| titleOfInvention | Acrylamide copolymer and preparation method and application thereof |
| abstract | The invention relates to the field of oilfield chemicals, and discloses an acrylamide copolymer and a preparation method and application thereof. The acrylamide copolymer provided by the invention comprises a structural unit A, a structural unit B and a structural unit C, wherein the structural unit A has a structure shown in a formula (1), the structural unit B has a structure shown in a formula (2), the structural unit C has a structure shown in a formula (3), R is-OH, -NH 2 or-COOH; based on the total weight of the acrylamide copolymer, the content of the structural unit A is 85-95 wt%, the content of the structural unit B is 0.5-5 wt%, and the content of the structural unit C is 1-10 wt%; the acrylamide copolymer has higher viscosity under the conditions of high temperature and high mineralization degree, can lower the oil-water surface interfacial tension and has better emulsifying property |
