| description | The invention discloses a slow-release polymer microsphere extraction agent with a core-shell anisotropic structure and a preparation method thereof, the slow-release polymer microsphere extraction agent with the core-shell anisotropic structure comprises a water-soluble polymer shell and an oil-soluble high-molecular polymer core wrapped in the water-soluble polymer shell, the oil-soluble high-molecular polymer inner core is internally wrapped with a surfactant for oil displacement. The slow-release polymer microsphere extraction agent with the core-shell anisotropic structure has multiple effects of common polymer microspheres, an organic resin plugging agent, a crude oil disassociation agent and a surface active oil displacement agent, and has the multiple effects of plugging water (profile control) when encountering water, emulsifying crude oil (washing oil) when encountering oil and combining plugging and flooding. The problems that polymer microspheres are not resistant to shearing, the profile control |
