Introduction of the High-efficiency Surfactant Compound System from Huizhi Holdings

Polymer flooding, binary and ternary combination displacing are the main measures to further control oil recovery costs and increase oil recovery in the later stage of oilfield water displacing. Relying on the professionaltechnology and larger scale, Huizhi holdings has continuously made technological breakthroughs in the field of polyacrylamide products for flooding and has launched a variety of salt-resistant product types of polyacrylamide for flooding. The high-efficiency surfactant compound system developed by Huizhi can be compounded with polyacrylamide, alkali and other chemicals for binary and ternary compound flooding.


Surfactant Chemical Product from Huizhi Holdings

Surfactants, also known as interfacial active agents, are substances that can significantly reduce the surface tension of the target solution, which can reduce the surface tension between two liquids or liquid solids. A wide variety. The most typical example is soap, which has the effect of decomposition and infiltration, and is widely used. Surfactants are generally organic amphoteric molecules with hydrophilic and hydrophobic groups, usually amphiphilic organic compounds containing hydrophobic groups (" tail ") and hydrophilic groups (" head "). Therefore, they are soluble in both organic solvents and water.
