Abstract: Foaming of foam agents and instability of stabilizing performance in high temperature has hampered the widespread application of steam foam flooding technology. Aiming at these problems, a series of anionic sulfonate foam agents are synthesized by reactions of olefin sulfurization, alkylation and neutralization. The evaluation results of these agents show that the increasing of sulfonate will benefit for enhancing the temperature resistant of foam agent, and with the rise of lipophilic group, the performance of foam power is cut down and foam stability is improved, and with more hydrophilic groups, the foam power is cut down, but the high temperature resistant is strong than others and can be used in larger scale of temperature. The double sulfonate foam agents would be used widely in the field.
