Product Description

Sodium Carboxymethyl Cellulose

The Function of CMC OIL-DRILLING industry
1.CMC-containing mud makes a well wall a thin, hard and low-permeability filter cake to reduce water loss.
2.Adding CMC into slurry will endow the drill with low initial gel strength, making the slurry give off the gas inside and abandoning the
waste into the slurry pit.
3. Same as other suspending dispersion, the drill slurry has an existing period which will be stable and extended after adding CMC.
4.Slurry with CMC is seldom affected by the bacterium and requires no high PH value or corrosion resistant.
5.The wall-cleaner treatment chemicals with CMC can resist the contamination of all kinds of soluble salts.
6.Slurry with CMC has excellent stability and will still reduce the filtration loss under 150℃ or above.
Linguang 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.
Linguang CMC for fracturing fluid
1.Better gelation.
2.Strong sand-carrying ability.
3.Easy to be break.
4.Less residue.
5.Environmental friendly.
