Bentonite has the great expansibility under water and a good colloidal nature properties.It can increase the viscosity of suspension in the drilling mud when used.Increasing the lubrication of drilling and cleaning produces in the process of drilling cuttings, it is widely used to complex geological structure formation drilling construction, to prevent hole-accidents. The products are known for its good performance, strong water hydration expansion, big cation exchange capacity and high made pulp rate.
Applications:It is mainly used for petroleum geological drilling,power station,dam prevent penetration and city pipe jacking construction use, can lubricate drll pipe and drill,remove debris, forming a strong and impermeable in mud wall.
 
1).Used for oil and gas well drillig and civil-engineering,etc.
2).Used in the water mud,which has good lubricity and suspension property, also can be used to avoid rock-falling, collaps, and function in repairing the leakage.
3).Used as viscosifier and filtration control agent for water based Mud Systems.
4).Used for controlling borehole stability.
5).Bentonite drilling mud is widely used in construction, coating, fireproof, waterproof, heat preservation and special coating etc.
