Oil Drilling Dedicated PAC(Polyanionic Cellulose)

Function of Poly Anionic Cellulose(PAC) in drilling fluid
High substitution degree, goodsubstitution evenness, high transparency, controllable viscosityand lower water loss Suitable for all kinds of water based slurryfresh water, sea water or saturated brine.
Slurry with this product has goodproperties of lower water loss, restraining, and high temperatureresistance Slurry with this product has rheological characteristicsthat it can restrain the separation and expansion of clay and shalein high salt medium, and consequently control the pollution of thewell wall.

Stabilizing the structure of softsoil and preventing well wall collapsing caused by water linerising Reducing solid drill bits piling up in slurry when drillgoes through scar.
Restraining turbulence intensity andmaintain the lowest pressure loss in circumfluence systemIncreasing slurry forming volume and reducing strainingloss.
