| titleOfInvention | A kind of polymer and its preparation method and application with surface active function |
| abstract | The invention discloses a kind of polymer and its preparation method and application with surface active function.The polymer with surface active function contains structural unit A, structural unit B and structural unit C, structural unit A is structural unit shown in formula (1), structural unit B is structural unit shown in formula (2), structural unit C is structural unit shown in formula (3), on the basis of the weight of the polymer with surface active function, the content of structural unit A is 5-60 weight %, the content of structural unit B is 30-90 weight %, and the content of structural unit C is 0.1-10 weight %；The viscosity average molecular weigh of the polymer is 15,000,000-2,800 ten thousand.Polymer provided by the invention has the advantages that strong good water solubility, tackifying and temperature-resistant anti-salt performance and surface-active are good, so that the polymer has good washing oil effect, can be used as the flooding polymers of middle and low permeable reservoir. |
