Abstract: The foaming behavior and its influence of an anionic sulphonate foaming agent(FA220) were researched.It was found that both of the foaming volume and half-time of foam reach the highest point when the concentration of foaming agent is 0.6%;FA220 has a good ability of resistance to Mg²⁺ ,NaCl and Ca²⁺ bring some neglect impact on the stability of foam and very little impact on the foaming volume; the addition of polymer improves the foam system stability and decreases the foaming volume,the foaming volume and half-time of foam make better result when the concentration of polymer was between 0.3~0.8g/L;oil has obvious defoaming effect,the defoaming effect become stronger with the increase of oil saturation.

摘要： 对一种阴离子磺酸盐起泡剂(FA220)的起泡性能及影响因素进行了实验研究。结果表明,在起泡剂质量分数为0.6%时,起泡剂的起泡体积和半衰期均达到最高值;起泡剂FA220具有较好的耐Mg²⁺ 能力,NaCl和Ca²⁺ 对其稳定性具有一定的负面影响,但对其起泡体积影响不大;聚合物的加入会增加泡沫体系的稳定性,但会减小其起泡体积,当聚合物质量浓度在0.3~0.8g/L时,起泡体积和半衰期均可取得良好的效果;原油具有明显的消泡作用,含油饱和度越大,消泡作用越明显。
