Title (EN) DOWNHOLE DEBRIS REMOVAL TOOL AND METHODS OF USING SAME
(FR) OUTIL DE RETRAIT DE DÉBRIS DE FOND ET SES PROCÉDÉS D'UTILISATION
Abstract:
(EN) A downhole tool for removing debris from a wellbore comprises a mandrel and a shroud disposed around a portion of the mandrel. The mandrel includes at least one mandrel port in fluid communication with a mandrel bore. The shroud includes a cavity and a shroud port. Debris laden fluid is pulled into the shroud cavity by flowing fluid through the mandrel bore, out the mandrel port, into the shroud cavity, and through the shroud port. The debris-laden fluid is pulled into the shroud cavity due to a pressure differential created by the flow of the fluid through the mandrel port and out of the shroud port. As the debris laden fluid flows into the shroud cavity, the debris is captured within the tool.
(FR) L'invention concerne un outil de fond de retrait de débris d'un puits de forage comprenant un mandrin et un carénage disposé autour d'une partie du mandrin. Le mandrin comprend au moins un orifice de mandrin en communication fluidique avec un alésage de mandrin. Le carénage comprend une cavité et un orifice de carénage. Un fluide chargé en débris est aspiré dans la cavité de carénage en faisant passer le fluide à travers l'alésage de mandrin, hors de l'orifice de mandrin, dans la cavité de carénage, et à travers l'orifice de carénage. Le fluide chargé en débris est aspiré dans la cavité de carénage du fait d'une différence de pression créée par l'écoulement du fluide à travers l'orifice de mandrin et hors de l'orifice de carénage. À mesure que le fluide chargé en débris s'écoule dans la cavité de carénage, les débris sont capturés à l'intérieur de l'outil.
