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.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
