Abstract: Sulfonate oligomeric surfactants have attracted considerable interest because of their excellent interface activities，salt resistance and temperature tolerance. The paper was aimed to review the synthesis of sulfonate oligomeric surfactants based on three introducing methods (monomer connecting method，introducing hydrophobic chains or polar heads) of hydrophile and lipophilic groups in last decades，and to briefly introduce its physicochemical properties (surface/interface tension，critical micelle concentration，etc) and application performances，including emulsion visbreaking，bactericidal activity，and displacement efficiency. It shows increased researches on the structure-function relationship of the sulfonate oligomeric surfactants for developing novel products with wide excellent cost-effective performance by molecule design method. The synthesis process of sulfonate oligomeric surfactants and the displacement systems consisting of the product，other types of surfactants，and polymer should be optimized for its industrial applications in the tertiary oil recovery.
