[0034] The present invention provides the preparation method of the nanoemulsion oil displacement agent described in above-mentioned scheme, comprises the steps:
[0035] (1) under the condition of nitrogen protection, the cross-linking agent and the monomer alkali-water mixture are mixed to obtain the monomer aqueous phase solution;
[0036] (2) Mineral oil is mixed with an emulsifier to obtain an oil phase;
[0037] (3) adding the oil phase obtained in the step (2) to the aqueous monomer solution obtained in the step (1) for emulsification to obtain an emulsion;
[0038] (4) under the condition of nitrogen protection, the oxidant, reducing agent and the emulsion obtained in the step (3) are mixed and polymerized to obtain a nanoemulsion oil displacement agent;
[0039] There is no limitation on the order of the steps (1) and (2).
[0040] In the invention, the cross-linking agent is mixed with the monomer alkali-water mixed liquid under the nitrogen protection condition to...
