Title (EN) FRAC PLUG SETTING TOOL WITH TRIGGERED BALL RELEASE CAPABILITY
(FR) OUTIL DE RÉGLAGE DE BOUCHON DE FRACTURATION AVEC CAPACITÉ DE LIBÉRATION DE BALLE DÉCLENCHÉE
Abstract:
(EN) A downhole tool and process for introducing the downhole tool into a wellbore are provided wherein the downhole tool includes an occlusion-releasing tool. The occlusion-releasing tool contains an occlusion until such time as it is needed in a frac plug to prevent flow in one direction in the wellbore. The occlusion is released from the occlusion-releasing tool by fluid flow through the occlusion-releasing tool. The fluid flow acts directly on the occlusion to provide sufficient pressure to release the occlusion from a mechanical retainer.
(FR) L'invention concerne un outil de fond de puits et un procédé pour introduire l'outil de fond de puits dans un puits de forage, l'outil de fond de puits comprenant un outil de libération d'occlusion. L'outil de libération d'occlusion contient une occlusion jusqu'à ce qu'elle soit requise dans un bouchon de fracturation pour empêcher l'écoulement dans une direction dans le puits de forage. L'occlusion est libérée de l'outil de libération d'occlusion par écoulement de fluide à travers l'outil de libération d'occlusion. L'écoulement de fluide agit directement sur l'occlusion pour fournir une pression suffisante pour libérer l'occlusion d'un dispositif de retenue mécanique.
