| titleOfInvention | Low-tension polymer microemulsion system for oil reservoir deep profile control and flooding and preparation method thereof |
| abstract | The invention relates to a low-tension polymer microemulsion system for oil reservoir deep profile control and flooding and a preparation method thereof, and mainly solves the problems that the conventional emulsifier for reversed-phase microemulsion polymerization in the prior art is large in dosage and has no oil-washing effect. The invention replaces or partially replaces the conventional emulsifier by the alkyl amide betaine surfactant shown in the structure of formula (1), wherein R 1 Aliphatic hydrocarbons of C1-C18; r 2 Is C2-C10 alkylene, and is prepared by reverse microemulsion through polymerization reaction under the action of redox composite initiator; the reverse microemulsion comprises the following components in parts by weight: 50 parts of an oil-soluble solvent; 3-20 parts of an emulsifier; 10-70 parts of an acrylamide monomer; 0.5-20 parts of a temperature-resistant salt-resistant monomer; 10-60 parts of water, so that the microemulsion system has a technical scheme of good profile control and water shutoff effects and good interfacial activity, the problem is well solved, and the system can be used as an oil displacement agent and a deep water shutoff profile control agent to be applied to tertiary oil recovery in an oil field to improve the crude oil recovery rate.
