Title (EN) PRODUCTION SYSTEMS FOR UNDERWATER WELLS
(FR) SYSTEMES DE PRODUCTION POUR PUITS SOUS-MARINS
Abstract:
(EN) Flowlines (28 and 30) carry oil or gas from a caisson (10), in or partly in a recess in a sea bed (12), to a land station (32) and an umbilical (36) also passes between the caisson and the land station. The lines (28 and 30) and the umbilical serve a number of Christmas tree assemblies (24) in the caisson, these being distributed around a vertical axis of the caisson and supported by a drilling template (22) in the caisson which has been used in the drilling of a corresponding number of wells. A manifold (26) lying on the axis connects all the Christmas trees to the flowlines (28 and 30).
(FR) Des tuyaux adducteurs (28 et 30) transportent du pétrole ou du gaz d'un caisson (10), partiellement ou totalement encastré dans le fond de la mer (12), vers une station terrestre (32), et une conduite (36) relie également le caisson et la station terrestre. Les tuyaux (28 et 30) et la conduite alimentent plusieurs ensembles en arbre de Noël (24) situés dans le caisson; ces ensembles sont placés autour d'un axe vertical du caisson et portés par un gabarit de forage (22) qui a été utilisé pour le forage d'un nombre de puits correspondant. Un collecteur (26) reposant sur l'axe relie tous les arbres de Noël aux tuyaux (28 et 30).
