| titleOfInvention | Water-soluble polymer oil displacement agent |
| abstract | A water-soluble polymer oil displacement agent comprises 20wt% of a polymer monomer, 2-4wt% of a composite initiator ammonium persulfate-sodium bisulfate and 4-6wt% of an emulsifier polyoxyethylene nonyl phenyl ether OP-10; and the polymer monomer comprises acrylic acid (AA), acrylamide (AM), N,N-diallyl-3-pyridinecarboxamide ( DANA) and N,N-dimethyl formamide (DMF). A preparation method of the water-soluble polymer oil displacement agent comprises the following steps: 1, preparing a solution; 2, synthesizing a primary product; and 3, refining the product. The oil displacement agent prepared in the invention is characterize din that a pyridine ring structure monomer is introduced to a polymer molecular chain, so the mechanical performances, the thermal stability and the chemical stability of the polymer are improved; and a hydrophobic long chain is introduced into the polymer molecular chain, and intermolecular association is carried out, so the viscosity and the shear recovery of the polymer are improved. |
