Product features
The surfactant is composed of biological surfactant, Gemini surfactant and anionic surfactant in a certain proportion. The product has the ability to form ultra-low interfacial tension with crude oil, as well as the ability to disperse, emulsify and strip crude oil.
The surfactant has the characteristics of high surface activity, good water solubility, low dosage, temperature resistance and salt resistance, which can be widely used in single well stimulation, cold recovery of heavy oil and surfactant - polymer composite flooding technology.
