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.

Why is nonionic polyacrylamide a high molecular polymer?

Nonionic polyacrylamide is a high molecular polymer. Its molecular chain contains a certain amount of polar genes, which can adsorb suspended solid particles in water. Polyacrylamide can accelerate the sedimentation of particles in the suspension,polyanionic cellulose polymeraccelerate the clarification of the solution and promote the filtration.

What are the uses of non ionic polyacrylamide?

The non-ionic polyacrylamide is dissolved into 0.3% concentration and added with crosslinking agent, which can play a role in sand control and sand fixation. 3. Oil exploitation. Polyacrylamide is used in mud additives, stabilizers and sedimentation flocculation to improve the rheological properties of mud. 3.

Is polyacrylamide cationic or nonionic?

Polyacrylamide is mainly cationic, anionic and non-ionic. Among these types, the application range of nonionic polyacrylamide is limited. The production volume and model of the manufacturer are also relatively small. Home Products Clients Quality Infrastructure Manufacturing Certificate Contact Home News Latest News

Is nonionic polyacrylamide a good flocculant in water treatment industry?

The nonionic polyacrylamide is a good flocculant in water treatment. It can adsorb the solid particles in the water, so that the particles in the water can agglomerate into a relatively large floc. There are many applications of non-ionic flocculants in water treatment industry. Nonionic polyacrylamide is a high molecular polymer.
