Bentonite undergoes great expansion when it is caught in water, so it possesses good characteristics of colloids, and it can add viscosity of suspension. When used for drilling mud, it can add lubrification of drilling too can clean rock cuttings produced in the course of drilling well. It can be extensively used for drilling construction of complex tectonic layer to avoid the hole trouble. The product is well-known for the good performance of good hydration, strong expansion with water, large exchange amount of positive ion and high mud production rate.
