Title (EN) DUAL-POLE MAGNETIC ATTRACTION DOWNHOLE MAGNETIC RETRIEVAL APPARATUS
(FR) APPAREIL DE RÉCUPÉRATION MAGNÉTIQUE DANS UN FORAGE À ATTRACTION MAGNÉTIQUE BIPOLAIRE
Abstract: front page image
(EN)A magnetic retrieval tool used for collecting metallic debris and material from within a wellbore or other surrounding downhole tubular. The tool includes a tool mandrel with a removable insert which contains one or more magnets. The insert is formed such that both the north and south magnetic poles of the one or more magnets are able to attract metallic debris.
(FR)L'invention porte sur un outil de récupération magnétique destiné à collecter des débris et matières métalliques de l'intérieur d'un forage ou d'un autre élément tubulaire de forage qui l'entoure. L'outil comprend un mandrin d'outil possédant un insert amovible qui contient un ou plusieurs aimants. L'insert est formé de telle manière que les pôles magnétiques nord et sud de l'un des aimants ou de plusieurs des aimants soient capables d'attirer des débris métalliques.
