Fracturing Fluid PAM High-Viscosity Enhanced Oil Recovery &
Mobility Control
Oil-displacement polyacrylamide (PAM) is a high-performance
oilfield chemical developed for enhanced recovery processes.
Appearing as a white crystalline powder, it dissolves readily in
water and offers excellent rheological behavior, with molecular
weights generally between 16 and 25 million. PAM provides
exceptional elastic viscosity and thickening power, ideal for water
flooding and polymer flooding techniques. It efficiently enhances
crude oil production by modifying the mobility ratio of injected
water and enlarging sweep coverage.

Performance and Applications
- High thickening ability: Long polymer chains form spatial networks in solution,
significantly raising viscosity and improving macroscopic sweep
efficiency.
- Good shear and thermal resistance: Retains molecular stability in high-temperature and high-salinity
environments, ensuring stable viscosity over time.
- Improved flow control: Helps adjust permeability distribution, guiding fluids into poorly
swept oil-bearing zones and increasing microscopic displacement
efficiency.
Key Advantages
Increases oil recovery rates with favorable economy and high
returns.
Compatible with formation and injection water, and works
effectively with surfactants and alkaline agents.
Adapts to challenging reservoir conditions with strong temperature
and salt tolerance.
