Description
Anionic polymer, readily water-soluble. Inhibits hydration-swelling and dispersion of water-sensitive shale and clay to stabilize wellbore. Powerful inhibition of formation mud-making; also delivers fluid-loss control and rheology-modification to protect hydrocarbon zones.
Appearance
White or pale-yellow free-flowing powder.
Main Advantages
- Strong inhibition of clay & cuttings hydration-dispersion.
- Good thermal-salt tolerance and moderate fluid-loss control.
- Effective for formation mud-control and wellbore stabilization.
- Compatible with anionic / amphoteric additives.
- Suitable for fresh-water, salt-water, saturated-salt-water water-based drilling fluids of various densities.

Application
Prepare dilute polymer solution before adding to avoid agglomeration. Recommended dosage 0.15%–0.5%. Do not pour dry powder directly into mud pit: add powder slowly under vigorous stirring until fully dissolved.
Dosage Guidance
0.15%–0.5%.
Packaging & Storage
3-in-1 composite bags with PE liner, net 25 kg/bag. Cool dry ventilated storage. Avoid skin-eye contact; rinse with plenty of water. Keep away from fire.
