A method and apparatus for making and breaking tubular connections at the surface of a well by utilizing a pipe joining system. The pipe joining system includes a movable support frame for supporting and integrating on a rig floor the tools associated with making and breaking the connection between two tubulars. Tools incorporated in the pipe joining system include combinations of a wrenching assembly for gripping the tubulars and applying torque to the connection, a spinner for spinning the joints of the tubulars into connection, a positioning tool for vertically and/or horizontally aligning the tubulars in the system, a cleaning and doping device for cleaning and doping the threads of the tubulars, a stabbing guide for properly aligning the tubulars before joining, a mud bucket for handling mud spillage during the breaking of the tubulars, and a control system that remotely operates the entire automated system.

L'invention concerne un procédé et un appareil permettant d'accoupler et de désaccoupler des tuyaux à la surface d'un puits, au moyen d'un système de raccordement de tuyaux. Ce système de raccordement de tuyaux comprend un cadre-support mobile servant à supporter les outils associés aux opérations d'accouplement et de désaccouplement réalisées entre deux tuyaux, ainsi qu'à les intégrer dans un plancher de forage. Parmi les outils que comprend ce système de raccordement de tuyaux figurent, de manière combinée : un dispositif de torsion pour saisir les tuyaux et appliquer une force de torsion à des fins d'accouplements ; un outil de positionnement pour aligner verticalement et/ou horizontalement les tuyaux dans le système ; un dispositif de nettoyage et d'enduisage pour nettoyer et enduire les filets des tuyaux ; un dispositif de guidage pour aligner correctement les tuyaux, avant l'opération de raccordement ; un seau à boue pour gérer un déversement accidentel de boue survenant lors du désaccouplement des tuyaux ; ainsi qu'un système de commande pour télécommander l'ensemble de ce système automatisé.
