DOWNHOLE ANCHOR

摘要

The disclosure provides a downhole anchoring apparatus for use in a downhole tool. An example downhole anchoring apparatus may include a housing with a hub provided within the housing. The hub may be arranged to rotate in a bidirectional fashion about a longitudinal axis. The downhole anchoring apparatus may also include a deployment linkage. The deployment linkage may be coupled to the hub by a hinge so that when the hub is rotated in a first direction, a distal end of the deployment linkage is extended radially outward from the central axis, and when the hub is rotated in a second direction, the distal end of the deployment linkage is retracted toward the central axis.

1. A downhole anchoring apparatus for use in a downhole tool, the downhole anchoring apparatus comprising:
a housing; a hub rotatably arranged on a longitudinal axis in the housing; a deployment linkage coupled to the hub by a hinge so that a distal end of the deployment linkage extends radially outward from the longitudinal axis as the hub is rotated in a first direction and radially retracts toward the longitudinal axis as the hub is rotated in a second direction; a slip coupled to the distal end of the deployment linkage that engages an inner surface of the wellbore casing in response to radial extension of the deployment linkage and disengages the inner surface of the wellbore in response to retraction of the deployment linkage.
