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 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.

What is the use of polyacrylamide in oil extraction?

Oil extraction special polyacrylamide can be used as mud retarder, mud drag reducing agent, mud filter loss agent, mud plugging agent to reduce the difficulty of operation, to avoid accidents; in the completion and workover can be used as a filter, tackifier and clay stabilizer. 2.Polyacrylamide for oil flooding.

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.

Can modified polyacrylamide be used in drilling technology?
