Abstract
La présente invention concerne un outil de coupe à pression ultra-haute (UHP) inséré dans un puits de forage pour découper l'enveloppe du puits de forage de l'intérieur de celui-ci. L'outil de coupe comprend un raccord pour tuyau flexible UHP relié à une source de fluide; un tube UHP rotatif avec une extrémité supérieure en communication fluidique avec le raccord de tuyau UHP et une extrémité inférieure à l'opposé de l'extrémité supérieure; un dispositif de rotation en communication fonctionnelle avec le tube UHP pour faire tourner ce dernier lors du fonctionnement de l'outil de coupe; et tête de coupe en communication fluidique avec l'extrémité inférieure du tube UHP. La tête de coupe comprend un coude UHP pour changer le sens d'écoulement du fluide UHP d'une direction essentiellement parallèle au puits de forage à une direction vers la surface intérieure du puits de forage; un orifice d'alimentation d'agent abrasif raccordé à une canalisation d'alimentation pour recevoir l'agent abrasif à mélanger avec le fluide UHP; enfin, un tube de focalisation pour diriger le mélange de fluide UHP et d'abrasif hors de la tête de coupe et vers la surface intérieure du puits de forage à couper.
