Abstract

Un procédé et un dispositif de forage dirigé utilisent un outil de forage tournant formé d'un corps tubulaire droit relié à un train de tiges, d'un moteur monté dans ce corps et d'un arbre de prise de force relié au rotor du moteur, monté à rotation dans le corps autour d'un axe de rotation s'écartant de l'axe longitudinal du corps et sortant du corps à l'extrémité inférieure de celui-ci, un outil de forage tournant étant monté sur l'extrémité antérieure du corps dans le prolongement de l'arbre de prise de force.A method and a directional drilling device use a rotary drilling tool formed by a straight tubular body connected to a drill string, a motor mounted in this body and a PTO shaft connected to the rotor of the motor. , rotatably mounted in the body about an axis of rotation deviating from the longitudinal axis of the body and leaving the body at the lower end thereof, a rotary drilling tool being mounted on the front end of the body in the extension of the PTO shaft.
