Title
(EN) WELLHEAD ASSEMBLY
(FR) ENSEMBLE TÊTE DE PUITS
Abstract
(EN) A wellhead assembly (10) comprising a wellhead (12) having a tubular wellhead body (14, 14') with an outer surface, a wellhead casing (16) which extends from a first end of the wellhead body (14, 14'), the wellhead casing (16) having an outer surface, and a proximal end (16a) and a distal end (16b) relative to the wellhead body (14, 14'), and a tubular outer casing (24) having an inner surface, there being an annular space (30) between the inner surface of the outer casing (24) and the outer surface of the first end of the wellhead body (14, 14') and wellhead casing (16), wherein the system further comprises a solid cement liner which extends from the inner surface of the outer casing (24) into the annular space (30), and a fluid sleeve which extends from the outer surface of one or both of the wellhead casing (16) and first end of the wellhead body (14, 14') into the annular space (30).
(FR) L'invention concerne un ensemble tête de puits (10) comprenant une tête de puits (12) qui présente un corps de tête de puits tubulaire (14, 14') ayant une surface extérieure, un tubage de tête de puits (16) qui s'étend à partir d'une première extrémité du corps de tête de puits (14, 14'), le tubage de tête de puits (16) ayant une surface extérieure, ainsi qu'une extrémité proximale (16a) et une extrémité distale (16b) par rapport au corps de tête de puits (14, 14'), et un tubage extérieur tubulaire (24) ayant une surface intérieure. Un espace annulaire (30) se trouve entre la surface intérieure du tubage extérieur (24), la surface extérieure de la première extrémité du corps de tête de puits (14, 14') et le tubage de tête de puits (16). Le système comprend en outre un revêtement de ciment solide qui s'étend à partir de la surface intérieure du tubage extérieur (24) dans l'espace annulaire (30), ainsi qu'un manchon à fluide qui s'étend dans l'espace annulaire (30) à partir de la surface extérieure du tubage de tête de puits (16), de la première extrémité du corps de tête de puits (14, 14') ou des deux.
