Downhole Jarring Tool Two Way Shock Sub, Shock Absorber 4 3/4''~11''
Two-Way Shock Sub should be mounted on drill string which is near the bit. It can slow or sorbs the longitudinal bounce and peripheral torque impact of drill bit (drill string) simultaneously. It should realize the best fitting of drill pressure and rotation rate as to reduce the drill cost and improve the drilling efficiency. It can be used for the drill-in or coring of hard layer, gravel layer and soft-hard interlayer. It is an effective shock absorbing device, so that it helps to reduce drill string connection fatigue and prolong drill string life. It can be used to reduce or eliminate both transversal and longitudinal vibration of drill string, thus it helps maintain normal weight-on-bit (WOB) and torque.
