Title (EN) WELL CONTROL USING A MODIFIED LINER TIE-BACK
(FR) GESTION DE PUITS À L'AIDE D'UN RACCORD DE COLONNE PERDUE MODIFIÉ
Abstract:
(EN) One example of a wellbore control tool and a method of use is described. A leak is detected in a cased wellbore (102) comprising a multiple telescoping casing sections (104). A fluid flows in an uphole direction through the cased wellbore. A flow of the fluid in the uphole direction results in a first force in the uphole direction. The leak is in a first telescoping casing section (212). An open downhole end (206) of a wellbore tool (106) having a weight at least equal to a second force greater than the first force on an uphole end of a second telescoping casing section that is downhole from a location of the leak in the first telescoping casing section is seated. The open downhole end of the wellbore tool provides metal to metal contact against the uphole end (204) of the second telescoping casing section (208) and restricts fluid flow into the leak.
(FR) L'invention concerne un exemple d'un outil de gestion de puits de forage et un procédé d'utilisation. Une fuite est détectée dans un puits de forage tubé (102) comprenant une pluralité de sections de tubage télescopiques (104). Un fluide s'écoule dans une direction allant vers le haut du trou à travers le puits de forage tubé. Un écoulement du fluide dans la direction allant vers le haut du trou produit une première force dans la direction allant vers le haut du trou. La fuite se situe dans une première section de tubage télescopique (212). Une extrémité de fond de trou ouverte (206) d'un outil de puits de forage (106) présentant un poids au moins égal à une seconde force supérieure à la première force sur une extrémité de haut de trou d'une seconde section de tubage télescopique qui est davantage en fond de trou par rapport à un emplacement de la fuite dans la première section de tubage télescopique est mise en place. L'extrémité ouverte de fond de trou de l'outil de puits de forage assure un contact métal-métal contre l'extrémité de haut de trou (204) de la seconde section de tubage télescopique (208) et limite l'écoulement de fluide dans la fuite.
