| titleOfInvention | Surface-active polymer and its preparation method and application as polymer oil-displacing agent |
| abstract | The invention relates to the field of oilfield chemistry, and discloses a surface active polymer, a preparation method thereof, and an application as a polymer oil-displacing agent. Wherein, the surface active polymer contains the structural unit A represented by the formula (1), the structural unit B represented by the formula (2), and the structural unit C represented by the formula (3); the weight of the surface active polymer is Benchmark, the content of structural unit A is 50-99% by weight, the content of structural unit B is 10-50% by weight, the content of structural unit C is 0.5-50% by weight, and the viscosity-average molecular weight of the surface active polymer is 12 million ‑18 million; the surface active polymer has a higher viscosity and sufficient ultra-low interfacial tension; |
