More Information
Summary:The invention discloses an emulsion profile control and flooding agent and a preparation method thereof. The emulsion profile control and flooding agent comprises the following components: an oil phase, an emulsifier, an interfacial film stabilizer and the balance being water, wherein the emulsifier is a surfactant compound system and comprises an anionic surfactant, a cationic surfactant and a nonionic surfactant; the interfacial film stabilizer is nanoparticles. The used emulsifier is an anionic/cationic/nonionic surfactant compound system, and the residual oil is easier to emulsify throughthe synergistic effect of the three components; meanwhile, due to the electrostatic interaction, the surfactant is more uniformly distributed on an oil-water interface film, so that the formation andthe stability of an oil-in-water emulsion are facilitated; besides, the selected water-based nano silicon polymer particles are insensitive to the pH value of the system, and the nano particles and surfactant molecules can for
