Detailed Description
It is to guide the milling tool to form casing milling from the side window of special tools. I produced a self-proclaimed self-locking oblique hydraulic device.
First, the main parameters and technical performance
1, tool pressure: 35Mpa
2, total length: 3980
3, nominal diameter: 114
4 Nominal weight: 210KN
5, the piston forces: fluid pressure 210kg/cm2, the piston thrust 14.6t
6 for hole: 51 / 2 "casing
Second, the structure
Tool structure as shown, the tool is put on by the joint, put on the tube, inclined railways, the piston cone down cone, positioning slips outside the tube, just back the screw, cylinder, ball, adjusting the ring , rubber rings and other components.
Third, the principle
Under the whipstock into the pre-window position, through the drilling fluid pressure, push the piston down the spindle, spindle drive two pistons (six) slips on the radial movement stuck in the tube to achieve sealing seat. Slip between the mandrel and the piston axial thrust angle of 3 º, therefore, can achieve self-locking. Designed to prevent slips on the radial shape and prevent rotation of the tooth-shaped teeth down, which will enable the whipstock firmly stuck in the casing.

Casing by the whipstock packer rubber ring bottom to complete, the heart axis, the piston moves, the cone on the surface of softened rubber ring, casing packer to achieve the role.
V. Notes
SYDXQ114-30 hydraulic self-styled self-locking device to go down before the diagonal, relieved to go down before righting the body of the screw. When the whipstock into the next location scheduled to open the window to open the pump, when the slurry pressure reaches 210kg/cm2, the decentralization of drill slowly, when the weight indicator shows when the hanging weight reduction 10t, the whipstock seat seal success. Rotary drilling, the whipstock righting pole upside down unload opening newcomer drilling.
SYDXQ114-30 hydraulic self-styled self-locking whipstock during transport and may not go down before the collision deformation, to go down before righting the body of the screw should be relieved to go down.
