bentonite for drilling wells

high purity;high dispersion fineness good distensibility of water;large ion change; work well in acidic and basic condition

After the purification,modification,processing.developed with the bentonite for drilling mud,which quality meet European standards of OCMA and the United states API grade.

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.
