Recyclable Hydraulic Pressure Whipstock

With the growing of directional well and horizontal well technology, as the extension and development of directional well technology, branch Wells was taken more and more attention. Recyclable whipstock is the key tools in branch well drilling technologies. It plays a vital role for branch well drilling and completion.

The recyclable whipstock has simple operation, sealing strong, high recovery rate, reusable advantages etc.
The recyclable whipstock have three parts: whipstock, circulation flushing valve and recovery tool.


  • Whipstock

Whipstock adopts hydraulic seat sealing way, strong seat sealing, easy operation. The slant face is cambered surface use hardening treatment, when window cutting, the milling taper highly coincides with the slant face, drilling pressure can be controlled easily, decreased choke off drilling and bit bouncing. Tool internal self-locking mechanism will be improved, using the axial and circumferential all-around self-locking, greatly improve the reliability of the tool.

  • Circulation Flushing Valve

Circulation Flushing Valve mainly used for liquid connecting, indirect flushing and direct circulation pressure sealing when tools are descending.Special internal designed diversion mechanism, guarantee the liquid connecting smoothly when tools are descending and flushing, avoid the solid  particles and impurities within the pipe column setting at the inside of whipstock, improve the reliability of tool use.



  • Recovery tool

Recovery tool adopts double salvage agencies, institutions independently and interconnected, greatly improve the success rate of recovery tool.
