| titleOfInvention | A kind of hydrophobic associated polymer and preparation method thereof |
| abstract | The invention discloses a kind of for oil field fracturing fluid and improves the hydrophobic associated polymer and preparation method thereof of recovery ratio, which is a kind of thickener.Preparation method includes: that 0.2 mole of Bromofume is dissolved in acetone by (1), 0.1 mole of dimethylaminoethyl methacrylate is added dropwise into acetone soln under agitation, it reacts 4 hours at room temperature and obtains N, N- dimethyl bromoethyl methylacryoyloxyethyl ammonium bromide intermediate；(2) the erucyl amide propyl-dimethyl tertiary amine of 0.05 mole of intermediate and 0.055 mole is added in ethyl alcohol, reacts 24 hours at room temperature, obtains polymerizable hydrophobic monomer；(3) hydrophobic monomer is add to deionized water with acrylamide, leads to nitrogen half an hour, is warming up to 45~60 DEG C and initiator is added, 6~8h of polymerization reaction obtains hydrophobic associated polymer.The association polymer has good tackifying ability, and prepares simply, in oil field fracturing fluid and improves in recovery ratio with good application prospect. |
