| titleOfInvention | The method that control dynamics condition prepares partial cross-linked partially branched polymer oil displacement agent |
| abstract | The invention discloses a kind of method that control dynamics condition prepares partial cross-linked partially branched polymer oil displacement agent, its main contents includes：By formula material acrylamide, diglycol, polyethylene glycol, methacrylic acid N, N dimethylaminoethyl, potassium peroxydisulfate, sodium hydrogensulfite is dissolved in the deionized water no less than its 1.0 times of mass parts of formula ratio respectively prepares solution；By acrylamide, methacrylic acid N, N dimethylaminoethyls, diglycol solution, polyethylene glycol are added and are placed in 0~60 DEG C of water in the reactor of water-bath, nitrogen is passed through under agitation fully removes oxygen in reactor and solution, add potassium persulfate solution and solution of sodium bisulfite, question response system starts polymerization, and viscosity substantially increases, and stopping is passed through nitrogen and stirring, reaction to be polymerized is constant to temperature, that is, prepares gluey oil displacement agent.Polymer oil-displacing agent with different structure, different performance can be prepared using the present invention, the need for different reservoir medias being met. |
