Double-Way Shock Absorber

The two ways shock absorbers are used to simultaneously slow down or eliminate thevertical or horizontal shock from drill string. It can reduce the damage due to shocking to drill bit,drilling tool and surface drilling tool so as to enhance drilling speed and reduce drilling cost.

Working Principle

The torsion of bottom hole will be changed with changes in bit structure, formation and bitweight. When the drilling speed reaches up to a certain value, torque and resonance willbe happened to drill string. During rotation drilling, the lower part of drilling toolsimultaneously bear axially pressure and torque. When bit weight exceed the limit value,the drilling tool will produce a transverse bending (it means lose steadiness) and torquecan also make the drilling tool to lose steadiness to be turned into a twist shape.
