PAC
petroleum drilling grade polyanionic cellulose
Petrochemical product polyanionic cellulose (PAC) possesses excellent thickening, suspending, and stabilizing properties. In drilling fluids, PAC increases viscosity, improving fluidity and cuttings carrying capacity, effectively carrying drill cuttings back to the surface and preventing drill cuttings settling and stuck pipe accidents.
Petroleum-grade PAC
High-purity polyanionic cellulose (PAC) is a natural polymer chemical with strong suspending and stability properties, commonly used in the production of oilfield drilling mud, acid fracturing fluids, and fracturing fluids. One of its most prominent characteristics is its excellent dispersing properties, which effectively maintain the uniform distribution of solid particles in the liquid, preventing sedimentation and thus ensuring the stability of the fracturing fluid in complex environments.
Polyanionic cellulose
Polyanionic cellulose, or PAC for short, is a water-soluble anionic polymer compound produced from natural cellulose through chemical modification. This product is typically a white or off-white powder with excellent water solubility, thickening properties, film-forming properties, and salt resistance, making it one of the most widely used functional additives in current industrial applications.
Polyanionic cellulose powder is a polymer material with excellent heat stability, salt resistance, and antibacterial properties. Mud fluids formulated with it exhibit good water loss reduction, inhibition, and temperature resistance, and are widely used in oil drilling, especially in brine wells and offshore oil drilling.
