Abstract
(EN)
A method of creating a well bore comprises providing a bore liner (26) in a section of a well bore (20) extending through a formation (22) and providing the liner with at least one frac sleeve (28). A frac bottom hole assembly (BHA) (50) is mounted on a string (52) of jointed pipe and the BHA is run into the well bore through a blowout preventer (16) (BOP). The BHA is located adjacent the sleeve (28). A seal on the BOP is activated to engage the jointed pipe. The BHA (50) is activated to engage the frac sleeve (28). The BHA is then translated to open a port in the frac sleeve. A surface pump then delivers fracturing fluid through the port (174) into the formation surrounding the liner. After stopping the flow of fluid the BHA is translated to close the port in the frac sleeve.

Cette invention concerne un procédé de création d'un trou de forage, comprenant la fourniture d'une chemise d'alésage (26) dans une section d'un trou de forage (20) s'étendant à travers une formation (22) et la fourniture d'au moins un manchon de fracturation (28) sur la chemise. Un ensemble fond de trou (BHA) de fracturation (50) est monté sur un train (52) de tubes raccordés et le BHA est introduit dans le trou de forage par l'intermédiaire d'un bloc obturateur de puits (16) (BOP). L'ensemble fond de trou est situé de manière adjacente au manchon (28). Un joint d'étanchéité sur le bloc obturateur de puits est activé pour venir en prise avec le tube à raccord. L'ensemble fond de trou (50) est activé pour venir en prise avec le manchon de fracturation (28). L'ensemble fond de trou est ensuite entraîné en translation pour ouvrir un orifice dans le manchon de fracturation. Une pompe de surface distribue ensuite un fluide de fracturation à travers l'orifice (174) dans la formation entourant la chemise. Après l'arrêt de l'écoulement de fluide, l'ensemble fond de trou est entraîné en translation pour fermer l'orifice dans le manchon de fracturation.
