Application of Polyacrylamide in Petroleum Drilling

Polyacrylamide (PAM) is not only an efficient flocculant, but also an excellent thickener due to its high aqueous solution viscosity. Polyacrylamide (PAM) has thickening properties, flocculation properties and rheological properties, and can be used as additives for various purposes in petroleum production, such as drilling fluids, fracturing fluids, and polymer flooding for enhanced oil recovery (EOR) .
When polyacrylamide (PAM) is used as a drilling fluid additive, polyacrylamide (PAM) adsorbs on the surface of metal or clay particles to form a liquid film to lubricate the drill bit and drilling tool, reduce the friction coefficient of mud cake, and reduce hole bottom accidents. The suspending ability of polyacrylamide (PAM) in drilling fluid is of great significance in industries such as oil and gas production.
Polyacrylamide (PAM) is a kind of high molecular chain polymer, which can wrap the debris, making it difficult to disperse the debris in the hydraulic drilling fluid. The waste can be separated from the sludge through a vibrating screen to remove the harmful solid phase in the sludge. Polyacrylamide also has a good anti-friction effect, which can significantly reduce the friction between the rotating drill pipe and the borehole wall, as well as the friction between solid particles and solid particles in the mud, thereby reducing drilling torque and borehole pressure.

Shandong Welldone, as China top 10 polyacrylamide manufacturer, could offer suitable partially-hydrolyzed polyacrylamide (PHPA) that you need.
