| titleOfInvention | A kind of surface-active polymer oil-displacing agent and preparation method thereof |
| abstract | The invention discloses a kind of surface-active polymer oil-displacing agent and preparation method thereof, belong to high molecular polymer oil-displacing agent technical field; Described surface-active polymer oil-displacing agent introduces heatproof, shear-stable 2-propenyl acid amides-2-methylpropanesulfonic acid group on high polymer main chain, with salt tolerant, resistance to high salinity polymerisable surface active monomer maleic acid-(Z)-3-iodo-3-Trifluoromethyl-1-butyl allyl ester sodium salt, then carry out copolymerization with acrylamide under certain conditions and form; Surface-active polymer oil-displacing agent of the present invention has good water-soluble, increasing stickiness, heat and salt resistance and anti-shear performance, easy to use, cost is low, can effectively improve sweep efficiency and oil displacement efficiency, oil field Sustainable high yield can be kept, especially can carry late high water content period Exploitation Level of Oilfield, there is good application prospect. |
