Polyacrylamide is a kind of multifunctional oilfield chemical treatment agent, which is widely used in drilling, cementing, well completion, workover, fracturing, acidification, water injection, water shutoff profile control and tertiary oil recovery, especially in drilling, water shutoff profile control and tertiary oil recovery.Polyacrylamide solution has high viscosity, good thickening, flocculation and rheological regulation, and is used as oil displacement agent and drilling mud regulator in oil exploitation.In the middle and later period of oil exploitation, polymer flooding and asp flooding technology are mainly promoted in China to improve oil recovery.By injecting polyacrylamide solution, the ratio of oil to water velocity was improved and the content of crude oil in the produced product was increased.The addition of polyacrylamide to eor can increase the oil displacement capacity, avoid the breakdown of oil layer and improve the recovery rate of oil bed.China's petroleum industry is the largest user of polyacrylamide. The technological progress of polyacrylamide promotes the development of China's petroleum industry.
Efficient flocculation: Anionic polyacrylamide can effectively flocculate suspended particles in water, making them easier to separate from the water. This helps to improve the efficiency of filtration and sedimentation processes in water treatment.
Low dosage requirement: Anionic polyacrylamide is highly effective at low dosages, which makes it a cost-effective solution for water treatment.
Increase strength and settling speed of flocs. The flocs formed by polyacrylamide have high strength and good settling performance so that the solid-liquid separation speed and sludge dewatering facilitation can be improved effectively.
High stability: Anionic polyacrylamide is highly stable in a wide range of water conditions, including high pH and high salt concentrations. This means that it can be used in a variety of water treatment applications.
Reduced water turbidity: Under the premise of achieving the same water quality, the amount of flocculant can be greatly reduced by using pam as a coagulant aid in conjunction with other flocculants. As that, Anionic polyacrylamide can help to reduce water turbidity, which improves water clarity and makes it more visually appealing.
