Title (EN) REDUCING WEAR ON WELL HEAD
(FR) RÉDUCTION DE L'USURE SUR UNE TÊTE DE PUITS
Abstract: front page image
(EN)A well head assembly for sub sea wells, comprising a well head housing (1) secured to a well casing by welding along the top portion of the latter in a weld zone (8). The lower part of the well head housing (1) has an area (3) with a reduced thickness at a distance from the weld zone (8), so as to be flexible and to absorb bending force induced on the well head housing (1) during riser operations.
(FR)L'invention concerne un système de tête de puits pour des puits sous-marins, lequel comprend un boîtier de tête de puits (1) fixé à un tubage de puits par soudure le long de la partie supérieure de ce dernier dans une zone de soudure (8). La partie inférieure du boîtier de tête de puits (1) comprend une zone (3) d'épaisseur réduite à distance de la zone de soudure (8), ceci de manière à être flexible et à absorber les forces de courbure induites sur le boîtier de tête de puits (1) lors d'opérations sur la colonne montante.
