High-temperature oil displacement agent
Product Description
High-temperature oil displacement agents are composed of anionic and nonionic surfactants. These products have low oil-water interfacial tension and can effectively improve reservoir wettability, changing it from oil-wetting to water-wetting or neutral wetting, thereby achieving effective crude oil stripping and improving oil recovery efficiency. At the same time, the products exhibit good temperature resistance and resistance to mineralization, making them suitable for multi-cycle steam injection, thermochemical composite oil displacement, steam flooding, as well as conventional water flooding and ternary composite flooding.
Product Features
1. Easily biodegradable, mild in nature, and compatible with other agents.
2. Forms a tight adsorption film at the oil-water interface, reducing the interfacial tension to 10⁻¹ to 10⁻² mN/m.
3. Withstands temperatures up to 350°C and can be used in combination with steam for steam injection and steam flooding.
4. It accelerates the desorption of crude oil from rock and promotes effective dispersion, driving out residual oil and improving oil washing efficiency, thereby increasing recovery rates.
After aging at 250°C, 300°C, and 350°C, the high-temperature oil displacement agent is clear and transparent, with no residue.
Application
Suitable for steam injection, steam-assisted oil recovery, thermochemical enhanced oil recovery, as well as conventional water injection and ternary enhanced oil recovery.
