| titleOfInvention | Hydrophobically associating polymer sulfonate oil-displacing agent and synthesizing method thereof |
| abstract | The invention relates to an oil-displacing agent and a preparation method thereof, and particularly relates to a hydrophobically associating polymer sulfonate oil-displacing agent. The oil-displacing agent is prepared from the following four monomers: acrylamide (AM), sodium acrylate (NaAA), sulfonate functional monomer NDS and hydrophobic monomer NIMA. According to the polymer sulfonate oil-displacing agent and a preparation method thereof, a long-chain hydrophobic group is introduced to enhance the associating action among molecules and improve water solubility and salinity resistance of a polymer; a five-membered heterocyclic imidazoline structure is introduced, so that the rigidity of a polymer molecular chain can be remarkably enhanced, and the viscosifying capacity, temperature tolerance and shearing resistance of the polymer can be improved; a sulfonate group is introduced, so that the water solubility and salinity resistance of the polymer can be greatly improved. The polymer oil-displacing agent shows good temperature tolerance, salinity resistance and anti-shearing dilutability, and can be used for well increasing the oil recovery. The oil-displacing agent has the advantages of simple synthesizing method, high yield, stable performance and environmental friendliness, and has a relatively good practical application prospect. |
