Hydraulic Oscillator-Effectively Improve Weight On Bit Transfer
•The tool is powered by drilling fluid, which causes the drill string to produce high-frequency axial vibration, thereby changing the static friction of the sliding drilling tool into dynamic friction. •This tool can solve the "supporting pressure" of directional horizontal well, improve the weight on bit transfer, increase the service life of the drill bit, improve directional performance, increase the mechanical penetration rate and the penetration of a single run.
Description
Applications
It is suitable for directional well and horizontal well drilling construction, improving the drilling pressure transmission effect and improving the tool face control efficiency.
Features&Benefits
Two-stage piston with 70% increased thrust.
Low pressure consumption
The ambient temperature is up to 160°C.
Water-based and oil-based muds are universal.
