Gerneral Overview
Drilling fluid grade PAC-LV is a low-viscosity high-purity polyanionic cellulose for high-density drilling fluids. Our pac powder features high-efficiency fluid loss control, especially suitable for deep and horizontal wells.
Core Product Advantages
1. High-efficiency Fluid Loss Control: High and uniformly distributed degree of substitution forms a thin, compact and tough filter cake, delivers low API fluid loss and reduces filtrate invasion into formations.
2. Minimal Impact on Rheology: Barely increases drilling fluid viscosity, enables precise control of equivalent circulating density, and adapts to high-density high-solid systems.
3. Excellent Temperature & Salt Resistance: Withstands temperature up to 150℃, excellent salt and calcium tolerance, adapts to all kinds of water-based drilling fluids such as fresh water, seawater and saturated brine.
4. Shale Hydration Inhibition: Inhibits shale hydration swelling, encapsulates drill cuttings, maintains wellbore stability and reduces downhole complications.
Technical Parameters
Drilling fluid grade polyanionic cellulose PAC-LV is a low-viscosity, high-purity anionic cellulose ether designed for high-density, high-solid water-based drilling fluid systems. It features high-efficiency fluid loss control with minimal impact on drilling fluid viscosity, enabling precise control of equivalent circulating density. With a high and uniformly distributed degree of substitution, it delivers excellent salt resistance, calcium resistance and temperature resistance, forms a thin, compact and tough filter cake to effectively reduce fluid loss, and inhibits shale hydration swelling while encapsulating drill cuttings. It has good compatibility with various drilling fluid additives, and is applicable to all kinds of water-based drilling fluids such as fresh water, seawater and saturated brine, especially suitable for working conditions with strict rheological control requirements like deep wells and horizontal wells.
