While-drilling well wall trimming tool

The invention provides a while-drilling well wall finishing tool which comprises a connecting pipe body, a well wall cutting component and a pushing component, the pushing component is installed in the connecting pipe body and moves downwards along the connecting pipe body during pressure building, and the pushing component is provided with a rotating guide part; the well wall cutting component comprises a cutting block, one end of the cutting block is hinged to the connecting pipe body, the other end of the cutting block is arranged on the rotating guide part in an erected mode, and the cutting block rotates and expands outwards along the rotating guide part when the pushing component moves downwards. The two-stage variable-diameter micro-reaming device has the advantages that two-stage variable-diameter micro-reaming operation is achieved, the well wall is effectively and smoothly trimmed, and the drifting operation time is shortened. 本发明提供一种随钻井壁修整工具，包括连接管体、井壁切削部件和推动部件，其中，所述推动部件安装于所述连接管体内，并在憋压时沿连接管体下移，所述推动部
