摘要
应用气流法研究了三元复合驱用的阴离子型表面活性剂ORS -4 1与非离子型表面活性NOS的泡沫性能 .结果表明 :在蒸馏水中 ,当表面活性剂的质量分数为 0 .2 %~ 0 .6%时 ,ORS -4 1的起泡能力高于NOS ,但其稳泡性小于NOS ;在碱水中 ,NOS的泡沫性能明显优于ORS -4 1;在碱、聚合物共存条件下 ,由ORS -4 1构成的三元复合体系的泡沫性能得到明显改善 ,但仍不如由NOS构成的三元复合体系的性能 .
The foaming properties of ionic and nonionic surfactants ORS-41 and NOS which are used as threecompound-combination flooding are studied by gasflowmethod..The results show that the foaming property of ORS-41 is better than that of NOS ,but the foaming stability of the latter is better as the surfactant mass fractions is in 0.2%~0.6%. The foaming ability of NOS is better than that of ORS-41 in alkaline solution. In the condition of alkaline/polymer ,the foaming properties of ORS-41 combination system have been improved a lot. But the foaming stability of it is not as good as that of NOS. It is very important for the surfactant selection of foam combination flooding.
