1 DOWNHOLE MACHINING SYSTEM AND METHOD US14894319 2014-06-13 US20160130904A1 2016-05-12 Tomas Sune ANDERSEN
The present invention relates to a downhole machining system (1) for machining a casing (2) in a borehole in a well having a top. The downhole machining system comprises a first tool part (4) having an axial extension (5) and an anchoring section (6); a second tool part (7) adapted to rotate and move axially in relation to the first tool part, the second tool part comprising a machining bit (8) being movable in a direction radial in relation to the axial extension; a first actuator (10) comprising an electrical motor (11A) for axially moving the second tool part in relation to the first tool part; a second actuator (12) comprising an electrical motor (13) for rotating the second tool part in relation to the first tool part; and a third actuator (14) comprising an electrical motor (11b) for rotating the bit. At least one of the actuators comprises a gear (15) for changing a rotational speed of a rotor of the motor.
