Petroleum grade product name: Petroleum drilling grade PAC product shape: White, yellowish powder package: paper plastic composite bag or three layers of Kraft paper packaging, each bag net content 20kg or 25kg storage: clean, dry, The function of polyanionic polyanion abundance (PAC) stored in ventilated place in drilling mud: high degree of substitution, good uniformity of substitution, high transparency, can control viscosity and reduce water loss, suitable for any water-based mud in fresh water or sea water, saturated salt water; The mud prepared with this product has good properties of reducing water loss, pseudo property and high temperature resistance, and the mud prepared with this product has rheological properties, and can disperse and expand clay and shale in high salt medium. Thus, the wellbore pollution is controlled, the soft soil structure is stabilized to prevent the wellbore collapse caused by the rise of water level, the accumulation of drilling solid in the mud is slowed down as the well drill passes through the rock surface, and the turbulence degree in the drilling pipe is restrained, So that the backflow system can keep the minimum pressure loss; so that the slurry can increase the amount of slurry production, reduce the amount of filtration; can stabilize the mud foam; PAC is a good mud drilling fluid and drilling repair fluid, but also high efficiency fracturing fluid.
