PAC -HV/LV/R

1.  Description of productPAC(CARBOXY METHYL CELLULOSE-INTERMEDIATE)

Commercial Name: Polyanionic Cellulose

CAS NO: 9004-32-4

PAC is white or yellowish powder, which is non-toxic, odorless, and solvable in water, with stable resistance to heat, salt and bacteria. PAC is kind of high quality, low-viscosity cellulose polymer with low molecular weight. Mud fluid with this PAC can reduce fluid loss, with high inhibition and weather resistance. It is popularly applied to oil drilling especially brine well

4.Application

(1)  High 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 brine(2) Slurry 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 wall(3) Stabilizing 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 scar(4) Restraining turbulence intensity and maintain the lowest pressure loss in circumfluence system Increasing slurry forming volume and reducing straining loss.(5) Stabilizing slurry foam(6) PAC is not only an excellent slurry drilling fluid and well servicing fluid,but also a highly efficient pressing crack fluid.
