Guide to oil drilling applications

Polyanionic Cellulose referred to as PAC, is made from natural cellulose by chemical modification and the obtained water-soluble cellulose ether derivatives, is an important water-soluble cellulose ether, its sodium salt is usually applied. Polyanionic Cellulose has good heat stability and salt tolerance, anti-bacterial and strong. The product is prepared with a good drop of fluid mud water loss, inhibition,

highertemperature resistance. Widely used in oil drilling, especially offshore oil drilling wells and saltwater.

• Replace high, instead of uniformity, transparency, control viscosity and lower water loss； suitable for fresh water or sea water, saturated saltwater, any water-based mud;
• The product sluriy prepared with a good fluid loss, inhibition and high temperature properties；
• The produa is prepared using a slurry rheology, high-salt medium in inhibiting the dispersion of clay and shale and expansion, so that the wall of pollution under control;
• Stability of soft soil structure and prevent the water level rise caused by wall collapse；
• Wells drilled through the rock faces, cuttings in the mud slowed the accumulation of solids；
• Inhibition of drill pipe in the turbulence intensity, the return system to maintain the minimum pressure loss；
• The mud can increase the amountof mud to reduce fluid loss；
• Can stabilize the slurry bubble；PAC is an excellent repair and drilling mud drilling fluids, fracturing fluid is efficient.
