摘　　要：基于油田三次采油对泡沫驱替的要求,对复配体系发泡剂FOR进行性能评价,采用表面张力法测定FOR的临界胶束浓度(cmc),用振荡法测定不同质量分数FOR水溶液及在不同盐溶液中泡沫半衰期。结果表明,FOR在水溶液中cmc约为0.5%,在质量分数为0.8%下具有较长的泡沫半衰期,在盐溶液中泡沫半衰期最高达216 min,在Na Cl,Mg Cl2溶液中泡沫半衰期变化不大,说明该发泡剂性能优良,适用于高矿化度油田泡沫驱替。Performance evaluation on Compound Foaming Agent FOR was carried out based on the need of tertiary oil recovery for foam displacement in oil field,the critical micelle concentration（ cmc） of FOR was determined with surface tensiometry,and the half life periods of foam of the aqueous solutions of different FOR mass fractions and of the salt solutions of different FOR mass fractions were determined with oscillation method. The results of study have shown that the half life period of foam is relatively long when the cmc of FOR in aqueous solution is 0. 5% and the FOR mass fraction of aqueous solution is 0. 8% and that the half life period of foam of FOR-containing salt solution can be as high as 216 min with the half life period of foam of FOR-containing Na Cl solution or Mg Cl2 solution changing little,indicating that this foaming agent has good performance and is suitable for being used for foam displacement in high salinity oilfield.
