotary device to connect additional pipe section to pipe casing, or to screw off joint between pipe elements in compliance with parametres of given pipe elements joint. Various components of drilling unit incorporate transducers, magnitudes transmitted by said transducers being controlled. Simultaneously with screwing off/on jobs, timers are initiated. When magnitudes red by transducers fall beyond preset range, or when performance of aforesaid jobs last too long to completion, emergent situations originate.
EFFECT: acceleration of jobs at drilling site.
