The oil and gas industry continuously seeks innovative solutions to maximize resource extraction and optimize operational efficiency. Polyacrylamide (PAM), a highly versatile water-soluble polymer, has emerged as a critical chemical in several key applications within this sector, particularly in Enhanced Oil Recovery (EOR) and as a vital additive in drilling fluids. As a prominent Polyacrylamide manufacturer and supplier in China, we provide specialized PAM grades designed to meet the demanding conditions of the oilfield.

Polyacrylamide in Enhanced Oil Recovery (EOR):

In mature oilfields, traditional extraction methods often leave a significant portion of recoverable oil trapped within the reservoir rock. EOR techniques, such as polymer flooding, are employed to increase oil recovery. PAM, particularly high molecular weight anionic PAM (HPAM), is a cornerstone of polymer flooding due to its ability to:

  • Increase Injection Water Viscosity: When injected into the reservoir, PAM significantly increases the viscosity of the drive water. This improved viscosity helps to sweep more oil towards production wells by reducing viscous fingering and improving sweep efficiency, especially in reservoirs with high permeability variations.
  • Reduce Fluid Mobility Ratio: By making the injected water more viscous, PAM effectively lowers the mobility ratio between the injected fluid and the reservoir oil, leading to more uniform displacement and higher oil recovery rates.
  • Improve Sweep Efficiency: PAM can selectively plug high-permeability zones (thief zones) that would otherwise bypass significant oil reserves, ensuring a more complete sweep of the reservoir.

The selection of PAM for EOR is critical, requiring specific properties such as high molecular weight, appropriate degree of hydrolysis, and tolerance to reservoir conditions like high temperature, salinity, and shear stress. As a dedicated PAM supplier, we offer grades engineered for these challenging environments.

Polyacrylamide in Drilling Fluids:

Drilling fluids, or muds, are essential for successful oil and gas well drilling. They perform multiple functions, including:

  • Lubrication and Cooling: PAM derivatives act as lubricants and coolants for the drill bit and borehole walls.
  • Viscosity Control: PAM can be used as a viscosifier, helping to suspend drill cuttings and carry them to the surface.
  • Shale Inhibition: Certain PAM formulations, particularly cationic or amphoteric types, can help stabilize shale formations by preventing hydration and swelling of clay particles. This reduces borehole instability and drilling complications.
  • Fluid Loss Control: PAM can help reduce the filtration of drilling fluid into permeable rock formations, maintaining wellbore integrity and preventing formation damage.

The specific requirements for PAM in drilling fluids depend on the drilling depth, formation types, and the type of drilling fluid system (e.g., water-based muds). Properties like salt tolerance, temperature stability, and shear stability are paramount.
