The excellent application of polyanionic cellulose PAC​

The excellent application of polyanionic cellulose PAC is embodied in:

a. High degree of substitution, good uniformity, high transparency, controlled viscosity and water loss reduction;

b. Any water-based mud suitable for fresh water or sea water, saturated salt water;

c. The mud prepared with this product has good properties of water loss reduction, fabrication and high temperature resistance;

d. The mud prepared with this product has rheological properties, which can simulate the dispersion and expansion of clay and shale in high-salt medium, so that the wellbore pollution can be controlled;

e. Stabilize the soft soil structure to prevent the well wall from collapsing due to rising water level;

f. When the well is drilled through the rock face, slow down the accumulation of drilling solids in the mud;

g. Suppress the turbulence in the drill pipe, so that the return system maintains a minimum pressure loss;

h. The mud can increase the amount of pulping and reduce the amount of filtration;

i. Can stabilize mud foam.
