Shock tool is designed to reduce the impact of vibrations on the elements of the bottom of the drill string, and to absorb shocks and vibrations acting on the string in the process of drilling oil and gas wells.
By isolating vibration from the bottom hole assembly caused by the drilling operations, the shock tool reduces the probability of a drill string failure or and electronic
components due to fatigue destruction.
Shock tool design ensures efficient operation under various combinations of axial loads on bit and reduces fluctuation/spikes in mud flow rates and pressures.
When drilling a well using a downhole drive shock tool installed in the BHA directly above the bottom hole drive, when drilling in a rotary mode – above the bit.
