Description
Shale inhibitor polyanionic cellulose PAC-R is a high quality, high molecular weight, high viscosity cellulose polymer,it has good heat stability and salt resistance, strong antibacterial.The mud fluid prepared by PAC-R has good water loss, inhibition and high temperature resistance which can widely used in oil drilling, especially brine water wells and offshore oil drilling.
Suitable for any mud from pure water to saturated brine water.
Shale inhibitor polyanionic cellulose PAC-R has obvious filtration reduction effect,especially suitable for low solid phase mud and solid-free brine mud.The slurry fluid inhibits the dispersion and expansion of clay and shale in a highly saline medium, thereby controlling wall contamination.
Shale inhibitor polyanionic cellulose PAC-R is excellent mud as drilling fluid,workover fluid and also fracturing fluids.
Application
· Control filtration rates with minimal increase in rheology.
· Aids in the formation of a tough, thin filter cake to minimize the potential for differential sticking.
· With low dosage and high pulping rate.
· With minimal increase in rheology .
· Easily soluble in water.
· No fermenting and no biocide needed.
· Environmentally compatible, non-toxic and odorless.
· Inhibit hydratable to swelling shales.
Advantages
· Acid, alkali and salt resistance , can be used in all kinds of polar harsh environment.
· Good compatibility: soluble with other cellulose ethers, water-soluble gum, softener, resin and so on;
· Good solubility: simple stirring equipment can be quickly dissolved in cold and hot water;
· Good stability :Aqueous solution has light stability and longer shelf life;
· Very low usage: In the same use environment, its dosage is only equivalent to carboxymethyl cellulose (CMC) 30%-60%;
·Is not harmful to physiology, and the production process is green.
· Can be used in deep and high-temperature downhole operations.
