Carboxymethyl Cellulose Sodium Oil Well Drilling grade CMC

Quick Detail:

The Carboxymethyl Cellulose (CMC) is produced by chemical modification of cellulose, the most abundant polymer in nature and a major component of wood and cotton.CMC acts as thickener, rheology modifier, water retention aid, binder, dispersant, floating aid, etc. This wide range of properties makes CMC virtually useful everywhere water is involved in a process and more typically in ceramics, coatings, detergency, drilling fluids, food, mining, paper, textiles (sizing and printing)

Description:

Oil Well Drilling grade Product features:

1, high degree of substitution, good uniformity of substitution .

2, high transparency, viscosity and water loss can be controlled .

3, suitable for fresh water, sea water, saturated brine slurry .

4, stabilize soft soil structure, prevent collapse of wall of a well .

5, can improve mud-making volum, reduce filteration loss .

6, has excellent performance in drilling of oil .

Applications:

CMC and PAC can reduce water loss, and increase viscosity

in drilling fluid, cementing fluid and fracturing fluid. They play the roles of protecting the wall of well, taking drilling trifles, protecting drilling bit, preventing mud loss and increasing drilling rate. Usage: add to mud directly or glue solution preparation.

Addition: 0.1-0.3% in fresh water mud; 0.5-0.8% in salt water mud
