Solid Glass Beads For Oil Well Drilling
Glass Beads has good chemical stability,perfect regularity,clean surface, transparent, solid soda lime glass material made, Good fluidity, no air bubbles, less consumption,the Glass Beads are chemically inert and do not effect the chemical characteristics of the mud system, so it can be used as drilling material in the oil field.
