Drilling fluid Cellulose gum's Function:
1 . CMC-containing mud makes a well wall a thin, hard and low-permeability filter cake to reduce water loss.
2 . Adding CMC 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 . Slurry with CMC is seldom affected by the bacterium and requires no high PH value or corrosion resistant.
4 . The wall-cleaner treatment chemicals with CMC can resist the contamination of all kinds soluble salts.
5 . Slurry with CMC has excellent stability and will still reduce the filtration loss under 150℃ or above.
