Carboxy Methyl Cellulose (CMC) can be used as water-soluble gel for drilling fluids, and can form artesian well liquor.
1 Carboxy Methyl Cellulose (CMC) 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 Carboxy Methyl Cellulose (CMC) can form high quality slurry cake which is strong and flexible.
3 Carboxy Methyl Cellulose (CMC) 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.
