Patent
·
OSTI ID:5152310
This patent describes a slip mechanism for anchoring a well tool having a cylindrical body from the inside of a well conduit. It comprises a cylindrical wedge member positioned on the outside of the body, the wedge member including in its outer surface a plurality of circumferential grooves extending entirely around the member, the grooves including an outwardly tapered side, a cylindrically shaped split slip member positioned outside of the wedge member, the slip member including a plurality of teeth on its outer surface, the slip member including ridges on its inner surface mating with and coacting with the grooves on the wedge member, the ridges including a tapered side coacting with the tapered sides of the wedge member for providing radial displacement of the slip when the wedge member and slip are moved axially relative to each other, the circumstantially grooves form a helical thread and the ridges from a helical mating surface, and the slip member includes a plurality of circumferentially spaced segmented slips for providing increased contact area with the inside of the well conduit and increasing the load carrying capacity of the slip mechanism.
