Introduction of sodium based drilling bentonite

  Sodium based bentonite is produced according to the Chinese National Standards: GB/T5005-2001 (eqv ISO 13500:1998). This material is as a mud constituent for oil- and water- well drilling. Its role is mainly to seal the borehole walls, to remove drill cuttings and to lubricate the cutting head. The special higher mud yield results in using less quantity of Bentonite for the same standard mud. This results in lesser requirement of Bentonite.

 

Production information for the sodium based drilling bentonite
We choose the high quality bentonite ore. After the purification, modification and processing, then thesodium based drilling bentonite forms. We can produce thesodium based drilling bentonite well meeting European standards of OCMA grade and the United States standards of API grade.
