Title:
SURFACTANT COMPOSITION FOR OIL DISPLACEMENT IN HIGH-TEMPERATURE AND HIGH-MINERALITY OIL RESERVOIRS
Document Type and Number:
WIPO Patent Application WO/2023/284178
Kind Code:
A1
Abstract:
A surfactant composition for oil displacement in high-temperature and high-minerality oil reservoirs, comprising a primary agent, a synergist and a cosolvent. It has good interfacial activity, can further reduce oil-water interfacial tension, and has relatively strong solubilizing and emulsifying, interaction, and synergistic effects; it has uniform and stable systems, continuous and stable oil displacement performance, and can effectively improve oil displacement efficiency.
