Abstract
Shock tools can include a rotary top drive box in threaded connection with an outer tube. A center plate tube can run through the center of the shock tool to provide a pathway for drilling fluid and/or mud to flow to the drill bit. A bottom tube socket box holding head can be attached to the outer tube and the center plate tube can be connected to a bottom drive socket. The bottom tube socket box holds a portion of the bottom drive socket within the outer tube. The center plate tube can be slidably engaged with the rotary top drive box. Multiple compression plates separated by compression pads are located in the tool to dampen the shock load by distributing the load across each of the multiple pads, thereby minimizing the load on any individual pad. This arrangement allows for higher load dampening lower failure rates.
