Patent

CA 2230425

A slip guidance system is provided to prevent a slip or series of slips from becoming skewed as they are extended toward the casing. The slip has a plurality of parallel tabs on each side which interact with a plurality of dovetails in the cone which retains the slips. As the slips are extended, the parallel tabs ride up in the parallel dovetails, thus preventing the slip from becoming skewed as it is extended toward the casing.

Système de guidage des coins utilisé pour empêcher un coin ou une série de coins de devenir obliques au moment où ils sont déployés vers le tubage. Le coin comporte une série de languettes parallèles de chaque côté qui s'engagent dans une série de queues d'aronde sur le cône qui retient les coins. Au fur et à mesure que les coins sont déployés, les languettes parallèles s'élèvent dans les queues d'aronde parallèles et elles empêchent le coin de devenir oblique lorsqu'il est déployé vers le tubage.
