How to speed up the penetration rate of roller drill bit core barrel

When using roller drill bit core barrel drilling, the perfect vibration is a small high-frequency vibration.

Not only does not damage the roller drill bit, but also the longitudinal impact it produces can speed up the penetration rate.

In contrast:

1. No vibration
   Most of the reasons are too much sediment and slow penetration. The treatment method is to take out the roller bit core barrel and clean the roller drill bit with a high-pressure water gun;
   Another is that the alloy teeth of the roller drill bit are worn out, take them out and replace them with new roller drill bits.
2. There is obvious large periodic vibration
   Check whether there is a biased hole, whether there is inclined rock or there is rock on one side and no rock on the other side;
   The welding position of the roller drill bit is not very accurate, find the problematic roller drill bit and correct the welding.
