A deformable well screen for preventing migration of solid particles into a hydrocarbon production well comprises at least one substantially tubular filter layer of which the sieve opening size remains fairly constant or gradually changes in a predetermined and uniform manner during or after expansion and/or other deformation of the screen. Optionally the screen comprises a series of circumferentially scaled filter segments (4) that are arranged around an expandable slotted tube (3), an expandable slotted tube of which the slots are filled with resin coated granules, an expandable slotted tube with micro-slots, an assembly of woven metal wire screens that are sintered together and for a synthetic geotextile.
Ce filtre déformable pour puits, destiné à empêcher la migration de particules solides dans un puits de production d'hydrocarbures, comprend au moins une couche filtrante sensiblement tubulaire dont la dimension d'ouverture de tamis reste assez constante ou change graduellement de façon prédéterminée et uniforme pendant ou après dilatation et/ou autre déformation du filtre. Le cas échéant, le filtre comprend une série de segments (4) filtrants proportionnés de manière circonférentielle et disposés autour d'un tube (3) rainuré extensible, ledit tube dont les rainures sont remplies de granules enrobés de résine, un autre tube rainuré extensible et pourvu de micro-fentes, ainsi qu'un assemblage de filtres en fil métallique tissé, frittés ensemble et/ou réalisés dans une étoffe géotextile synthétique.
