Sodium carboxymethyl cellulose (CMC)
1.CMC can be used as cementing fluid to prevent fluid from entering pores and fractures. It can be used as fracturing fluid to control the loss of liquid entering an oil well.
2.CMC can well control the rheological properties of slurry and has good non Newtonian fluid properties
3.CMC can make the quality of clay cake good, firm and tough.
Performance and usage: sodium carboxymethyl cellulose in the drilling fluid is mainly for viscous fluid loss agent, sodium carboxymethyl cellulose and a plurality of long molecular chains adsorbed on clay particles, cementation can increase the mud cake, can inhibit shale hydration expansion and consolidation of the wall effect. Aqueous solution of sodium carboxymethyl cellulose has many excellent properties and chemical stability, easy corrosion, physical safety is harmless, emulsification suspension effect and stability, good adhesion and anti salt ability of oil and organic solvents has good stability, therefore, is widely used in petroleum, food, textile, medicine papermaking and daily chemical industries.
