ABSTRACT:
An improved slip assembly is provided for grasping the interior wall of a well conduit to secure a tool against longitudinal movement. Interengaging means, such as upper and lower slip rings surround the tool and have T-shaped ears projecting from the opposed lower and upper ends of the upper and lower slip rings, respectively. Each ear cooperates with a T-shaped slot formed in a wider end of a wedge-shaped slip element to retain a plurality of such slip elements in side-by-side relationship about the periphery of the tool. At least one of the slip elements has wickers or teeth formed on the outwardly facing surface thereof. Movement of a setting means forces the upper slip elements in a direction with respect to the lower slip elements such that the slip elements are forced outwardly until the wickers engage the interior wall of the well conduit to secure the tool on the well conduit. When all of the slip elements are provided with wickers the slip assembly will provide 360.degree. contact with the interior of the well conduit, which more evenly distributes the stress in the conduit at the point of slip contact.
