5 Tips to know How RC drilling rig works?

Picture
Air lift reverse circulation continuous sampling drilling is mainly used in the exploration of solid mineral resources, especially some special minerals and loose and broken formations. For example, the tertiary and quaternary conglomerate-type gold deposits or gold deposits that exist in structural fracture zones and alteration zones, it is difficult to obtain cores by ordinary core drilling methods, and it is easy to artificially cause mineral depletion or enrichment during drilling, which distorts geological data. . Kaolin and bauxite swell when exposed to water, and the rock core is susceptible to mud pollution. The use of air reverse circulation continuous sampling drilling can ensure accurate geological data and high efficiency. Air reverse circulation continuous sampling drilling can also be used in hydrological wells, engineering construction and other fields.
The circulating medium is first pumped into (flowed into) the drill bit at the bottom of the hole from the inner and outer pipe annulus of the double-wall drill pipe or the annular space of the drilling hole, and then returned to the surface from the central channel of the drill pipe (or the central channel of the inner pipe of the double-wall drill pipe) , to complete the well cleaning function.
​
  1.  The flushing medium has a small cross-section of the upper return channel, fast flow rate, strong carrying capacity for cuttings (including rock samples that can be used by the geological department), and the repeated breaking of the hole bottom is greatly reduced, and the well flushing effect is good;
  2. The flushing medium has little scouring on the hole wall, which is conducive to the stability of the drilling and reduces the accidents in the hole such as buried drilling and broken drill pipes;
  3. The cooling effect of the flushing medium on the drill bit is good, the drilling speed is fast, and the drill bit has a long service life;
  4. It can realize the drilling and sampling at the same time, and can know the drilling stratum at any time. The mining core has a high rate and strong representativeness, which is convenient for geological cataloging and true description of strata;
  5. When air is used as the circulating medium, water-saving drilling can be realized, and the construction advantages in arid and water-deficient areas are more prominent.
