| titleOfInvention | A polymer oil displacement agent based on fluorine-containing hyperbranched multi-arm polyacrylamide polymer |
| abstract | The invention discloses a polymer oil displacement agent based on a fluorine-containing hyperbranched multi-arm polyacrylamide polymer, that is, the application of a fluorine-containing hyperbranched multi-arm polyacrylamide polymer in polymer oil displacement. The structural formula of the fluorine-containing hyperbranched multi-arm polyacrylamide polymer is shown in formula I, wherein the core A is the hyperbranched polyglycidyl ether with hydroxyl groups at the end; the arm B is composed of acrylamide, sodium acrylate , a copolymer formed from a fluorine-containing hydrophobic monomer and a zwitterionic choline functional monomer; in the copolymer, a polyacrylamide segment, a sodium polyacrylate segment, a polyfluorine-containing hydrophobic segment and a polyzwitterionic choline The functional segments are connected sequentially, and the other end of the polyacrylamide segment is grafted onto the core A. The three-dimensional spherical hyperbranched multi-arm structure of the fluorine-containing hyperbranched multi-arm polyacrylamide polymer of the present invention and the fluorine-containing hydrophobic segment can improve the shear resistance of the polymer, and the zwitterionic choline functional segment endows the polymer Good salt resistance. |
