| titleOfInvention | Polymer with selective water blocking function and its preparation method and application |
| abstract | The invention relates to the field of crude oil recovery, and discloses a polymer with selective water shutoff function and its preparation method and application. The polymer contains structural unit A, structural unit B and structural unit C, wherein the structural unit A is a structural unit having a structure represented by formula (1), said structural unit B is a structural unit having a structure represented by formula (2), and said structural unit C is a structural unit having a structure represented by formula (3). The polymer provided by the present invention has a highly selective water blocking function, and the water blocking material formed by using the polymer can obtain the effect of highly selective water blocking without oil blocking, and the polymer of the present invention has excellent temperature resistance Salt performance and expansibility, which can reduce the permeability of water phase and increase the plugging effect of water phase. |
