Product Introduction
With carefully selected bentonite of high quality, then through the purification,
modification, processing we develop the bentonite for drilling mud, whose
quality meet international standards of OCMA and the United States API grade.
Product Usage
Bentonite has high expansion after meeting water and a good colloidal
nature, which can increase the viscosity of suspension in the drilling mud and
also can increase the lubrication of drilling, clean the debris during drilling,
as well as for the rig-freeing agent. So it is widely used in complex
geological formation drilling.
