Abstract
A magnetic catch tool serves to remove ferriferous chips, arising from drilling and cutting work, from cased deep drill holes. Since these chips can cause problems during the final completion of the output wells and during the production of crude oil or natural gas, they must be removed to the greatest possible extent and as quickly as possible. This is made possible by the tool being provided with several annular permanent magnets (1) with a pulling force running radially with regard to the longitudinal axis, by the tool being additionally equipped with circular wire brushes (2) for wiping the chips from the inner wall of the casing, and by a catch basket (3) made of non-magnetic steel being arranged at the bottom part of the tool for receiving the chips. <IMAGE>
Description
Auf einer aus verschraubten Einzelteilen bestehenden Stange befinden sich die ringförmigen Permanentmagnete (1), die ringförmigen Drahtbürsten (2) und der Fangkorb aus nicht magnetischem Stahl (3). Am Oberteil befindet sich ein Schraubgewinde zum Anschluß einer Seilflasche für ein Bohrlochlotseil. Located on a rod consisting of bolted individual parts the ring-shaped permanent magnets (1), the ring-shaped wire brushes (2) and the catcher made of non-magnetic steel (3). There is a screw thread on the upper part for connecting a rope block for a borehole plumbing rope.
