| titleOfInvention | A kind of polymer and its preparation method and application with surface active function |
| abstract | The present invention relates to oil recovering fields, disclose a kind of polymer and its preparation method and application with surface active function, the polymer contains structural unit A, structural unit B and structural unit C, wherein, the structural unit A is the structural unit with structure shown in formula (1), the structural unit B is the structural unit with structure shown in formula (2), and the structural unit C is the structural unit with structure shown in formula (3).The present invention introduces the polymerisable monomer with surface-active on macromolecular chain, its ether chain structure determine the copolymer of synthesis have stronger hydrolytic resistance and thermal stability, the ageing-resistant performance of polymer can be improved, the surface tension and interfacial tension of polymer solution are substantially reduced simultaneously, so that polymer has good surface-active, increase-volume emulsification and washing oil ability, and then improve oil recovery factor. |
