BENTONITE

Bentonite swells greatly when it meets water. It owns excellent colloid nature and can increase the viscosity of suspend fluid. While it is applied in drilling mud, it can improve the lubricating property of drilling tools and can clean the rock clinker. It is widely applied in drilling constructions at stratums with complicated structures to avoid accident.

Advantages of Bentonite Powder Drilling Mud Additive

As bentonite contains of 60-80% montmorillonite it provides special properties such as swelling and adsorption.The triple-layer silicate can absorb an exceptional quantity of water and expands by a multiple of the original size. The inner surface of a gram of bentonite is 400–600 m² normal clay only has 2 m². The swelling and viscosity behavior of bentonite in the presence of water as well as its particularly high inner surface open numerous application options for the mineral.

  • Bentonite extracts the drill cutting from around the bit which is then floated to the surface.
  • Bentonite seals the drill hole against seepage and prevents wall cavities and leakages.
  • Bentonite (Drilling mud) served to cool and lubricate the drill bit.
  • Bentonite form slurry with leakages that is pumped through drill stem and out through drill bit. 

Application of Bentonite Powder Drilling Mud

  • Drilling mud (gel) is crucial in the extraction of drill cutting during the drilling processes.
  • Drilling mud (gel) is a major component in well drilling process.
  • Another conventional use of bentonite is as a mud constituent for oil and water well drilling. Its roles are mainly to seal the borehole walls, to remove drill cuttings and to lubricate the cutting head.
