Under the normal condition of clean borehole at the bottom of the well, intermittent bouncing and jumping will occur during pressurized drilling. The load of the rotary table is light and sometimes heavy, the torque meter shows high and low, and the bouncing and jumping are irregular. The rotary table is generally bouncing and strong, but it is not reversed. The bit is raised from the bottom of the well and rotated normally.
