Anionic polyacrylamide is widely used in oil exploitation because of its good anionic properties and adsorption capacity. Anionic polyacrylamide can be combined with suspended solids or precipitates in petroleum to form complexes that improve oil-water separation efficiency and field recovery.
In oil production, anionic polyacrylamide is mainly used in the following aspects:
Viscosity reduction: During oil recovery, APAM combines with suspended solids in the water to form compounds that reduce the viscosity of the water, making oil recovery easier.
Enhanced oil recovery: Anionic polyacrylamide can be combined with the sediment to form aggregates that increase the density and size of the sediment, thereby increasing the sedimentation rate and making the oil easier to collect and extract, thus enhancing oil recovery.
Oil leakage prevention: In oil pipelines, APAM can be combined with oil to form polymer gel, which can prevent oil leakage and loss and reduce environmental pollution.
In conclusion, anionic polyacrylamide has a wide range of applications in oil production, which can improve oil recovery and oil-water separation efficiency, while also preventing environmental pollution. With the continuous development of petroleum industry and the increase of demand, APAM will be more widely used in oil exploitation.
