Hydraulic oscillator
With the continuous development of drilling technology, the number of extended reach wells and long horizontal wells is increasing. During the drilling process of horizontal wells, problems such as high frictional resistance and underpressure not only seriously affect the mechanical penetration rate of horizontal wells, but also easily cause downhole faults such as differential pressure sticking. Especially during sliding drilling, it is impossible to apply true and effective bit pressure to the drill bit, reducing drilling efficiency and extending the well construction cycle.
The hydraulic oscillator developed by Tianhe Petroleum Group optimizes structural design and performance parameters through virtual fluid simulation and other technologies, which is suitable for various complex drilling conditions and effectively solves the above problems.

Product Features
- Hydraulic oscillators can effectively reduce the friction between the drilling tool assembly and the wellbore during sliding drilling and effectively improve the transmission of weight on bit.
- Reduce downhole torsion, reduce lateral vibration, and increase mechanical penetration rate.
- Directional drilling efficiency can be greatly improved, allowing for smoother borehole drilling.
- Hydraulic oscillators can be used for vertical wells, motor guided drilling, extended reach wells, and shale gas reservoir drilling.
- It can solve problems such as underloading, jamming, and poor control of the drill bit on the tool surface. Improve the control of directional drilling tool surface and effectively improve the directional ability.
- The pressure pulse generated by the hydraulic oscillator does not interfere with the MWD signal and does not damage the MWD instrument.
- The hydraulic oscillator has good adaptability to conventional PDC bits and roller bits.
