一种新型发泡剂的泡沫稳定性研究

Study on the foam stability of a novel foaming agent

对阳离子表面活性剂CHLB(一种新型发泡剂),采用Waring-Blender搅拌法进行了泡沫性能研究。结果表明,该发泡剂在体系中的最佳浓度为0.90%,具有较好的耐盐性,泡沫性能受上沙溪庙组地层岩屑的影响较小,所能容忍的水侵量约为泡沫基液的2倍,能够承受一定的柴油污染。

The cationic surfactant CHLB,which is a kind of foaming agent. The foam properties’study is using the widely method of Waring-Blender act under different conditions. The results show that the best concentration of the foaming agent is 0. 90%,with good salt tolerance,the less effected by cuttings of Shangshaximiao formation on the foam performance,and the foam can tolerate the invasion of liquid wa-ter,which is about 2 times the base fluid,and can sustain a certain amount of diesel oil pollution.
