Abstract

La présente invention porte sur un outil de fond de trou de système de bouchon de fracturation et sur un procédé de fixation d'un système de bouchon de fracturation dans un puits de forage. Un mandrin s'étend d'une première extrémité à une seconde extrémité. Un ensemble de réglage se trouve sur la première extrémité du mandrin et est mobile le long du mandrin. Un ancrage se trouve au niveau de la seconde extrémité du mandrin et est extensible pour venir en prise avec le puits de forage. Un gaz génère une pression pour déplacer l'ensemble de réglage le long du mandrin pour déployer l'ancrage au niveau de la seconde extrémité du mandrin.
