Our deflecting tools have two types: anchor type deflector and hydraulic setting slip type deflector. hydraulic setting slip type deflector supply accurate orientation solid seat sealing advantages etc. When reservoir area casing seriously damaged or reservoir sand buried or collapsed, the well can't production, in order to use the upper casing, reduce the cost of drilling, can make window cutting sidetracking on the upper casing above oil layer, to form a new hole for drilling. Internal window sidetracking is a crucial method when drill a deviated well with seriously damaged bottom casing, to use the upper casing, make the well build up production capacity. Window sidetracking tools mainly including deflector and window milling taper.

Many oil fields in domestic and foreign has reached the mid-final exploitation stage.The old well recovery and the accident well processing gradually increased.Window sidetracking technology has been widely used as the main method to solve the problem. The conventional whipstock window cutting need decline whipstock and window cutting two steps, operation complex and cost expensive.The integral construction hydraulic pressure whipstock can complete two steps at one time, greatly shorten the construction period, save the construction cost. The integral construction hydraulic pressure whipstock has simple operation, sealing strong,short window cutting advantages etc .  The integral construction hydraulic pressure whipstock have two parts: whipstock and window cutting milling taper. 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 hig...

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 reli...
