Title
(EN) WELL COMPLETION SYSTEM
(FR) SYSTEME DE COMPLETION D'UN PUITS DE FORAGE
Abstract
(EN)
A well completion system comprises production tubing (5) extending downhole from wellhead equipment (2) to a plurality of completion systems (7, 8, 9). A well testing facility comprising a test loop (26) with flow metering equipement (27) is included in the wellhead equipment. Each of a plurality of independently adjustable flow control means (57) is operable to stop the flow of fluid from a respective one of the completion assemblies into the production tubing. The downhole completion assemblies (7, 8, 9) are mounted on a common fluid and electrical supply means (4) comprising tubular electrical conductor means (42) and tubing (41, 45, 46) defining fluid paths.
(FR)
Système de complétion d'un puits de forage comprenant une colonne de production (5) s'étendant vers le bas du puits à partir d'un équipement de tête de puits (2) jusqu'à plusieurs systèmes de complétion (7,8,9). L'équipement de tête de puits comprend une installation d'essai comportant une canalisation parallèle d'essai (26) associée à un système débitmètre (27). Chacun des systèmes de commande de l'écoulement (57) réglables de manière indépendante, peut être mis en oeuvre pour arrêter l'écoulement de fluide provenant respectivement d'un des systèmes de complétion, dans la colonne de production. Les systèmes de complétion (7,8,9) situés dans le bas du puits sont montés sur un système commun d'alimentation en fluide et en électricité (4) comprenant un système électroconducteur tubulaire (42) et une ligne de tubes (41,45,46) définissant des voies pour le fluide.
