More Information
Summary:The invention particularly relates to a nanometer oil-displacing agent and a preparation method thereof, and belongs to the technical field of oil exploitation, and the method comprises the following steps: mixing a biological surfactant, a chemical surfactant, a polymer and a profile control agent to obtain an oil-displacing agent liquid; drying the oil-displacing agent liquid to obtain oil-displacing agent powder; grinding the oil-displacing agent powder to obtain oil-displacing agent particles; mixing the oil-displacing agent particles with a solvent to obtain the nano oil-displacing agent, a physical processing technology is adopted, cost is low, environment friendliness is achieved, the yield is high, the automatic oil finding function is achieved after the viscosity reducer is injected into an oil reservoir along with a well, a stable adsorption layer is formed on a discretized oil-water interface, oil drops are gathered and enter thick oil to destroy colloid and asphaltene molecule winding knots, and t
