NOVELTY - Preparing an amphiphobic sulfonated carbon nanotube/modified graphene oxide wetting reversal agent, comprises adding carbon nanotubes into the acid solution, ultrasonically treating in a water bath; the amount of carbon nanotubes added is 3-6.5 g/l; adding deionized water, heating and stirring, allowing the mixed solution to stand and separate, washing and drying the sample to obtain sulfonated carbon nanotubes; mixing sulfonated carbon nanotubes and graphene oxide into deionized water, sonicating, heating, stirring, washing and drying the sample to obtain modified graphene oxide 1; (iii) ultrasonically dispersing the modified graphene oxide 1 together with the organic solution and the silane coupling agent so that the concentration of the modified graphene oxide 1, adjusting the pH to be acidic, heating and stirring to obtain a modified graphene oxide 2 solution. USE - The amphiphobic sulfonated carbon nanotube/modified graphene oxide wetting reversal agent is used to transform the reservoir to make the reservoir wettability change from hydrophilic-lipophilic to amphiphobic, strongly amphiphobic or super amphiphobic. DETAILED DESCRIPTION - Preparing an amphiphobic sulfonated carbon nanotube/modified graphene oxide wetting reversal agent, comprises (i) adding carbon nanotubes into the acid solution, ultrasonically treating in a water bath at room temperature, where the acid solution is a mixed acid solution with a volume ratio of sulfuric acid and nitric acid at 2-4:1-2; the amount of carbon nanotubes added is 3-6.5 g/l; adding deionized water, heating and stirring, allowing the mixed solution to stand and separate, washing and drying the sample to obtain sulfonated carbon nanotubes; (ii) mixing sulfonated carbon nanotubes and graphene oxide into deionized water at a mass ratio of 1-3:1-3, sonicating, heating, stirring, washing and drying the sample to obtain modified graphene oxide 1; (iii) ultrasonically dispersing the modified graphene oxide 1 together with the organic solution and the silane coupling agent so that the concentration of the modified graphene oxide 1 is 1-4.5 g/l, adjusting the pH to be acidic, heating and stirring to obtain a modified graphene oxide 2 solution; the organic solvent is absolute ethanol, tetrahydrofuran or acetone; the silane coupling agent is methacryloxymethyltriethoxysilane, acryloyloxymethyltrimethoxysilane or vinyltrimethoxysilane; (iv) ultrasonically mixing modified graphene oxide solution, N,N-dimethylformamide, emulsifier, and fluorine-containing monomer, where the emulsifier is gum arabic, sodium perfluorononenyloxybenzenesulfonate or sodium dodecylbenzenesulfonate, the fluorine-containing monomer is methacrylic acid, dodecafluoroheptyl, tridecafluorooctyl methacrylate or 2-perfluorooctyl ethyl acrylate; adding an initiator, heating and stirring, and carrying out polymerization reaction.
