Title: Method and apparatus for absorbing shock

Abstract

This patent describes a tubing conveyed perforating gun tool string assembly for use in an earth borehole, which consists of: a shock sensitive component coupled to the tool string which is to be isolated from a portion of the shock to the assembly; a tubing conveyed perforating gun coupled to the tool string; and means for damping a portion of the longitudinal and radial accelerators of the shock sensitive component due to the detonation of the tubing conveyed perforating gun. A method of minimizing the transfer of shock caused by the detonation of a tubing conveyed perforating gun to other components in a tool string, the tubing conveyed perforating gun being releasably connected to the tool string, the tool string extending through a portion of a well bore, the method comprising the steps of: mounting a longitudinal shock absorber in the tool string on a first side of the tubing conveyed perforating gun to absorb at least a portion of the longitudinal shock to the tool string when the tubing conveyed perforating gun is detonated; and mounting a radial shock absorber in the tool string to absorb at least a portion of the radial shock to the tool string whenmore » the tubing conveyed perforating gun is detonated.« less
