Downhole tool system, method, and borehole system
A downhole anchor system, including a housing, a downhole force multiplier cartridge (DFMC) disposed in contact with the housing, and an anchor slip operably connected to the downhole force multiplier cartridge. A downhole system including a mill including a motive force generator, a whipstock connected to the mill, an anchor connected to the whipstock, a downhole force multiplier cartridge (DFMC) operably connected between the generator and the anchor, the DFMC multiplying a force supplied by the force generator and conveying that multiplied force to the anchor. A method for setting a downhole tool, including generating a force with a force generator, multiplying the force with a DFMC, applying the multiplied force to a settable downhole tool, and setting the tool with the multiplied force. A borehole system including a borehole, a string in the borehole, and a downhole anchor system disposed within or as a part of the string.
1 . A downhole anchor system, comprising:
a housing;
a downhole force multiplier cartridge (DFMC) disposed in contact with the housing, the DFMC having a force input member and a force output tether, the force input member configured to be connected to a force generator and to multiply a force generated by the force generator to be output by the force output tether; and
an anchor slip operably connected to the downhole force multiplier cartridge.
2 . The system as claimed in claim 1 , wherein the DFMC comprises:
a frame; and
a plurality of pulleys disposed in the frame.
3 . The system as claimed in claim 2 , wherein at least one of the pulleys of the plurality of pulleys includes more than one groove.
4 . The system as claimed in claim 2 , wherein each of the pulleys includes a rotational axis, and wherein the rotational axis of at least one of the pulleys of the plurality of pulleys is displaceable relative to the rotational axis of another of the pulleys of the plurality of pulleys.
5 . The system as claimed in claim 2 , wherein at least one of the pulleys of the plurality of pulleys includes a tether mount.
6 . The system as claimed in claim 5 , wherein the tether mount includes a swivel.
7 . The system as claimed in claim 2 , wherein the DFMC further includes a tensioner pulley.
8 . The system as claimed in claim 1 , wherein the housing incudes a whipstock.
9 . A borehole system comprising:
a borehole;
a string in the borehole; and
a downhole anchor system as claimed in claim 1 disposed within or as a part of the string.
