Characteristics and Applications of NonIonic Polyacrylamide
For reservoirs with good homogeneity and high average permeability, polyacrylamide with medium molecular weight of 5x106-7x106 can be selected. High molecular weight 10x107 polyacrylamide can be selected for fractured reservoirs with low permeability of bedrock or reservoirs with large permeability changes.

Get PriceWhat is polyacrylamide used for?
Polyacrylamide is a versatile chemical treatment agent in oilfield. In oil extraction it could be used as a flooding agent, water shutoff regulator, drilling fluid regulator, fracturing fluid additives, especially in cementing, completion and workover. The oil industry is the largest area of polyacrylamide applications.
Why is polyacrylamide widely used in oilfields?
Fracturing process is an important stimulation measure for the development of dense layer in oilfield. Polyacrylamide is widely used because of its high viscosity, low friction resistance, good ability of sand suspension, small filtration loss, good viscosity stability, low residue, wide supply and easy preparation and low cost.
What is the use of polyacrylamide in tertiary oil recovery?
2.Polyacrylamide for oil flooding. In the tertiary oil recovery (EOR) with enhanced oil recovery, polyacrylamide can be used to adjust the flowability of injected water, increase the viscosity of the driving fluid, improve the efficiency of water flooding, reduce the permeability of water in the ground, To move forward.
What is the role of polyacrylamide for drilling mud additives?
1.Polyacrylamide for drilling mud additives. Drilling fluid in oil extraction works as drilling mud performance adjuster. PAM role is to adjust the rheology of drilling fluid, carrying cuttings, lubrication drill bit, favorable drilling.
What is polyacrylamide (PAM)?
Polyacrylamide (PAM) is not only a high-performance flocculants, but also because of the high viscosity of aqueous solution, but also a very good thickener. Due to its thickening, flocculation and regulation of rheological properties it can be used as a drilling fluid, fracturing fluid, and polymer flooding in the exploitation of oil extraction.
Is non ionic polyacrylamide a water soluble polymer?
Non-ionic polyacrylamide is a water-soluble high molecular polymer or polyelectrolyte. The characteristics of nonionic polyacrylamide PAM can be simply divided into the following three points: It has relatively good water solubility and can be completely dissolved even in cold water.
