Hydrolyzed polyacryloitrile Ammonium Salt (NH4-HPAN)
This product is light yellow or brown powder, easily soluble in water.
This product has high filtration loss reduction ability in fresh water or salt water, the apparent viscosity can be controlled at a lower level, while reducing filtration loss can also significantly reduce the viscosity of drilling fluid, improve the rheology of mud. In addition, this product also has a significant effect on inhibiting shale expansion, which can effectively protect the wall of the easily collapsed well.
