More Information
Summary:The invention relates to research of a binary compounding system capable of generating an ultralow interfacial tension, and relates to a binary oil-displacing agent which is obtained by using a conventional anionic surfactant to compound with a series of laboratory synthesized quaternary ammonium salt type gemini surfactants of 10-20-10, 12-2-12, 16-4-16 and the like, wherein the oil-water interfacial tensions of the conventional anionic surfactant and the laboratory synthesized quaternary ammonium salt type gemini surfactants are tested, and the results show that the gemini surfactants with suitable structures and the conventional anionic surfactant can reduce the interfacial tension between crude oil and water to an ultralow value at a specific compounding proportion and show relatively good interfacial activity; and the oil-water interfacial tension of the binary oil-displacing agent obtained after compounding the gemini surfactants with the conventional anionic surfactant can be as low as E-4mN/m, and the binary oil-displacing agent shows relatively good interfacial activity, and has a relatively good application prospect in the aspect of improving the crude oil recovery ratio.
