The oil and gas industry constantly seeks innovative solutions to maximize resource extraction and operational efficiency. NINGBO INNO PHARMCHEM CO.,LTD. underscores the indispensable role of polyacrylamide (PAM) in achieving these goals, particularly in enhanced oil recovery (EOR) and drilling fluid stabilization.

Polyacrylamide's Multifaceted Role in Oil & Gas

PAM's unique properties, such as its high viscosity, exceptional flocculation, and thickening capabilities, make it a versatile chemical agent in various oilfield operations. These include drilling, cementing, fracturing, and water plugging, but its most significant impact is felt in recovery and fluid management.

Enhanced Oil Recovery (EOR) Applications

In conventional waterflooding, a significant amount of oil often remains trapped in reservoirs. PAM-based polymers are crucial for improving oil recovery through techniques like Polymer Flooding. Here's how:

  • Viscosity Modification: PAM significantly increases the viscosity of the injected water. This improved viscosity allows the water to displace oil more effectively, pushing it towards production wells. Without this viscosity increase, the water would channel through the more permeable zones, leaving much of the oil behind.
  • Improved Sweep Efficiency: By controlling the mobility ratio between the injected fluid and the reservoir oil, PAM helps to ensure that the injected fluid sweeps through a larger portion of the reservoir, reducing residual oil saturation.
  • Reducing Water Breakthrough: PAM can also help to reduce premature water breakthrough into production wells, extending the period of effective oil production.

For EOR, the choice of polyacrylamide, often partially hydrolyzed polyacrylamide (HPAM), is critical, with molecular weight and ionic degree being key factors influencing performance in reservoir conditions.

Polyacrylamide in Drilling Fluids

In drilling operations, PAM serves multiple functions:

  • Drilling Mud Rheology Control: PAM acts as a viscosity modifier and fluid loss reducer in drilling muds. It helps maintain the desired rheological properties of the mud, ensuring efficient cuttings transport and wellbore stability.
  • Shale Inhibition: Certain types of PAM can act as shale inhibitors, preventing the swelling and dispersion of clay particles, which is crucial for maintaining wellbore integrity.
  • Friction Reduction: In hydraulic fracturing, PAM is used as a friction reducer, minimizing pressure losses during fluid injection and allowing for more efficient fracturing operations.
