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 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 based on the total weight of the acrylamide copolymer, the content of the structural unit A is 43.5-98 wt%, the content of the structural unit B is 0.6-39 wt%, and the content of the structural unit C is 0.6-39 wt%. The acrylamide copolymer has good water solubility and thermal thickening effect, is suitable for being used as a thermal thickener for tertiary oil recovery of high-temperature and high-salinity oil reservoirs, |
