Bonded Segmented Slips

摘要

A slip assembly for a downhole tool, such as a bridge plug, has a slip body composed of independent segments. The segments are affixed together along their longitudinal sides by a bond, which can be composed of thermoplastic or thermoset resins, an elastomer, epoxy adhesives, bonding agent manufactured using ceramic, metallic agent, or a combination of these. The surface area over which the bonding agent is applied can be controlled for a particular implementation. Thus, more or less of the longitudinal sides of the segments can be bonded to other segments. This provides greater control of the required force to break the bond itself, which can be tailored as desired.

主权项

1. A downhole apparatus, comprising:
a plurality of segments being independent from one another and being disposed side-by-side about the downhole apparatus, each side of the segments bonded by bonding material to the side of an adjacent one of the segments, wherein the segments separate from one another at the bonded sides when expanded outward from the downhole apparatus.
