Abstract
Sulfobetaine surfactants were summarized.The sulfobetaine surfactants possess good tolerance to acids,alkalis and salts with high concentration and high temperature,and excellent compatibleness with other surfactants.The progress in the current research and tendency of the surfactants used in tertiary oil recovery were analyzed.The synthesis and synergistic effects of the sulfobetaines used in tertiary oil recovery and alkali-free binary combination flooding systems with sulfobetaines were reviewed.The existing problems in the practical promotion were also discussed.Furthermore,the application and main development orientations of the sulfobetaine surfactants in tertiary oil recovery were prospected.
