The wireline drill pipe reamer has the following characteristics:
① The through cable reamer can stir up the coal slag deposited in the hole, improve the slag discharge capacity of the drill pipe, and also play the role of secondary cutting to reduce the coal slag and facilitate slag discharge;
② When the wireline drill pipe encounters hole collapse and hole collapse, the wireline reamer can ream the hole, and then discharge the cinder at the hole collapse to avoid sticking and burying the drill;
③ Ensure the normal transmission of signals in the drill pipe during drilling;
④ When a sharp turn occurs in the drilling hole, the hole with large curvature can be expanded to realize the smooth transition of the drilling track and avoid sharp turns;
⑤ According to different formation conditions, drill pipe and reamer can be combined at any distance to improve powder discharge efficiency.
