Product Details
Introduction
A hydraulic oscillator can be used to improve the outcome of WOB transmission, mitigate the risk of sticking between drilling tools, and reduce stick-slip vibration, thus improving the rate of penetration and drilling efficiency.
- Suited to improving the effectiveness of WOB transmission during drilling by means of self-generated longitudinal vibration.
- Reduce the friction between the bottom drilling tool and the borehole.
- Capable to work under various drilling modes.
- Applicable in the scenarios where dynamical drilling tools are used for its effectiveness in improving the outcome of WOB transmission, mitigating the risk of sticking between drilling tools, and reducing stick-slip vibration, thus improving the rate of penetration and drilling efficiency.
