Title
(EN) ATTACHMENTS FOR MITIGATING SET CEMENT DOWNHOLE
(FR) ACCESSOIRES POUR RÉDUIRE LE CIMENT DURCI EN FOND DE PUITS
Abstract
(EN)
A well tool attachment includes a tubular body with a bore therethrough extending along a longitudinal axis, wherein the tubular body is configured to seat in a shoe track of a well casing. A plurality of partitions are suspended from the tubular body, dividing the bore of the tubular body into a plurality of segments extending axially through the tubular body. The partitions are configured to break up cement slurry entering the bore of the tubular body into a plurality of cement segments to facilitate drilling after downhole cement sets.
(FR)
Un accessoire d'outil de puits comprend un corps tubulaire pourvu d'un alésage à travers celui-ci s'étendant selon un axe longitudinal, le corps tubulaire étant configuré pour se loger dans une piste de sabot d'un tubage de puits. Une pluralité de séparations sont suspendues au corps tubulaire, divisant l'alésage du corps tubulaire en une pluralité de segments s'étendant axialement à travers le corps tubulaire. Les séparations sont configurées pour fragmenter le laitier de ciment entrant dans l'alésage du corps tubulaire en une pluralité de segments de ciment afin de faciliter le forage après le durcissement du ciment en fond de puits.
