Abstract: Through actual drilling tests in the 50 meters wells, the SH25H hydraulic pneumatic impact drill was trial manufactured with the pneumatic DTH and local inverse circulation rotary drilling technology, and continuous footage was ensured by retractable drill pipe. The multi-techniques drilling technique is developed with high drilling efficiency and high quality of borehole.
