A filter for subterranean environments includes an inner support member, a filter body containing a filter medium disposed around the inner support member, and at least one end connector connected to a lengthwise end of the filter body and sealed against the inner support member without being welded to the inner support member. The end connector may be restrained from movement relative to the inner support member in a lengthwise direction of the inner support member, without being welded to the inner support member, to resist axial forces acting on the filter during installation or operation in a well. Alternatively, the end connector may be capable of movement with respect to the inner support member in a lengthwise direction of the inner support member to enable the filter to undergo thermal expansion without damage to the filter body or other portions of the filter.

Le filtre utilisé sous terre inclut un élément de support intérieur, un corps de filtre renfermant un matériau filtrant placé autour de l'élément de support intérieur et, au moins, un connecteur d'extrémité fixé à une extrémité longitudinale du corps de filtre et scellé sur l'élément de support intérieur sans y être soudé. Le connecteur d'extrémité peut être maintenu immobile par rapport à l'élément de support intérieur dans le sens longitudinal dudit élément, sans être soudé à ce même élément, afin de résister aux forces axiales agissant sur le filtre pendant l'installation ou l'utilisation dans un puits. Le connecteur d'extrémité peut aussi bouger par rapport à l'élément de support intérieur dans le sens longitudinal de cet élément pour permettre au filtre de subir une expansion thermique sans endommager le corps de filtre ou les autres parties du filtre.
