| titleOfInvention | A kind of ultralow interfacial tension surfactant compound system and preparation method thereof |
| abstract | The invention discloses a kind of ultralow interfacial tension surfactant compound system and preparation method thereof, belong to technical field of surfactant, by percentage to the quality, including 10%~33% host, 7%~23% synergist, 1%~4% stabilizer, surplus are water；Wherein, the host is amphoteric surfactant, and synergist is nonionic surfactant, and stabilizer is anion surfactant.The ultralow interfacial tension surfactant compound system of the present invention is under relatively low dosage, you can oil water interfacial tension is reached 10 within a very short time ‑4 MN/m or the lower order of magnitude, suitable for hyposmosis or super-low permeability reservoir tertiary oil recovery to improve oil recovery factor, it may also be used for well increasing injection and reducing thick oil viscosity, system are free of alkali, will not damaged in use to stratum.Industrial chemicals can be used as to be applied to the industries such as cleaning agent, emulsifying agent, deinking agent.Raw material is easy to get, cheap, functional, is suitable for industrialized production. |
