Title
(EN) AUTONOMOUS INFLOW CONTROL DEVICE HAVING A SURFACE COATING
(FR) DISPOSITIF DE RÉGULATION DE DÉBIT D'ENTRÉE AUTONOME AVEC UN REVÊTEMENT DE SURFACE
Abstract
(EN) An autonomous inflow control system for use downhole comprises a flow ratio control system comprising one or more fluid inlets, and a pathway dependent resistance system comprising a vortex chamber. The one or more fluid inlets provide fluid communication between the flow ratio control system and the pathway dependent resistance system, and at least one of the one or more fluid inlets comprises a super hydrophobic surface.
(FR) Selon l'invention, un système de régulation de débit d'entrée autonome à utiliser en fond de trou comprend un système de régulation de rapport de débit comprenant une ou plusieurs entrées de fluide, et un système de résistance dépendant de la trajectoire comprenant une chambre à tourbillons. La ou les entrées de fluide offrent une communication fluidique entre le système de régulation de rapport de débit et le système de résistance dépendant de la trajectoire, et au moins une desdites entrées de fluide comprend une surface super-hydrophobe.
