CMC is an important cellulose ether, It is obtained by chemical modification of natural fiber and is a polyanion compound with good water-solubility, easily soluble in both cold and hot water.
CMC plays important role of reducing water loss and increasing viscosity in drilling fluid, cementing fluid and fracturing fluid, so as to protect the wall, carry drill cuttings, protect the drill bit, prevent mud loss and improve the drilling speed. Add directly or with glue solution to mud, add 0.1-0.3 to fresh water mud and 0.5-0.8 to salt water mud.
