| titleOfInvention | Preparation method of polymer microspheres with oil displacement function |
| abstract | The application provides a polymer microsphere with an oil displacement function and a preparation method thereof, wherein the polymer microsphere with the oil displacement function comprises the following components in parts by weight: 30-35 parts of solvent oil; 10-15 parts of an emulsifier; 20-25 parts of a composite monomer; 2-4 parts of a biological surfactant; 0.05-0.1 part of a crosslinking agent; 0.01-0.02 part of initiator; 20-35 parts of water. By introducing the biological surfactant in the preparation process of the polymer microspheres, the interfacial tension of the aqueous solution of the polymer microspheres and the crude oil is greatly reduced, and the defect that the polymer microspheres mainly depend on expanding water flooding waves and expanding the volume to displace the oil is overcome, so that the oil displacement efficiency is improved, and the crude oil recovery rate is further improved. |
