| titleOfInvention | Polyacrylamide microsphere for profile control and preparation method thereof |
| abstract | The invention discloses a polyacrylamide microsphere for profile control and a preparation method thereof, the polyacrylamide microsphere for profile control is prepared by carrying out polymerization reaction on reversed-phase microemulsion under the action of a redox composite initiator, and the reversed-phase microemulsion comprises the following components in parts by weight: 10-50 parts of acrylamide, 10-20 parts of N, N-dimethylacrylamide, 2-15 parts of emulsifier, 20-60 parts of oily solvent, 10-50 parts of water, 0.01-2 parts of cross-linking agent, 30-60 parts of lignin and 5-10 parts of biological collagen. The preparation method of the invention forms a double interpenetrating network of the glue compound and the polyacrylamide, the network density is increased, the initial expansion rate of the polyacrylamide microspheres is inhibited, along with the extension of the expansion time, the degradation of the glue compound is accelerated under the high-temperature, high-salt and actually applied alkaline environment, the double interpenetrating network is released, the expansion is accelerated, and the slow expansion phenomenon occurs. |
