Abstract: 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.

Abstract translation: 用于井下工具（例如桥塞）的滑动组件具有由独立段组成的滑动体。 这些片段通过可由热塑性树脂或热固性树脂构成的粘合剂，弹性体，环氧树脂粘合剂，使用陶瓷，金属剂或这些组合制成的粘合剂，沿其纵向边固定在一起。 可以对特定实施例来控制施加粘合剂的表面积。 因此，可以将这些段的多个纵向侧面或多或少地结合到其他段。 这提供了更好地控制所需的力以破坏粘结本身，这可以根据需要进行调整。
