Drilling bentonite

 

Drilling bentonite

Drilling bentonite

Drilling with sodium, calcium bentonite strict implementation of the Chinese National Standards: GB/T5005-2001 (eqv ISO 13500:1998), has a good suspension, thixotropy and filtration a small amount of mud performance is good, the preparation of convenient, easy to adjust the drilling fluid weight and other characteristics, is essential for deep and ocean drilling an ideal base material.
