Abstract

The ASP flooding is a highly effective tertiary oil recovery method, through the synergistic action of alkali, surfactant and polymer three substances, the ultra-low interfacial tension is formed between the displacement system and the crude oil, meanwhile the polymer makes the system has a higher viscosity, so the ASP flooding can enlarge swept volume and improve washing oil efficiency, thus increasing the ultimate recovery ratio of the oil layer to a greater extent. Since entering industrial application, as the production scale has been expanding, the demand for chemicals, especially surfactants, has increased year by year, due to technology limitations; the increase in demand has caused surfactant performance to be unstable, and the detected interfacial tension cannot meet the design requirements of scheme, which cause the oil recovery ratio of the oil layer to be affected to different degrees, therefore, it is necessary to study the relationship between the different interfacial tensions of the surfactant and the recovery ratio, and understand the relationship between the interfacial tension and the improvement extent of recovery ratio. This paper starts from the oil displacement mechanism of ASP flooding, combines the laboratory tests and numerical simulation research results, gives effect of different interfacial tension on the recovery ratio of the second type oil layer, and provides a theoretical basis for the evaluation of the development effect of the oil layer ASP flooding.
