Abstract

Abstract:

In order to improve the viscosity-increasing performance of polyacrylamide solution in high temperature and high salt reservoir, the common method is to introduce association and salt-resistant monomer in the synthesis process. However, with the development of monomer synthesis technology, some temperature-sensitive copolymers appear. At present, there are few researches on the oil displacement performance of these polymers. For this reason, conventional binary copolymer AM-NaAA and temperature sensitive terpolymer AM-NaAA-RTM have been selected, and the basic physico-chemical properties, viscosity enhancement, temperature resistance and viscoelasticity of the two polymers have been compared. The results show that after the introduction of temperature sensitive monomers, when the temperature is below 60 ℃, with the rise of temperature, the viscosity of AM-NaAA-RTM decreases; but when the temperature is above 60 ℃, its viscosity increases with the rise of temperature; while at 85 ℃, the viscosity of AM-NaAA-RTM is more than double that of AM-NaAA, which is conducive to expanding swept volume of high temperature reservoirs. In addition, the viscoelasticity modulus of AM-NaAA-RTM is higher than that of AM-NaAA. Therefore, the oil flooding effect of temperature-sensitive polymer is better than that of conventional AM-NaAA polymer, which is expected to be applied in chemical flooding of high temperature and high salt reservoirs.

Key words: polymer flooding, temperature sensitive terpolymer, viscoelasticity, oil displacement efficiency, percolation and migration performance
