DESCRIPTION: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.
APPLICATION:1, PAC's application in drilling fluid
PAC used as inhibitor and filtration reducer is very good, and fluid mud made with PAC can inhibit
dispersion and expansion of clay and shale in high-salt media so that sidewall pollution of drill can be
controlled. Compared with CMC, PAC has better uniformity of response, with higher degree of
substitution, better transparency and excellent resistance to salt and heat. It can create high-volume
mud and cause low-volume loss, according to the test of OCMA.

3, PAC's application in fracturing fluid
Fracturing fluid made with PAC is resistant to 2% KCL solution (required when preparing fracturing fluid).
It features good dissolvability and easy to use. It can be prepared on engineering field and gum forming
is fast, with strong ability of carrying sand. If applied to the stratum of low osmotic pressure, its fracturing
effect is more remarkable.
