| titleOfInvention | Milling cone tool for windowing and sidetracking of casing for yield-increasing transformation of circumferential multi-branch pore canals |
| abstract | The utility model discloses a milling cone tool for windowing and sidetracking a sleeve for yield-increasing transformation of a circumferential multi-branch pore passage, which comprises a base body, wherein spiral cutter blades are uniformly distributed on the outer side of the lower part of the base body, milling blades are uniformly distributed on the outer side of the middle part of the base body, grinding teeth are uniformly distributed on the outer side of the upper part of the base body, the top end of a fixing plate is connected with a casing through a bolt, a rotary table is fixedly connected with the driving end of the bottom end of a motor, and clamping grooves are uniformly distributed in the rotary table and matched with clamping strips. According to the utility model, through the integrated design of window opening, window milling and window repairing, sidetracking time is effectively saved, work efficiency is improved, the purpose of stable transmission is achieved through the mutual matching of the clamping strip and the clamping groove, the fixing plate is connected with the casing through the bolt, the installation is simple, the later-stage disassembly and maintenance of the milling cone tool are facilitated, the protecting ring can protect the bolt and the joint of the workpiece from soil erosion, the service life of the device is prolonged, and the device is worth of being widely popularized. |
