CA 2308464

A running tool (20, 120, 220) which is intended to be lowered down a tubular member via a wireline (8, 108) extending from the surface to a connection to the upper end of the tool by which the tool is suspended, said tool being capable of advancing itself along the wall of the tubular member when required (e.g. when the tubular member is inclined to the vertical as a "lateral"), by repeated application and release of tension force in the wireline.

L'invention concerne un outil (20, 120, 220) qui est prévu pour s'abaisser dans un organe tubulaire, par un câble électrique (8, 108) s'étendant à partir de la surface jusqu'à un raccordement à l'extrémité supérieure de l'outil par laquelle celui-ci est suspendu. Cet outil peut s'avancer le long de la paroi de l'organe tubulaire lorsque cela est nécessaire (par exemple, lorsque l'organe tubulaire est incliné par rapport à la verticale, en étant "latéral"), par l'application et le relâchement répétés d'une force de tension dans le câble électrique.
