| titleOfInvention | Crosslinking gradual change swellable polymer microballoon and preparation method thereof |
| abstract | The present invention provides a kind of crosslinking gradual change swellable polymer microballoon and preparation method thereof, mainly solve under the conditions of in prior art, conventional oil field polymer microballoon exists high temperature and high salt easily aquation, expand uncontrollable and to high permeability zonal isolation weak effect problem.The present invention is by using crosslinking gradual change swellable polymer microballoon, and described polymer microballoon is the polymer microballoon formed through radical polymerization in the presence of crosslinking agent by monomer；Described monomer includes acrylamide and/or other water-soluble monomer and heat-resisting/hydrophobic monomers as shown in the formula (I)；Wherein, R 1 And R 2 Each independently take from hydrogen atom, methyl or ethyl；R 3 For C 1 ~C 16 Alkoxyl or thiazolinyl beyond the technical scheme of alkyl preferably solve this problem, can be used in tertiary oil production in oil field operation. Formula (I). |
