| titleOfInvention | A kind of composite petroleum displacement agent and preparation method thereof |
| abstract | The invention discloses a composite petroleum displacement agent and a preparation method, belonging to the technical field of crude oil exploitation; the raw materials of the displacement agent include: acrylamide, acrylic acid, NaOH, amphoteric surfactant, 1,3-dimethyl-2- Imidazolidinone, 2-acrylamido-2-methylpropanesulfonic acid, allyl cyclohexylbutyrate, trimethylolpropane tris(3-mercaptopropionate) and water; first for acrylamide, acrylic acid, 1,3-dimethyl-2-imidazolidinone, 2-acrylamido-2-methylpropanesulfonic acid were prepolymerized by microwave heating, and then amphoteric surfactant, allyl cyclohexylbutyrate and trihydroxy Methylpropane tris(3-mercaptopropionate) is further polymerized under ultraviolet light irradiation, and then dissolved in NaOH solution; the displacer has good water solubility and stability, and has high temperature resistance and high salt resistance. Excellent, under high temperature conditions, the recovery factor of oil flooding with high salt content is as high as 45% or more. |
