Title
(EN) HYDRAULIC LINE CONTROLLED DEVICE WITH DENSITY BARRIER
(FR) DISPOSITIF COMMANDÉ PAR CONDUITE HYDRAULIQUE AVEC BARRIÈRE DE DENSITÉ
Abstract
(EN)
The disclosure provides a downhole completion device for use in a wellbore and a subterranean production well. In one embodiment, the downhole completion device includes: (1) a hydraulic line controlled device, the hydraulic line controlled device having a control line port and one or more fluid leakage paths, and (2) a density barrier having first and second ends, wherein the first end is coupled to the control line port and the second end is configured to couple to a control line extending from a surface installation, the density barrier having an axial loop relative to the hydraulic line controlled device and positioned below the fluid leakage path, thereby preventing migration of leakage fluid from the one or more fluid leakage paths to the surface installation.
(FR)
L'invention concerne un dispositif de conditionnement de trou vers le bas destiné à être utilisé dans un puits de forage et un puits de production souterrain. Dans un mode de réalisation, le dispositif de conditionnement de trou vers le bas comprend : (1) un dispositif commandé par conduite hydraulique, lequel dispositif comporte un orifice de conduite de commande et un ou plusieurs trajets de fuite de fluide, et (2) une barrière de densité ayant des première et deuxième extrémités, la première extrémité étant couplée à l'orifice de conduite de commande et la deuxième extrémité étant conçue pour s'accoupler à une conduite de commande qui s'étend à partir d'une installation de surface, la barrière de densité ayant une boucle axiale par rapport au dispositif commandé par conduite hydraulique et positionnée au-dessous du trajet de fuite de fluide, empêchant ainsi la migration de fluide de fuite depuis le ou les trajets de fuite de fluide vers l'installation de surface.
