Main Usage：CMC&PAC can reduce water loss, and increase viscosity in drilling fluid, cementing fluid and fracturing fluid. They play the roles of protecting the wall of well, taking drilling trifles, protecting drilling bit. preventing mud loss and increasing drilling rate. Usage: add to mud directly or glue solution preparation. Addition: 0.1-0.3% in fresh water mud, 0.5-0.8% in salt water mud.
