Abstract
A downhole anchor mechanism for use in downhole tools. The downhole anchor mechanism generally consists of a plurality of sliders that pivot outwardly from a downhole tool body to engage distal ends thereof against a well casing. The sliders are operatively engaged within faceted cavities associated with the tool body, which creates load components that act in a tangential direction, allowing a thin-walled tool body to withstand increased holding force.
Claims10
An anchor mechanism configured for use with a downhole tool, comprising:
- a member with a plurality of fingers;
- a channel positioned between the plurality of fingers, the channel including a first portion and a second portion, wherein a minimum width across the channel between the first portion and the second portion is narrower than a distal end of the channel across the second portion of the channel and a proximal end of the channel across the first portion of the channel, the second portion included angled walls extending to the minimum width;
- a slip configured to move along the angled walls of the second portion of the channel from the distal end of the channel toward the first portion of the channel, wherein a fluid flow path is created between the first portion of the channel and an inner surface of a first end of the slip after the first end of the slip moves radially outward and axially along the angled walls of the second portion of the channel, wherein when the first end of the slip moves along the angled walls of the second portion of the channel the first end of the slip is positioned radially outside the first portion of the channel.
