Claims24
A slip for use in the anchoring device on a well tool comprising:
- a wedge shaped body and teeth on the exterior of the body, the teeth being formed from a ring segment mounted on and extending from the exterior of the body.
A slip assembly for use in the anchoring device on a well tool comprising:
- a segmented annular body and at least one circumferentially extending tooth on the exterior of each body segment, the tooth being formed from ring segments mounted on and extending from the exterior of the body segments.
A tool for use in a tubular member at a subterranean location of a well comprising:
- a mandrel;
- an anchoring device connected to the mandrel to engage the wall of the tubular member and anchor the mandrel in place in the well, the anchoring device comprising at least one slip mounted on the mandrel to move from a retracted run position to a set position engaging the tubular member;
- and
- a ring segment mounted on the slip with at least a portion of the ring segment extending from the exterior surface of the slip as a tooth for engaging the tubular member.
A method of forming an anchoring device for use in contacting the wall of a well tubing at a subterranean location comprising the steps of:
- forming an annular body of corrosion resistant material,
- forming at least one circumferential extending groove in the external surface of the body, and
- installing at least a portion of a ring of spring tempered steel in the groove.
