Surfactant for oil displacement

Surfactant for oil displacement

1、 Application field in the oil exploitation industry, surfactant, as an oil displacement agent, can not only be used alone, but also be combined with polyacrylamide, alkali and other chemicals for binary composite flooding and ternary composite flooding. Surfactant can significantly reduce the interfacial tension between oil and water, promote the desorption and effective dispersion of crude oil from rocks, drive the residual oil, improve oil washing efficiency, and improve oil recovery. 2、 Product characteristics this product can reduce the oil / water interfacial tension value to 10-3 ~ 10-5mn / m. temperature and salt resistant groups are introduced in the product synthesis process to increase the adaptability to high temperature and high salt reservoirs.
