Polyacrylamide in the oil is how to use it? Polyacrylamide PAM for a wide range of uses, superior performance, it is foreseeable in the near future it will show more important areas of application prospects. In recent years, researchers have made great progress in the synthesis and application of AmPAM. However, there are still many mechanisms and performance problems to be further studied. In the field of oil recovery, China has now entered the second or third oil recovery stage, Amphoteric polyacrylamides with temperature resistance, salt resistance and shear resistance will exert their unique properties for increasing the oil recovery rate. Studies have shown that amphoteric polyacrylamides with "anti-polyelectrolyte effect" are ideal for high temperature, high salt reservoir polymer flooding agents and are known as second generation polymers that increase oil recovery. The amphoteric polyacrylamide was used as oil displacement test. The results showed that the amphoteric polymer recovery was improved by 4.3% and the final recovery rate was 80% under the same conditions than the partially hydrolyzed polyacrylamide. In the field of oilfields, polyacrylamide can also be used as a thickener drilling fluid, mud viscosity reducer, fluid loss control, plugging water control profile. In addition, amphoteric polyacrylamides are also used in mineral screening, superabsorbent resins, leather retanning agents, surfactants and soil amendments.
