CMC in oil drilling Characteristics
1. it has good water-loss controlling abiity,especially PAC is highly effective drop filter-loss agent.Even added at low quantity,it can control water loss at very high level.but does not affect slurrys other characteristics.
2. it can form high quality slurry cake which is strong and flexible.
3. it has good temperature resistance and certain rheology,so the viscosity in salt solution is the same as in water,which is specially suitable for sea misering and deep well.
4. it effectively controls the rheology of slurry,with good non-Newtonian fluid performance.

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.
