| titleOfInvention | Partially crosslinked and partially branched copolymer oil displacement agent and preparation method thereof |
| abstract | The invention provides a partially crosslinked and partially branched copolymer oil displacement agent, which comprises the following raw material components in parts by weight: 100 parts of acrylamide, 0.015-0.1 part of potassium persulfate, 0.002-0.06 part of tetramethylethylenediamine, 0.005-0.3 part of allyl compound and 0.0002-1 part of cross-linking agent. The invention also provides a preparation method of the partially cross-linked and partially branched copolymer oil-displacing agent, which comprises the process steps of solution preparation and polymerization reaction preparation of the oil-displacing agent. The invention provides the polymer oil displacement with good viscoelastic property and aging resistance for tertiary oil recovery. |
