| description | The invention discloses a drifting device, and relates to the technical field of petroleum drilling engineering. The drifting device comprises a first milling column and a second milling column. The first milling column has a first cutting outer diameter. The second milling column is connected with the first milling column, the second cutting outer diameter of the second milling column is adjustable, and the first cutting outer diameter is within the adjusting range of the second cutting outer diameter. The drifting device can improve the drifting efficiency and reduce the drifting cost.
本发明公开了一种通井装置，涉及石油钻井工程技术领域。该通井装置包括第一铣柱和第二铣柱。第一铣柱具有第一切削外径。第二铣柱与第一铣柱连接，第二铣柱的第二切削外径可调节设置，第一切削外径落入第二切削外径的调节范围内。该通井装置能够提高通井效率，降低通井成本。 |
