| titleOfInvention | Recyclable Integrated Window Side Drilling Tool |
| abstract | A recyclable integrated window side drilling tool, comprising a hollow milling cone, an inclined guide iron and a setting anchoring device connected in sequence, wherein the setting and anchoring device comprises a cylinder liner, and a cone arranged in the cylinder liner The utility model is characterized in that: the outer diameter of the cone is small in the upper part and large in the lower part, a ball seat with a setting edge is fixed at the inner lower end of the cylinder liner, and a setting steel plate is arranged in the ball seat ball, the lower end of the limit pipe is fixedly connected with the ball seat, and the upper part of the limit pipe is movably connected with the conical body through fine thread, so that the drilling fluid can push the conical body upward after entering the annular cavity in the cylinder liner under the conical body; The slips are divided into a plurality of longitudinal slips and radial slips, and the longitudinal slips and radial slips are alternately arranged and connected to the upper part of the outer periphery of the cone by shear screws evenly distributed along the circumferential direction. The tool has high working efficiency, can realize full recovery after sidetracking and completion, has a wide range of applications, can be reused after simple treatment after recovery, and has low use cost. |
