Products Description
Polyanionic cellulose (PAC), a critical additive for drilling fluids, is a water-soluble polymeric compound derived through chemical modification of natural cellulose. Typically appearing as a white or light yellow powder, it exhibits excellent solubility in water, making it a fundamental component in various drilling fluid formulations.

Applacation
1.Filtration Loss Minimization
PAC effectively controls the fluid loss of drilling mud by forming a thin, compact filter cake on the wellbore surface. This mechanism restricts the invasion of drilling fluid into the formation, thereby preserving reservoir integrity and minimizing damage to oil and gas zones.
2.Viscosity Enhancement and Solids Suspension
By increasing the mud's viscosity, PAC improves the fluid's capacity to suspend and transport cuttings during drilling. This dual action ensures efficient removal of drilled solids to the surface, preventing settling and maintaining unobstructed circulation in the wellbore.
3.Wellbore Stability Promotion
PAC optimizes the rheological properties of drilling fluid, reducing turbulent flow and subsequent erosion of the wellbore walls. This stabilizing effect helps maintain borehole integrity, mitigating risks of collapse or instability caused by fluid-induced scouring during drilling operations.
