Maximizing oil extraction from mature fields is a persistent challenge in the petroleum industry, driving the need for advanced Enhanced Oil Recovery (EOR) techniques. Among the chemical EOR methods, polymer flooding using polyacrylamide (PAM) stands out as a highly effective and widely adopted strategy. As a leading manufacturer and supplier of polyacrylamide in China, we provide high-performance PAM grades specifically designed to boost oil recovery rates.

The Mechanism of Polymer Flooding in EOR

Polymer flooding involves injecting water-based polymer solutions into oil reservoirs to improve the sweep efficiency of the injected water. The primary function of polyacrylamide in this context is to increase the viscosity of the injected water. This increased viscosity helps to:

• Improve Water-Oil Mobility Ratio: High-viscosity polymer solutions reduce the mobility of the injected water, preventing it from bypassing the oil trapped in the reservoir and “fingering” through it. This ensures that the injected water pushes more oil towards the production wells.
• Reduce Reservoir Permeability Mobility Ratio: By altering the viscosity of the displacing fluid, PAM helps to maintain a more stable displacement front, leading to better volumetric sweep efficiency and consequently, higher oil recovery factors.
• Enhance Sweep Efficiency: PAM's ability to increase water viscosity leads to a more uniform displacement of oil from porous media, reaching previously unswept zones within the reservoir.

Key Polyacrylamide Properties for EOR

Successful polymer flooding requires specific properties from the polyacrylamide used. Our manufacturing expertise ensures our PAM products meet these critical demands:

• High Molecular Weight: Our EOR-grade polyacrylamides are characterized by high molecular weights, which are essential for imparting the necessary viscosity to the injection water.
• Shear Stability: PAM formulations are designed to withstand the shear forces encountered during injection and flow through porous media without significant degradation, ensuring sustained viscosity for effective displacement.
• Thermal and Salinity Tolerance: Depending on reservoir conditions, specific PAM types are available that offer resistance to high temperatures and varying salinity levels, crucial for performance in diverse geological environments.
• Purity and Consistency: As a reputable manufacturer, we guarantee high purity and consistent product quality, which are vital for predictable reservoir performance and economic viability of EOR projects.
