| titleOfInvention | A kind of polyacrylamide and its preparation method and application |
| abstract | The invention discloses a kind of polyacrylamide and its preparation method and application, this method includes：Under the conditions of solution polymerization, in the presence of initiator and crosslinking agent, a kind of monomer mixture is set to carry out polymerisation in water, it is characterised in that the monomer mixture contains acrylamide, temperature-resistant anti-salt monomer and tertiary amine-type monomer；On the basis of the acrylamide of 100 parts by weight, the consumption of the temperature-resistant anti-salt monomer is 0.5 30 parts by weight, and the consumption of the tertiary amine-type monomer is 0.01 20 parts by weight, and the consumption of the crosslinking agent is 0.00005 0.002 parts by weight.The polyacrylamide provided according to the present invention has profile control and water plugging concurrently and improves oil and water mobility ratio function and can be applied to high temperature and high salt and high heterogeneous reservoir. |
