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 drilling?

For oil drilling, liquid or powder partially-hydrolyzed polyacrylamide is used as additives to water based drilling mud to provide a lubricating film and reduce friction at the drill bit, impart stability to shale and clay and increase viscosity [ 1, 22, 26 ].

Does polyamine water-based drilling fluid inhibit oil based drilling?

The results showed that the inhibition of polyamine water-based drilling fluid approached to or even surpassed that of oil-based drilling fluid. The system was also clean and lubricant. The EC50 of polyamine water-based drilling fluid was of 12 g/L which met the environmental requirement. Furthermore, the inhibition mechanism was briefly analysed.

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.

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.
