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, wherein the acrylamide copolymer comprises a structural unit A, a structural unit B and a structural unit C, wherein the structural unit A is a structural unit shown in a formula (I), the structural unit B is a structural unit shown in a formula (II), and the structural unit C is a structural unit shown in a formula (III); and the content of the structural unit A is 70-90 wt%, the content of the structural unit B is 8-28 wt%, and the content of the structural unit C is 0.1-5 wt% based on the total weight of the acrylamide copolymer. The acrylamide copolymer can be used as a thermal thickener for tertiary oil recovery of high-temperature and high-salinity oil reservoirs. |
