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.
