DEscriptION:Sodium Carboxymethyl Cellulose (CMC) is important cellulose ether and a good water-soluble polyanionic compound obtained from chemically modified natural fibers, soluble in cold water. It has unusual and extremely valuable comprehensive physical and chemical properties such as emulsifiablity, dispersion, solid dispersion, non-perishability, physiological harmlessness, etc., and is a kind of widely-used natural polymer derivatives.2. APPLICATION:CMC is used in oil drilling fluids and completion fluids. In drilling fluids, it works as viscosifier, flowing controller and filtration reducer, with strong suspending capability, high ability of carrying crumbs, and the function of cleaning drilling crumbs, stabilizing of well wall, preventing the mud from flowing away, protecting drilling bit and reducing the thickness of mud cake, but while in the completion fluids, it functions to control the fluid viscosity, suspend the heavy objects, bring the filler and avoid the fluids loss. It also can replace guar gum in fracturing fluids.3.
