Product DescriptionProducts DescriptionHigh viscosity PAC is a high-quality, high-molecular-weight, high-viscosity cellulose polymer. It is a linear polymer made of natural cellulose by alkalizing, etherification, repeated washing, drying and crushing, and has a good viscosity effect. The slurry fluid formulated with this product has good water loss reduction, inhibition, and high temperature resistance. It is widely used in oil drilling, especially brine wells and offshore oil drilling. The pulping amount is high, and the effect of reducing filtration loss is obvious. It is especially suitable for low-solids slurries and solids-free salt-cement slurries. The mud fluid formulated by PAC can inhibit the dispersion and expansion of clay and shale in high-salt media, so that the wellbore pollution can be controlled. The recommended increase is 0.2%-0.6%.
