Retardation and bridging effect of anionic polyacrylamide in

The adsorption and retardation effect on cement hydration further affect the setting time and early strength. In general, the setting time reflects the hydration process, From the results, the initial and final setting time firstly shows slightly shorten and subsequently sharply prolongs as the dosage of A-PAM increase.

Reduced adsorption of polyacrylamide鈥恇ased fracturing fluid

Polyacrylamide鈥恇ased fracturing fluid is commonly used in shale fracturing. Polyacrylamide (PAM) becomes adsorbed in the shale micro鈥恌ractures, decreasing the permeability of the reservoir. For improving the production of shale after being stimulated, the adsorption behavior and adsorption mechanism between the PAM and shale are studied.
