Integral Construction Hydraulic Pressure Whipstock
The exploitation of many oil fields has reached the mid-final stage. The old wells recovery and the accident wells increased gradually. The technology of window cutting sidetracking,as a main method to solve these problems, has received wide application.
The conventional whipstock fenestration needs two operations, whip stock and fenestration, which are complex and expensive. However, integral type whip stock realizes the two operations at a time, so it shortens the construction period and save the cost.
The integral construction hydraulic pressure whipstock made by our company has lots of advantages, such as easy operating, firm sealing and short window cutting time and so on.
The integral construction hydraulic pressure whipstock is divided into two parts including whipstock and window cutting milling cone.
1. Whipstock
Whipstock adopts hydraulic pressure sealing which is firm and easy to operate. The inclined plane is arc-like and receives super hardening treatment. The milling cone coincides highly with the inclined plane when window cutting. Due to easy controlled drilling pressure, the can drill and dance drill phenomenon is decreasing. Tool internal adapts safe and reliable pressure transmitting mechanism. The more perfect self-locking mechanism adopts axial and circumferential methods which greatly improve the tool reliability.
2. Window Cutting Milling Cone
Window cutting milling cone and whipstock cooperate to complete window cutting work in pipe. Considering designing, tool shape, cutting edge angle and alloy block selection are optimized. The window cutting milling cone assembles window cutting and fixing as integrality. This design improves the construction speed and shortens the period.
