Product Introduction
Surfactants for oil displacement are composed of a combination of various surfactants, and the product has the characteristics of low dosage, temperature resistance, salt resistance, and good adsorption resistance. At the same time, it has high oil washing efficiency, solubilization and other effects, which can reduce the interfacial tension between oil and water, turn residual oil into flowable oil, and change the wettability of rock surface, increase the dispersion of crude oil in water, promote the aggregation of crude oil into oil bands, thereby changing the interfacial state and flowability of the system, and improve crude oil recovery.

Application
This series of products is mainly used for enhancing oil recovery in conventional oil reservoirs, high wax oil reservoirs, high-temperature and high salt oil reservoirs through binary/heterogeneous composite flooding, ternary composite flooding and other projects, and is implemented in the field according to the composite flooding scheme. The product has strong targeting, and different blocks and reservoir conditions are suitable for different products. We can carry out customized research and development according to different oil-water conditions and provide supporting products.
