An apparatus for selectively orienting a bit (156) at the end of a drill string (135) in a wellbore (133), said apparatus connectable to a motive apparatus (127) for rotating said drill string (135) and said bit (156), said apparatus comprising: a control member apparatus comprising a control member (31) movable to effect a change in orientation of the bit (156) in the wellbore, and a signal apparatus (30) for producing a movement signal indicative of movement of said control member (31), and a controller (60) for communication with said motive apparatus (127) and said control member (31), the controller (60) for translating said movement signal from the control member apparatus into a command signal for the motive apparatus (127), the arrangement being such that, in use, the command signal commands the motive apparatus (127) to rotate the drill string (135) and the bit (156) substantially in correspondence with the movement of said control member (31).
Appareil d'orientation sélective d'un trépan (156) à l'extrémité d'un train (135) de tiges dans un puits de forage (133), ledit appareil étant raccordable à un appareil moteur (127) servant à entraîner en rotation ledit train (135) de tiges et ledit trépan (156), ledit appareil comprenant : un appareil à organe de commande comprenant un organe de commande (31) dont le mouvement permet de modifier l'orientation du trépan (156) dans le puits de forage, et un appareil (30) générateur de signaux servant à produire un signal de mouvement représentant le mouvement dudit organe de commande (31), et un module de commande (60) servant à communiquer avec ledit appareil moteur (127) et ledit organe de commande (31) et à convertir ledit signal de mouvement provenant de l'appareil à organe de commande en un signal d'instruction appliqué à l'appareil moteur (127), de telle sorte qu'en pratique, le signal d'instruction amème l'appareil moteur (127) à entraîner en rotation le train (135) de tiges et le trépan (156) sensiblement en coïncidence avec le mouvement dudit organe de commande (31).
