polyanionic cellulose

Function of Poly Anionic Cellulose (PAC) in drilling fluid,

Petroleum appropriation type PAC

Both petroleum appropriation type PAC and CMC meet API13I and API13A standards

Function of Poly Anionic Cellulose (PAC) in drilling fluidHigh substitution degree,good substitution evenness,high transparency,controllable viscosity and lower water loss Suitable for all kinds of water based slurry fresh water,sea water or saturated brineSlurry with this product has good properties of lower water loss,restraining,and high temperature resistance Slurry with this product has rheological characteristics that it can restrain the separation and expansion of clay and shale in high salt medium,and consequently control the pollution of the well wallStabilizing the structure of soft soil and preventing well wall collapsing caused by water line rising Reducing solid drill bits piling up in slurry when drill goes through scarRestraining turbulence intensity and maintain the lowest pressure loss in circumfluence system Increasing slurry forming volume and reducing straining lossStabilizing slurry foamPAC is not only an excellent slurry drilling fluid and well servicing fluid,but also a highly efficient pressing crack fluid.
