| titleOfInvention | A kind of cladodification hydrophobic associated polymer oil displacement agent and preparation method thereof |
| abstract | The invention discloses a kind of cladodification hydrophobic associated polymer oil displacement agent and preparation method thereof, this Polymer Used For Oil Displacement is formed by acrylamide, sodium acrylate, hydrophobic monomer and functionalization backbone monomer copolymerization, described hydrophobic monomer be dimethyl-allyl to alkyl benzyl ammonium chloride, described functionalization backbone monomer is that 2 generation polyamide-amine dendrimer backbone monomer react in dimethyl sulfoxide solution with maleic anhydride or acrylic anhydride and formed.The present invention utilizes the branchedness of polyamide-amine dendrimer skeleton, strengthen Interchain interaction and reduce the flexibility of molecule, and rely on hydrophobic group association in aqueous on strand, improve the tackifying ability of low-molecular weight polymer solution, its preparation method principle is reliable, easy and simple to handle, the polymer of synthesis still has good tackifying ability under high temperature, high salinity and strong shear action, has wide market prospect. |
