Method and apparatus for supporting a downhole component in a downhole drilling tool

摘要

An apparatus for supporting a retrievable downhole component within a drill collar of a downhole drilling tool deployed from a rig into a wellbore penetrating a subterranean formation is provided. The apparatus includes a sleeve that is positionable about the downhole component and is within said drill collar. The sleeve is adapted to limit the lateral movement of the downhole component. The sleeve is formed of a series of fins or is lined with an energy absorbing material which protects the downhold component from shock and vibration while at the same time, allowing the component to be retrieved should the drill string become stuck in the borehole.
