|Appearance:||Off-white Powder||Grade:||High Viscosity|
High viscosity CMC viscosifier for Drilling Fluid Additives
1 . CMC HV containing mud makes a well wall a thin, hard and low-permeability filter cake to reduce water loss.
2 . Adding CMC HV into slurry will endow the drill with low initial gel strength, making the slurry give off the gas inside and abandoning the waste into the slurry pit.
3 . Same as other suspending dispersion, the drill slurry has an existing period which will be stable and extended after adding CMC HV.
4 . Slurry with CMC HV is seldom affected by the bacterium and requires no high PH value or corrosion resistant.
5 . The wall-cleaner treatment chemicals with CMC HV can resist the contamination of all kinds soluble salts.
6 . Slurry with CMC HV has excellent stability and will still reduce the filtration loss under 150℃ or above.
Oil drilling grade CMC used in fracturing fluid, drilling fluid and well cementing fluid as fluid loss controller and tackifier. It can protect the shaft wall and prevent mud loss thus enhance recovery efficiency.
