Abstract

Appareil et méthode pour contrôler la production de sable dans un puits de forage. L’appareil comprend un tuyau de base dont la section centrale est perforée pour permettre un flux de liquide entre l’extérieur et l’intérieur du tuyau de base; un filtre hélicoïdal enroulé directement entoure de la paroi extérieure de la section centrale du tuyau de base, le filtre étant doté de perforations pour permettre le flux de liquide tout en prévenant la pénétration de sable dans les ouvertures; et une première et seconde bague d’extrémité pour raccorder la première et la deuxième extrémité du filtre, respectivement, au tuyau de base. L’appareil est formé d’une plaque métallique perforée enroulée hélicoïdalement autour de la section centrale du tuyau de base pour former le filtre; les bords aboutés du filtre sont soudés pour créer des joints hélicoïdaux; et le filtre est fixé au tuyau de base par le soudage du premier et second anneaux d’extrémité qui joignent le filtre au tuyau de base.
