Abstract
A method and apparatus to affix a tool downhole in a cased wellbore, one embodiment comprising a tubular body with a slot along its length. A portion of the slot is V-shaped to accommodate a wedge with a corresponding V-shape. The outside of the tubular body has integral teeth. To set the apparatus, the wedge is driven into the V-shaped slot. This movement widens the slot and expands the diameter of the tubular body until it intersects with the casing. The teeth on the outside of the body bite into the casing wall to affix the tool to the casing.
Claims (15)
1. An apparatus for locating a well tool within a casing, comprising:
a tubular body having a central bore, an inner surface, an orientation surface, and an engaging surface;
said tubular body being expandable from a contracted position to an expanded position with said engaging surface frictionally engaging the casing.
a tubular body having a central bore, an inner surface, an orientation surface, and an engaging surface;
said tubular body being expandable from a contracted position to an expanded position with said engaging surface frictionally engaging the casing.
2. The apparatus of claim 1 wherein said engaging surface comprises teeth on an outer surface of said tubular body.
3. The apparatus of claim 1 wherein said engaging surface comprises an outer surface of said tubular body.
4. The apparatus of claim 1 further comprising a longitudinal slot on said body.
5. The apparatus of claim 1 wherein said bore is dimensioned to receive said well tool when said tubular body is in said expanded position.
6. The apparatus of claim 1 further comprising at least one groove formed on the inner surface of the body.
7. The apparatus of claim 1 further comprising a seal member disposed on said body to provide a sealing engagement with said casing.
8. The apparatus of claim 1 further comprising an actuation member to expand said tubular body from a contracted position to an expanded position.
9. The apparatus of claim 1 wherein said orientation surface comprises an upper point and opposite sides which taper downwardly.
10. The apparatus of claim 6 wherein said at least one groove is adapted to position said well tool within said apparatus.
11. A method of positioning a well tool within a cased borehole comprising:
lowering an expandable tubular member into the cased borehole;
expanding at least a portion of the expandable tubular member into frictional engagement with the cased borehole;
lowering the well tool into the cased borehole; and engaging orientation surfaces on the well tool and the expandable tubular member.
lowering an expandable tubular member into the cased borehole;
expanding at least a portion of the expandable tubular member into frictional engagement with the cased borehole;
lowering the well tool into the cased borehole; and engaging orientation surfaces on the well tool and the expandable tubular member.
12 The method of claim 11 wherein the expandable tubular member is lowered on a setting tool that performs the expanding step.
13. The method of claim 12 wherein the setting tool is hydraulically actuated.
14. The method of claim 11 further comprising performing a well operation with the well tool.
15. The method of claim 11 further comprising releasing the expandable tubular member from engagement with the cased borehole and removing the expandable tubular member from the cased borehole.
