Abstract
Provided in the present invention a method for evaluating the mixing effect of a COoil-displacing and mixing agent, characterized in measuring the volume expansion of a CO-oil interface when pressure is gradually increased, drawing a mixed-phase percentage-pressure curve (δ-P curve), and evaluating the mixing effect of the COoil-displacing and mixing agent by means of comparing the characteristics of the δ-P curve. Further provided in the present invention is a method for initially screening a COoil-displacing and mixing agent.
