CA 2280916

A prepacked well screen has concentric inner (10) and outer (11) fiber reinforced composite tubes with a granular filter medium (13) in the annulus between the inner (10) and outer (11) tubes. The walls of the tubes are slotted (12) for passing fluid through the slots (12) and the filter medium (13). Each end of the inner tube (10) extends beyond the adjacent end of the outer tube (11) and has a male thread (16). A connection is made to an adjacent well screen or other tube by a female coupling member (18) threaded onto the male thread (16). An advantage of the design is that the coupling member (18) connected to the inner tube (10) has an outside diameter approximately the same as the outside diameter of the outer tube (11).

L'invention concerne un filtre de puits à joint lisse préfabriqué comportant des tubes concentriques en composite renforcé de fibres, intérieur (10) et extérieur (11), pourvus d'un milieu filtrant (13) granulaire situé dans l'espace annulaire entre les tubes intérieur (10) et extérieur (11). Les parois des tubes sont fendues (12) afin de laisser passer un fluide à travers les fentes (12) et le milieu filtrant (13). Chaque extrémité du tube intérieur (10) s'étend au-delà de l'extrémité adjacente du tube extérieur (11), et est dotée d'un filetage mâle (16). Une connexion est établie avec un filtre de puits ou un autre tube adjacent au moyen d'un élément de couplage femelle (18) vissé sur le filetage mâle (16). Un avantage que présente cette configuration est que l'élément de couplage (18) connecté au tube intérieur (10) présente un diamètre extérieur approximativement égal à celui du tube extérieur (11).
