A. The mud prepared by Lude Chemical®polyanionic cellulose (PAC) has rheological properties, which can simulate the dispersion and expansion of clay and shale in high-salt medium, so as to control the well wall pollution.
B. The slurry prepared by Lude Chemical® PAC has good characteristics of water loss reduction, preparation and high temperature resistance.
C. Lude Chemical® has high degree of substitution of PAC, good uniformity, high transparency, viscosity control and water loss reduction.
D. Lude Chemical® PAC is suitable for any water-based mud in fresh water or seawater, saturated brine.
E. Lude Chemical® PAC stabilizes soft soil structure to prevent shaft wall collapse caused by water level rise.
F. Lude Chemical®PAC slows down the accumulation of drilling solids in the mud when drilling through the rock surface.
G. Lude Chemical® PAC inhibits the turbulence in the drill pipe to keep the minimum pressure loss in the backflow system.
H. Lude Chemical® PAC can improve the slurry making capacity and reduce the filtration loss.
i. Lude Chemical®PAC can stabilize mud foam.
