Patent ID: 7416027

Claim:
An apparatus for radially expanding a tubular member, comprising: a tubular support member comprising: a first tubular support body defining a longitudinal passage; a first lug coupled to and extending from the first tubular support body in the radial direction; a second lug coupled to and extending from the first tubular support body in the radial direction; and an expansion cone support body coupled to the first tubular support body comprising: an N-sided tapered tubular support member; wherein each side of the multi-sided tapered tubular support member defines a T-shaped slot; N expansion cone segments movably coupled to the expansion cone support body, each comprising: an expansion cone segment body including arcuate conical outer surfaces; a first T-shaped retaining member coupled to the expansion cone segment body for movably coupling the expansion cone segment body to a corresponding one of the T-shaped slots of the expansion cone support body; and a second T-shaped retaining member coupled to the expansion cone segment body; a split ring collar assembly movably coupled to the exterior of the tubular support member comprising: a second tubular support body defining: N T-shaped slots for movably receiving corresponding ones of the second T-shaped retaining members of the expansion cone segments; and an L-shaped retaining member coupled to the second tubular support body; a first drag block assembly movably coupled to the tubular support member that comprises: a first drag block body defining: a slot for receiving and mating with the L-shaped retaining member of the split ring collar; and a first J-shaped slot for receiving the first lug; and one or more first drag blocks coupled to the first drag block body; a second drag block assembly movably coupled to the tubular support member that comprises: a second drag block body defining: a second J-shaped slot for receiving the second lug; and one or more second drag blocks coupled to the second drag block body; and first and second packer cups coupled to the tubular support member between the first and second drag block assemblies.
