Title (EN) FLOW-INDUCED EROSION-CORROSION RESISTANCE IN DOWNHOLE FLUID FLOW CONTROL SYSTEMS
(FR) RÉSISTANCE À L’ÉROSION-CORROSION INDUITE PAR ÉCOULEMENT DANS DES SYSTÈMES DE RÉGULATION DE DÉBIT DE FLUIDE DE FOND
Abstract:
(EN) Fluid flow control systems are configured to resist erosion-corrosion and minimize wall shear stress during injection or production. A fluid flow control system includes a base pipe with an internal passageway. A housing is positioned around the base pipe to define a fluid flow path between the filter component and the internal passageway. A flow control component is positioned within the fluid flow path in order to control fluid flow. A flow-induced erosion resistance component, which may take a variety of forms, is positioned within the fluid flow path to reduce and/or eliminate wall shear stress along the base pipe. As a result, erosion-corrosion of the bases pipe is reduced and/or eliminated altogether.
(FR) La présente invention concerne des systèmes de régulation de débit de fluide sont configurés pour résister à l’érosion-corrosion et réduire au minimum la contrainte de cisaillement de paroi pendant l’injection ou la production. Un système de régulation de débit de fluide comprend un tuyau de base avec un passage interne. Un boîtier est positionné autour du tuyau de base pour définir un trajet d’écoulement de fluide entre le composant de filtre et le passage interne. Un composant de régulation de débit est positionné dans le trajet d’écoulement de fluide afin de réguler le débit de fluide. Un composant de résistance à l’érosion induite par écoulement, qui peut prendre différentes formes, est positionné dans le trajet d’écoulement de fluide pour réduire et/ou éliminer une contrainte de cisaillement de paroi le long du tuyau de base. En conséquence, l’érosion-corrosion du tuyau de base est réduite et/ou totalement éliminée.
