Apparatus for cleaning the inner wall of wellbore tubulars, and for capturing downhole debris in the wellbore An elongated, tubular central mandrel has threaded connections on either end for makeup into a tubular string The mandrel has recesses on its outer circumference into which split rings are mounted Various service elements are then attachable to the central mandrel, by sliding them over the mandrel and holding them in place with stabilizer elements which connect to the split rings Different embodiments of the service elements include a brush assembly, a junk basket, and a magnet The stabilizer elements may be mounted onto the split rings so as to either be rotationally locked with respect to the mandrel, or so as to be capable of rotating with respect to the mandrel, since th service elements are held in place on the central mandrel by the stabilizer elements.

Différents modes de réalisation des éléments de service comprennent un assemblage de brosse, un panier à sédiment, et un aimant. Les éléments stabilisateurs peuvent être montés sur les bagues fendues afin d'être verrouillés de façon rotative par rapport au mandrin ou afin d'être capables de tourner par rapport au mandrin, du fait que les éléments de service sont maintenus en place sur le mandrin central par les éléments stabilisateurs.
