Product category: anionic surfactants

Product description: This product is an anionic surfactant prepared by sulfonation, neutralization and concentration of a specific crude oil fraction. Its oil-based structure consists of linear alkylbenzene, branched alkylbenzene and alkylnaphthenic benzene, which has a good interfacial action with naphthenic base oil, and can reduce the oil and water interfacial tension to ultra low in a short time. The product has excellent resistance to calcium and magnesium ions, and can be used in oil fields with formation water salinity of 500-30000mg/L. This product has good wetting reversal ability, anti adsorption ability and moderate oil emulsification ability, can greatly enhance oil recovery. This product has been used in Gudao and Gudong Oil Production Plant of Shengli Oilfield for more than 10 years. The water content of the produced liquid can be reduced from 98% to 85%, and have achieved good effects of decreasing water cut and increasing oil production

Appearance: brown viscous liquid
