China Professional Polyanionic Cellulose for Drilling

Our PAC-HV is used as drilling fluid additives.
PAC-HV is short for polyanionic cellulose of high viscosity. It is high molecular weight, high viscosity polymer for water-based drilling fluids, which can effectively reduces the filtration rate of many water-based oil and gas drilling fluids and may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environments.
Features:
1) Appearance: Free flowing off-white powder
2) Moisture content: 8% (max. )
3) Degree of substitution: 0.90 (min. )
4) pH of 1% solution: 6.0 - 8.5
5) Particle size: 95% (min. )
6) Pass through 40 meshes
Application:
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.
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.
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.
Restraining turbulence intensity and maintain the lowest pressure loss in circumfluence system Increasing slurry forming volume and reducing straining loss.
Stabilizing slurry foam.
PAC is not only an excellent slurry drilling fluid and well servicing fluid, but also a highly efficient pressing crack fluid.
