摘要:本发明涉及一种泡沫驱油用粘土稳泡复合剂及其制备方法与应用,包括如下重量份的原料组成:十二烷基苯磺酸钠0.2~0.9份,粘土颗粒1~10份,水100份;所述的粘土颗粒的粒径为25~100μm。本发明的泡沫驱油用粘土稳泡复合剂,由于加入了疏水性的粘土颗粒,使得固相颗粒在液膜表面和液膜层内附着,形成刚性的致密外壳,提高了泡沫液膜的强度,抑制了液膜的排液,防止液膜的变薄,从而提高了泡沫的起泡体积,增加了泡沫的半衰期。

主权项:一种泡沫驱油用粘土稳泡复合剂,其特征在于包括如下重量份的原料组成:十二烷基苯磺酸钠0.2~0.9份,粘土颗粒1~10份,水100份;所述的粘土颗粒为粒径25~100μm的膨润土颗粒。
