| 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 shown in formula (1), said structural unit B is a structural unit having a structure shown in formula (2), and said structural unit C is selected from those having a structure shown in formula (3-1) At least one of a structural unit, a structural unit having a structure shown in formula (3-2) and a structural unit having a structure shown in formula (3-3). The polymer of the present invention has a highly selective water shutoff function, and the water shutoff material formed by using the polymer can achieve the effect of highly selective water shutoff but not oil shutoff. |
