Abstract
An anchoring tool for positioning a downhole tool within a wellbore conduit is described herein. The anchor tool uses replaceable blades having protrusions that are configured to align with corresponding grooves in an anchor sub receptacle that is located at a known position along the wellbore conduit. The blades of the anchor tool are configured to move radially relative to the anchor tool body until the anchor tool is aligned with a compatible anchor sub. When the anchor tool and the compatible anchor sub are aligned, the protrusions of the anchor tool blade extend into the grooves of the anchor sub receptacle and a locking mechanism within the anchor tool inhibits further radial movement of the blades. A downhole tool connected to the anchor tool can therefore be positioned at a precise location relative to the known location of an anchor sub receptacle.
