Title (EN) DEGRADABLE METAL BARRIER FOR DOWNHOLE SCREENS
(FR) BARRIÈRE MÉTALLIQUE DÉGRADABLE POUR TAMIS DE FOND DE TROU
Abstract:
(EN) A method and system for temporarily preventing fluid flow through a screen assembly installed in a wellbore can include a screen assembly interconnected in a tubing string. Components of the screen assembly can include a base pipe, one or more filter layers, an optional drainage layer(s), with flow paths through each of the components. A degradable metal barrier can be applied to at least one of the components, which thereby temporarily prevents fluid flow through the flow paths, and temporarily provides pressure isolation radially between an interior and an exterior of the screen assembly. Degradation of the metal barrier can allow fluid and pressure communication radially between the interior and the exterior of the screen assembly.
(FR) L'invention concerne un procédé et un système permettant d'empêcher temporairement un écoulement de fluide à travers un ensemble tamis installé dans un puits de forage pouvant comprendre un ensemble tamis interconnecté dans une colonne de production. Des éléments de l'ensemble tamis peuvent comprendre un tuyau de base, une ou plusieurs couches de filtre, une ou plusieurs couches de drainage optionnelles, des trajets d'écoulement étant formés à travers chacun des éléments. Une barrière métallique dégradable peut être appliquée à au moins l'un des éléments, ce qui empêche ainsi temporairement un écoulement de fluide à travers les trajets d'écoulement, et fournit temporairement une isolation de pression radialement entre une partie intérieure et une partie extérieure de l'ensemble tamis. La dégradation de la barrière métallique peut permettre une communication fluidique et de pression radialement entre la partie intérieure et la partie extérieure de l'ensemble tamis.
