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.

Patentanspruch: Fangwerk:zeug zum Entfernen eisenhaltiger Spane aus verrohrten Tiefbohrlöcbern, das mit ringförmigen Permanentinagneten und einer Einrichtung zum Aufnehmen der Späne ausgerüstet ist, dadurch gekennzeichnet, daß die ringfõrmigen Permanenanagnete (1) jeweils eine bezüglich der Längsachse des Werkzeugs radial verlaufende Zugkraft aufweise, daß das Werkzeug zusätzlich mit kreisförmigen Drahtbursten (23 zum Abstreifen der Späne von der Innenwand der Futterrohre versehen ist, und daß als Einrichtung zum Aufnehmen der abgestreiften Spänen ein im unteren Teil des Werkzeugs angeordneter,- aus nicht rnagnetischem Stahl bestehender Fangkorb (3) vorgesehen ist Die Erfindung betrifft ein magnetisches Fangwerkzeug für die Entfernung eisenhaltiger Späne aus verrohrten Tiefbohrlöchern nach dem Oberbegriff des Patentanspruchs.Claim: Catcher: tool for removing iron-containing chips cased deep boreholes with ring-shaped permanent magnets and a device is equipped for receiving the chips, characterized in that the annular Permanent magnets (1) each one radially with respect to the longitudinal axis of the tool running tensile force that the tool also has circular wire brushes (23 is provided for stripping the chips from the inner wall of the casing, and that as a device for receiving the stripped chips a in the lower part of the - made of non-magnetic steel collecting basket (3) The invention relates to a magnetic fishing tool for removal ferrous chips from cased deep boreholes according to the preamble of the claim. Nach Frãsarbeiten, Bohrlochsablenkungen und ãhnlichen Arbeiten befinden sich im Bohrloch eisenhaltige Späne, welche entfernt werden müssen, da sie bei der endgültigen Fertigstellung der Färdersonde und bei der Produktion von Erdöl oder F.rdgas Störungen verursachen. Ein Teil dieser Spane befindet sich, bedingt durch schwache magnetische Eigenschaften, an der Innenwandung der Verrohrung. Bedingt durch diesen Umstand und durch ihr hohes spezifisches Gewicht, können diese Späne auch nicht durch Spülen entfernt werden. After milling work, borehole deflections and similar work are located there are iron-containing chips in the borehole, which must be removed because they are in the final completion of the feed well and in the production of petroleum or Natural gas can cause disruptions. Part of this chip is due to weakness magnetic properties, on the inner wall of the piping. Due to this Due to their high specific weight, these chips cannot either can be removed by rinsing. Nach dem Stande der Technik ist es gemäß der FR-PS 11 67 537 und der US-PS 29 65 406 bekannt, zur Erfüllung dieser Erfordernisse ringförmige bzw. radial angeordnete Magnete mit einer auf die Längsachse bezogen radial wirkenden Zugkraft zu verwenden. According to the prior art, it is according to FR-PS 11 67 537 and the US-PS 29 65 406 known to meet these requirements annular or Radially arranged magnets with one acting radially in relation to the longitudinal axis To use traction. Gemäß der US-PS 38 14 180 ist es bekannt, zum Abstreifen von an der Innenwand der Verrohrung haftenden Verunreinigungen am Fangwerkzeug geeignete Kratzer und unterhalb davon einen Fangkorb für die Verunreinigungen vorzusehen.According to US-PS 38 14 180 it is known for stripping on the Inner wall of the piping adhering impurities to the fishing tool suitable scratches and below it to provide a collecting basket for the impurities. Der Erfindung liegt die Aufgabe zugrunde, pro Seilfahrt größere Mengen Späne von der Rohrinnenwand zu lösen und zu Tage zu bringen. Diese Aufgabe wird erfindungsmäßig durch die im Patentanspruch gekennzeichneten Merkmale gelöst Die mit der Erfindung erzielbaren Vorteile bestehen darin, daß pro Seilfahrt erheblich größere Mengen an Spänen zu Tage gebracht werden und eine bessere Säuberung der Rohrinnenwand erreicht wird. The invention is based on the task of producing larger quantities per cable trip To loosen chips from the inner wall of the pipe and to bring them to light. This task will according to the invention solved by the features characterized in the claim The advantages that can be achieved with the invention are that considerably per cable trip larger amounts of chips are brought to light and a better cleaning of the Inner pipe wall is reached. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. An embodiment of the invention is shown in the drawing and is described in more detail below.
