Abstract
The present invention includes devices for absorbing shock in a tool string within a borehole. These components may serve together in a variety of configurations to form a shock absorbing system. A longitudinal shock absorber is connected in the tool string. The longitudinal shock absorber includes compressible members utilized to damp longitudinal movement. A radial shock absorber is connected in the tool string. The radial shock absorber includes resiliently mounted contact pads for contacting the sides of the borehole to damp radial movement. A carrier assembly is utilized to provide a shock absorbing mounting for particularly delicate components such as gauges, and to damp any shock which might be transmitted thereto from either a radial or longitudinal direction.
