First, the tool profile
Mainly by the connector, into the rod, guide inclined body, shell, anti-slip slips, anti-slip off, under the plug wire, righting plate and other components. The anchor assembly hangs the ramp in the casing and mills the casing window on the inside wall of the casing along the ramp surface through the window milling cone.
Second, the working principle
Connected to the drill down to the design depth, adjusted to a predetermined orientation, open the pump pressure to 15-20MPa, push the upper and lower piston push up and down the slip on the inner wall of the tube, a special locking device to lock the piston, positive Turn the drill string upside down into the tool. Then, into the window with the milling cone to complete the window operation.

Fourth, technical characteristics
1. Hydraulic seat hanging slips, simple and reliable operation, suspension force, accurate card position;
2. Two sets of slip design, to prevent the axial and circumferential movement of the inclined device;
3. Inverted hand throwing release tool, drilling speed is not limited, the operation is simple and reliable;
4. Oblique surface hardening treatment, good wear resistance.
