Polyanionic Cellulose

We are offering polyanionic cellulosic (pac) for oil drilling.
Pac can be used as water-soluble gel for drilling fluids, and can from artesian well liquor.
1) it has good water-loss controlling ability; especially pac is highly effective drop filter-loss agent. Even added at low quantity, it can control water loss at very high level, but does not affect slurry�s other characteristics.
2) it can form high quality slurry cake which is strong and flexible.
3) it has good temperature resistance and superior anti-salt character. Under certain salt density, it can remain good water-loss capability and certain rheology, so the viscosity in salt solution is the same as in water, which is specially suitable for sea misering and deep well.
4) it effectively controls the rheology of slurry, with good non-newtonian fluid performance.
