APAM Oilfield Drilling Chemicals Anionic Polyacrylamide CAS 9003 05 8
Oil Field Drilling Chemicals Raw Materials Anionic Polyacrylamide
By means of adding a certain amount of polyacrylamide into the injected water and increaseits viscosity to improve the oil- water mobility ratio. The oil layer catches and absorbs the polymer molecules which lowers the permeability
of high and medium filter layer or swept layer, increase the seepage resistance of injected water, increase the water
absorption of low filter layer and low swept layer, enlarge the contact scale between injected water and oil surface and
the vertical water thickness on oil layer, therefor, enlarge the water volume to displace the remained oil in water
displacing and enhance the oil recovery ratio.
