METHOD OF OIL PRODUCTION |
| abstract |
A method for extracting oil from underground oil fields, in which an aqueous composition containing at least one water-soluble hydrophobic-associative copolymer is injected into an oil field through at least one injection well with a field temperature of 20-120 ° C, and at least one production well extracts crude oil, and the water-soluble copolymer contains at least acrylamide or its derivatives, as well as a mixture containing at least two amphiphilic m kromonomera. |
