Abstract
A review is given about the research progress of four kinds of sulfonate surfactants including petroleum sulfonates,heavy alkyl benzene sulfonates,aliphatic alcohol polyoxyethy-lene ethers sulfonates and sulfonic Gemini surfactants as oil displacement agents.The problems in oilfield applications and the future directions of these four kinds of surfactants are pointed out.The mechanisms for oil-water emulsion to improve oil recovery are elaborated.The factors which influence the emulsifying capacity of surfactants are preliminarily analyzed.Moreover,it is emphasized that studying the properties of surfactants from the perspective of molecular structure is of significance.
