Microemulsion oil displacement agent
Product Description
Microemulsion oil displacement agents are produced by shear emulsification of water-soluble surfactants and water to solubilize oil-soluble surfactants. These products not only feature low interfacial tension and high oil-displacement efficiency, but also exhibit excellent solubilization performance, high resistance to mineralization, and emulsion stability. The minimum interfacial tension of the product can be reduced to below 10⁻⁵ mN/m.
This product is primarily used for surfactant oil displacement and single-well production, and can also be used in combination with polymers and alkalis.
Product Features
1. It is readily biodegradable, mild in nature, and has good compatibility.
2. The product’s minimum interfacial tension can be reduced to below 10⁻⁵ mN/m.
3. It features excellent solubilization properties, high resistance to mineralization, and emulsion stability.
4. It accelerates the desorption of crude oil from rock and promotes effective dispersion, thereby driving out residual oil, improving oil washing efficiency, and ultimately increasing recovery rates.
Ultra-low surface tension
Application
This product is primarily used for surfactant-assisted oil recovery and single-well production; it can also be used in combination with polymers and alkalis.

Directions for Use
1. The oil displacement agent formulation can be adjusted based on oil and water samples from the target block to achieve an interfacial tension of 10–3 or lower.
2. Prepare a 0.3–1.0% aqueous solution using reinjection water from the target block and inject it directly into the formation.
