Can nano-materials and surfactants be used in tertiary oil recovery?

The combination of nano-materials and surfactants has been applied in many aspects of tertiary oil recovery, such as stabilizing oil-water emulsion and improving interfacial activity of oil displacement agent, etc. Table 9 briefly summarizes the application of the compound system of nano-materials and surfactants, and details are as follows.

Can ionic surfactants improve oil displacement efficiency?

As common oil displacement agents, ionic surfactants and non-ionic surfactants can theoretically greatly improve oil displacement efficiency and enhance oil recovery. However, in practical applications, when used alone, the interfacial tension of oil/water can hardly be reduced to the expected level.

Can molecular simulation help tertiary oil recovery?

It is hoped that the molecular simulation system can provide feasible conditions for the experimental system and industrial exploitation by studying the molecular aggregation behavior at the oil/water interface, and finally provide relevant theoretical guidance for the design of new oil displacement agents in the tertiary oil recovery. 2.

Can nanoparticles and surfactant reduce interfacial tension in tertiary oil recovery?

Table 9. Application of compound system of nanoparticles and surfactant in tertiary oil recovery. Nanoparticles can reduce the interfacial tension after adsorption, and surfactants can also reduce the interfacial tension. How to combine them to achieve the maximum effect of reducing the interfacial tension has always been the focus of attention.

What is fluorocarbon-modified polyacrylamide copolymer?

Fluorocarbon-modified polyacrylamide copolymer is a kind of material used in high-temperature and high-salt reservoirs, so it has the potential to be used as polymer for enhanced oil recovery.

What is the main reaction between polyacrylamide and water soluble phenolic aldehyde?

The results showed that the molecular simulation result was consistent with the experimental result, which proved that the condensation reaction between polyacrylamide and water-soluble phenolic aldehyde was the main reaction in the system.
