CA 2409062

The present invention provides a system and method for setting an anchor (18) and/or whipstock (20) attached to a downhole motor (28) having a cutting tool (22) attached to a tubular member, such as coiled tubing (16). In one aspect, the motor allows flow therethrough sufficient to actuate an upstream MWD or other position measuring tool (32), and an orienter (34) if so equipped, and retain the orientation of the motor with the attached whipstock. An increased flow rate or pressure actuates the motor once the whipstock is set and rotation of the cutting tool or other equipment can begin.

La présente invention concerne un système et un procédé permettant de mettre en place un élément d'ancrage (18) et/ou un élément de déviation (20) fixé à un moteur de fond (28) présentant un outil de coupe (22) fixé à un élément tubulaire tel qu'un tubage spiralé (16). Dans un aspect de l'invention, le moteur permet d'obtenir un flux suffisant pour actionner un système MWD (measuring-while-drilling / mesure de fond pendant le forage) ou tout autre outil de mesure de position (32), et, le cas échéant, un élément d'orientation (34), et permet de maintenir l'orientation du moteur auquel est fixé l'élément de déviation. Un débit ou une pression élevé(e) entraîne le moteur lorsque l'élément de déviation est mis en place et l'outil de coupe ou autre instrument peut alors commencer à tourner.
