The application of high-viscosity polyacrylamide in 7 aspects
1. Used as an oil displacement agent in the tertiary oil recovery methods to enhance oil recovery, using PAM as an oil displacement agent. The function of the polymer is to adjust the rheology of the injected water, increase the viscosity of the driving fluid, improve the efficiency of water flooding, reduce the permeability of the aqueous phase in the formation, and make the water and oil flow forward at a uniform speed. When high-viscosity polyacrylamide is flooded, surfactants and additives are first formulated into a microemulsion with ultra-low interfacial tension into the water injection well, then injected with polymer solution, and finally injected with water. The water flows forward in a plunger to displace residual oil dispersed in the pores and enhance oil recovery. PAM for three-pnezzarization generally contains 10% to 50%

Introduction of polyacrylamide
Polyacrylamide referred to as PAM, also known as the No. 3 coagulant, molecular formula CONH2 [CH2-ch]n, is a linear water-soluble polymer, molecular weight between 3 million and 18 million, the appearance of white powder or colorless viscous colloid, odorless, neutral, soluble in water, temperature more than 120 °C when easy to decompose. The high molecular weight produced by our factory, high-viscosity polyacrylamide can be beaten to 290 seconds in seconds, which is well received by users in the industry who need to thicken and viscous.
