Anionic Polyacrylamide
  Anionic Polyacrylamide for EOR(Enhance Oil Recovery)
˜Application
Short for PAM, as oil displacement agent in oil recovery, will increase injected water viscosity; improve oil-water mobility ratio; expand swept volume; enhance oil recovery ratio. Can be used alone for polymer flooding, and can also be combined with Alkali, surfactants for SP or ASP flooding, is main measure to further control & reduce cost and enhance oil recovery after water flooding period.
˜Characteristic
Based on oil displacement mechanism and reservoir conditions, PAM for EOR is developed and selected through special molecular design. Products has remarkable viscosity increasing effect, anti- salt & high temperature, good shear cut resistance, excellent thermal stability, Increase displacement fluid viscosity effectively, Improve the sweep efficiency , expand swept volume, enhance oil recovery ratio finally.
