| titleOfInvention | Containing imidazoline structure terpolymer oil displacement agent and preparation thereof |
| abstract | The present invention relates to a kind of containing imidazoline structure terpolymer oil displacement agent and preparation thereof.This copolymer is by acrylamide (AM), acrylic acid (AA), three kinds of monomer synthesis of oleic imidazolinone derivative (NIGE), and raw material rate of charge is AM:AA:NIGE=6.5:3.5:0.015；The preparation method of terpolymer AM/AA/NIGE oil displacement agent is provided, introduces imidazoline circulus, strengthen copolymer molecule chain rigidity, improve its shear resistant；In hydrophobic long-chain, introduce hydroxyl simultaneously, increase the water solubility of copolymer；This copolymer has good heat and salt resistance and shear stability, and preparation process is simple, and productivity is high, it is possible to preferably improve oil recovery factor for oil field. |
