Polyacrylamide for displacement of reservoir oil
Polyacrylamide for dis
The CA series of polyacrylamide for displacement of reservoir oil is a special product for tertiary oil recovery being designed and developed according to the oil-displacement principle and the features of oil deposit and through special molecules. The product has great resistance to temperature and salt, can increase viscosity, and has anti-shearing and other properties. It can effectively increase the viscosity of displacing fluid in oil deposit and the sweep efficiency, thus raising oil recovery.
