Abstract:
Disclosed in the present application a nano oil displacement agent, a preparation method therefor, and an application thereof. The nano oil displacement agent is characterized by comprising: a nanomaterial, a surfactant, a water-soluble polymer, and water, wherein the water-soluble polymer covers the periphery of the nanomaterial. The nano oil displacement agent is a temperature-resistant and salt-resistant oil displacement agent, and ensures that a functional nano dispersion liquid does not flocculate or precipitate within a certain temperature and salinity range; the water-soluble polymer can be slowly decomposed under the conditions of high temperature and high salt, and meanwhile, the nanomaterial is released, so that the functional nanomaterial plays a role.
