GK ---- The opponent to the ravelly ground
With high
speed, durability and toughness, when drilling the homogeneous
formation, the lip of GK can scrape the stratum, and the spherical
prominence can control the footage. When meeting with the ravelly
ground, the spherical prominence can break the rock into gravels and
squeeze them into the gaps, thereby reducing the vibration of drill and
speeding up the drilling. In conclusion, GK can not only apply to the
homogeneous formation, but also the ravelly ground, that’s why we can
call it “The opponent to the ravelly ground”.
