Abstract

Implementations of the present invention relate generally to methods, systems, and apparatus for absorbing vibration and shock impulses created during drilling operations. In particular, implementations of the present invention include drill-string shock absorbers adapted to absorb longitudinal forces produced during a drilling operation. For example, drill-string shock absorbers in accordance with at least one implementation of the present invention include a generally cylindrical housing having a first end and a second end coupled together by a radially interlocking joint. Such a configuration can reduce mechanical failure and increase the operating life of the shock absorber by transmitting torsional forces directly between the ends of the housing and reducing stresses from being transferred to fastening means securing the first and second ends of the cylindrical housing together.
