Polyanionic Cellulose PAC FOR Low Solid Phase Drilling Fluids
PAC (oil drilling grade) and are advantageous because of their:
small usage, high yield; good salt tolerance, anti-bacterial
property and convenient to use; the fluid loss reduction and the
viscosity improvement; flowing control and strong suspending
capability; environmental friendly, nontoxic, harmless and
odorless; and good liquidity, convenient to construction.
Polyanionic cellulose PAC are used in oil drilling fluids and
completion fluids. In drilling fluids, it works as viscosifier,
flowing controller and filtration reducer, with strong suspending
capability, high ability of carrying crumbs, and the function of
cleaning drilling crumbs, stabilizing of well wall, preventing the
mud from flowing away, protecting drilling bit and reducing the
thickness of mud cake, but while in the completion fluids, it
functions to control the fluid viscosity, suspend the heavy
objects, bring the filler and avoid the fluids loss. It also can
replace guar gum in fracturing fluids.
Polyanionic Cellulose PAC HV LV
Polyanionic Cellulose (PAC) (Polyanionic Cellulose) is a kind of nonionic cellulose ether
featured the properties of high purity, high DS, particularly high
viscosity or low viscosity. These products are demi-natural polymer
additive, thickening agent, filtrate reducer.
Polyanionic Cellulose (PAC) is an indispensable product for drilling mud making.
Polyanionic Cellulose (PAC) is high purity product; the water solution of this white powder is
transparent and viscid. As water-soluble polymer, it dissolves
immediately in cold/hot water and can be used as a thickening
agent, rheology controller, bond, stabilizer, colloid protector,
suspending agent, and filtrate reducer.
Polyanionic Cellulose (PAC) is a good drilling mud additive and also an important material for
confecting well liquid, a high mud volume product that featured
high acid-resistance and salt-resistance ability.
Polyanionic Cellulose (PAC) is a good filtrate reducer with the capacity of increasing
viscosity and anti-high temperature (150°C) in the freshwater,
seawater, or even saturated brine well-completion liquid.
Polyanionic Cellulose (PAC) is suitable for confecting the completion fluid with these 3 kinds
of water above.
