China U niversity of Geosciences, School of the Earth Sciences and Resources, Beijing 100083, China; 2. Geosciences Research Institute, Shengli Oilfield Company, SINOPEC, Dongying 257015, China) Abstract: A kind of high temperature foaming agent with a strong foaming ability and good stability, DHF1, was developed by evaluating the foaming ability of the surfac tants produced. It was indicated that DHF1 has stable chemical properties and has good sealing profile control capabilities on steam drive after 72 h of aging at 300 . Further more, it still takes effect in pro
