Bentonite for drilling

    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.

Salt resistance bentoniteBridge

Application of Manufacturing Techniques of Slurry by Seawater ,Anti- salt bentonite from environmental geographical restrictions to get water,Unaffected by severe weather, can be used at any time. It has a fast speed of dissolving, good hydration, high mud-making rate, very thin, strong stability, high abaility of solid wall, low drill swing resistance, high drilling rate etc. Especially encountered sediment layers and salt in the construction, can prevent to collapse with strong inhibition,also prevent to expand of the holes, reduce to meet resistance in the drilling process, be not to the end or sticking, etc.
