CMC (carboxymethylcellulose ) for oil refining drilling fluid mud

 

 

 

Carboxy Methyl Cellulose CMC Sodium is one kind of poly anionic cellulose ether which has good solubility in both hot and cold water for oil drilling.

 

 

It has good water-loss controlling ability, 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 slurry’s other characteristics.

It can form high quality slurry cake which is strong and flexible.

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 the deep well.

It effectively controls the rheology of slurry, with good non-Newtonian fluid performance.
