DOUBLE WAY SHOCK ABSORBER

TECHNICAL SUMMARY

JQ-YS double way hydraulic shock absorbers target axial and circumferential drill string vibrations in onshore/offshore drilling. They stabilize weight on bit (WOB) and torque to extend bit/downhole tool life while shielding surface equipment. These units boost rate of penetration (ROP) and cut costs, with standard API connections and a -40~120℃ operating range.
