| titleOfInvention | Polymer with selective water plugging function and preparation method and application thereof |
| abstract | The invention relates to the field of crude oil recovery, and discloses a polymer with a selective water plugging function, a preparation method and an application thereof, wherein the polymer comprises a structural unit A, a structural unit B and a structural unit C, the structural unit A is a structural unit with a structure shown in a formula (1), the structural unit B is a structural unit with a structure shown in a formula (2), and the structural unit C is at least one selected from the structural unit with a structure shown in a formula (3-1), the structural unit with a structure shown in a formula (3-2) and the structural unit with a structure shown in a formula (3-3). The polymer has a high-selectivity water plugging function, and a water plugging material formed by using the polymer can achieve the effect of high-selectivity water plugging without oil plugging. |
