Drilling Mud Bentonite BK®-181
Bentonite swells greatly when it meets water.It owns excellent colloid nature amd can increase the viscosity of suspend fluid. While it is applied in drilling mud,it can improve the lubricating property of drilling tools and can clean the rock clinker. It is widely applied in drilling constructions at stratums with complicated structures to avoid accident.
