(FR) SYSTÈMES ET PROCÉDÉS DE RÉDUCTION DE COUPLE DE RUPTURE
Abstract: front page image
(EN)A well completion system is provided. In one embodiment, a system includes a wellhead hanger (32) such as a casing hanger. The system also includes a running tool (48) with a stopping protrusion (60) that reduces the likelihood of over-torqueing threads coupling the running tool to the wellhead hanger and that reduces the break-out torque for disengaging the running tool and wellhead hanger from each other upon the completion of casing string cementing. Limiting the thread-per-inch count of the hanger and running tools, respectively, to the range of two threads-per-inch to four threads-per-inch also lowers the break-out torque between the hanger and running tool.
(FR)L'invention concerne un système de complétion. Selon un mode de réalisation, un système comprend une suspension de tête de puits (32), telle qu'une suspension de tubage. Le système comprend également un outil de pose (48) doté d'une protubérance d'arrêt (60) qui réduit la probabilité de survenue de surcouple des filets couplant l'outil de pose à la suspension de tête de puits et qui réduit le couple de rupture pour désengager l'outil de pose et la suspension de tête de puits l'un de l'autre lors de l'achèvement de la cimentation de la colonne de tubage. La limitation du nombre de filets par pouce de la suspension et des outils de pose, respectivement, à la plage de deux filets par pouce à quatre filets par pouce abaisse également le couple de rupture entre la suspension et l'outil de pose.
