Abstract

La présente invention concerne un outil de mise en place destiné à mettre en place un outil de forage dans un puits de forage, qui comprend : un mécanisme de mise en place qui sert à appliquer une force de mise en place afin de mettre en place l'outil de forage ; et un indicateur d'orientation qui indique l'orientation de l'outil de mise en place. Un procédé de mise en place d'un outil de forage et de solidarisation d'un ensemble avec l'outil de forage consiste à : mettre en place l'outil de forage dans un puits de forage au moyen d'un outil de mise en place qui est équipé d'un indicateur d'orientation ; puis à solidariser l'ensemble avec l'outil de forage, ce qui permet de fixer l'orientation de l'ensemble par rapport à l'outil de forage. Un procédé permettant d'orienter selon l'azimut un sifflet déviateur dans un puits de forage consiste à : mettre en place une ancre dans le puits de forage, l'ancre étant équipée d'un dispositif d'alignement ; et indiquer une orientation azimutale du dispositif d'alignement par rapport au puits de forage. La mise en place de l'ancre et l'indication de l'orientation azimutale sont effectuées lors d'une incursion unique dans le puits de forage.
