Title
(EN) METHOD FOR DOWNHOLE SCREEN MANUFACTURING
(FR) PROCÉDÉ DE FABRICATION D'UN TAMIS DE TROU D'EXTRACTION
Abstract
(EN)
A method of making a screen for downhole use uses mesh screen layers that are diffusion bonded to each other. The ends that will overlap to make a seam when the sheets that are attached together are rolled into a tube are compressed before the tube shape is created or thereafter when the tube shape and an inner base pipe are drawn through a die to join the seam made by the overlapping edges. Because of the compression of the edges, when they overlap to form a tube the wall thickness at the overlap is about the same as the remaining thickness of the screen portion. Optionally, a resilient material can be compressed into the open areas of the screen portions that will be overlapped to make the generally longitudinally oriented seam. The seam can be parallel to the screen axis or spiral around it. The outer perforated shroud provides a compressive force that maintains a barrier resistant to flow of sand particles between the seam overlapping surfaces as the outer perforated shroud, filtration tube and inner base pipe assembly is drawn through a die.

L'invention divulgue un procédé de fabrication d'un tamis pour un trou d'extraction qui utilise des couches de tamis à mailles qui sont liées les unes aux autres par diffusion. Les extrémités qui se chevaucheront pour former une couture lorsque les feuilles qui sont attachées les unes aux autres sont enroulées en un tube sont comprimées avant que la forme de tube soit réalisée, ou plus tard lorsque la forme de tube et le tuyau de base intérieur sont étirés à travers une filière pour joindre la couture formée par les bords qui se chevauchent. Grâce à la compression des bords, lorsqu'ils se chevauchent pour former un tube, l'épaisseur de paroi à l'endroit du chevauchement est approximativement identique à l'épaisseur restante de la partie de tamis. Optionnellement, une matière élastique peut être comprimée dans les régions ouvertes des parties de tamis qui se chevaucheront pour former la couture orientée de façon essentiellement longitudinale. La couture peut être parallèle à l'axe du tamis ou former une spirale autour de celui-ci. Le carénage extérieur perforé crée une force de compression qui constitue une barrière qui résiste à l'écoulement de particules de sable entre les surfaces de couture qui se chevauchent lorsque l'ensemble de carénage perforé, de tube de filtration et de tuyau de base intérieur est étiré à travers une filière.
