CMC can be used to protect oil well as mud stabilizer and water retaining agent in oil drilling.
Package: Paper-plastic compound bag with PE liners,net weight 25KG. Storage: Sealed and stored in cool, dry conditions.
Sodium Carboxymethyl Cellulose (CMC) is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The functional properties of CMC depend on the degree of substitution of the cellulose structure , as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents.
CMC’s Features In Oil-Drilling Industry
1.High degree of substitution, good uniformity of substitution，high viscosity, low dosage, improve the performance of drilling mud.
2.Good resistance to humidity ,salt and alkali, suitable for fresh water, sea water and saturated brine slurry.
3.Stabilize soft soil structure and prevent collapse of wall of a well.
4.Suitable for a wide range of mud systems, unstable solid content mud system.
CMC For Fracturing Fluid:
2、Strong sand-carrying ability
3、Easy to be break
6、Better cross-linking performance
