3.Product Useage
Bentonite has a big expansion after meets water, has a good colloidal nature,
can increase the viscosity of suspension in the drilling mud when used, can increase the lubrication of drilling, cleaning the debris during drilling, as well as for the rig-freeing agent. So which is widely used in complex geological formation drilling.
