A tool for retrieving metal debris from a wellbore has a plurality of magnet assemblies spaced longitudinally along a tool body (10). Each magnet assembly has a magnet member (42), which forms a primary debris settling area (70). Each magnet member is protected by a magnet protector. A secondary debris settling area is formed between a magnet and an adjacent magnet protector to allow utilization of the residual magnetic force created by the magnet members. The secondary settling area occupies at least half of the surface area of the primary settling area.
L'invention concerne un outil permettant de récupérer des débris métalliques d'un puits de forage. Cet outil comporte une pluralité d'ensembles aimants espacés de manière longitudinale le long d'un corps d'outil (10). Chaque ensemble aimant comporte un élément aimant (42) qui forme une zone principale d'accumulation (70) des débris. Chaque élément aimant est protégé par un protecteur d'aimant. Une zone secondaire d'accumulation des débris est formée entre un aimant et un protecteur d'aimant adjacent, pour permettre l'utilisation de la force magnétique résiduelle créée par les éléments aimants. Cette zone secondaire d'accumulation occupe au moins la moitié de la surface de la zone d'accumulation principale.
