Mixed gemini depressurization and injection enhancement agent
Product Description
After the mixed gemini depressurization and injection enhancement agent is injected into the formation, strong electrostatic interaction via ionic bonds enables surfactant molecules to adsorb onto rock surfaces where partial oil film detachment has occurred. This reduces the adhesion of crude oil to rock surfaces, alters the wettability of rock surfaces and lowers the seepage resistance of fluids. The crude oil stripped from rock surfaces is dispersed into tiny oil droplets under the action of surfactants, which improves the flow capacity of crude oil through pore throats. Consequently, the permeability of the reservoir is enhanced, the formation is unblocked, the fluid supply capacity of oil wells is restored, and normal water injection in water wells is realized.
Product Features
1. It exhibits strong electrostatic interactions via ionic bonds.
2. It forms a tight adsorption film at the oil-water interface, where the interfacial tension can reach 10⁻² mN/m.
3. It achieves a high oil recovery rate, exceeding 40%.
4. It adsorbs onto rock surfaces where the oil film has partially peeled off, reducing the adhesion of crude oil to the rock surface and altering the wettability of the rock surface.
Application
Clear the formation to restore the oil well’s fluid supply capacity and enable normal water injection into the water well.

Directions for Use
1. When the proportion of sensitive minerals in the reservoir is ≥5%, an appropriate amount of anti-swelling agent should be added to prevent clay swelling. Compatibility tests should be conducted in advance on the anti-swelling agent and the surfactant used for pressure reduction and enhanced injection.
2. Calculate the chemical injection volume based on the reservoir thickness, porosity, and treatment radius. Before use, prepare a 0.5%–2% aqueous solution of the surfactant used for pressure reduction and enhanced injection, and inject it directly into the reservoir. After completion of the operation, allow the well to stand for 1–3 days to allow the chemical to react, then begin water injection.
3. Online injection in conjunction with long-term reinjection water yields better results; the recommended chemical concentration is 0.3%.
