Downhole tool

Torsional punching tool

Torque impingers eliminate one or more vibrations (transverse, longitudinal, and torsional) that may occur during downhole drill bit movement, keeping the torque of the entire drill string stable and balanced, subtly converting mud fluid energy into torsional, high frequency, uniform and stable mechanical impact energy that is directly transmitted to the PDC bit, ensuring continuity between the bit and bottom hole.

Hydraulic oscillator moving and static valve

The hydraulic oscillator takes the drilling fluid as the power source, converts the liquid energy into mechanical energy, and transmits it to the dynamic valve plate of the flow valve assembly through the cardan shaft assembly, so that the flow holes of the dynamic valve plate and the static valve plate are interleaved with each other, resulting in changes in the flow area. Each small change in the action will produce a corresponding continuous change in the hydraulic surge or depressurization wave at the valve shaft assembly. The pressure of the water blow booster or step-down wave acts on the piston of the pressure damping assembly. The resulting gentle downward force is applied to the bit as bit weight, forcing the bit to break rock into the formation and increasing the rate of penetration. The main specifications of dynamic and static valves are: 73, 127, 172, 203, etc., which can be made according to customer requirements.
