利用Warning Blender方法测定SiO2+SDS泡沫体系的泡沫性能,确定SiO2纳米颗粒的最佳使用浓度,并研究不同温度和矿化度对泡沫性能的影响。利用岩心驱替实验装置对比SDS和SiO2+SDS两种不同泡沫体系对岩心的封堵、调剖和驱油性能。利用微观可视化玻璃刻蚀模型,对比水驱、SDS泡沫体系以及SiO2+SDS泡沫体系对盲端油的驱替效果。室内实验结果表明,SiO2+SDS泡沫体系比单一SDS泡沫体系具有更强的稳定性,能够明显提高泡沫的封堵、调剖及驱油能力,增加盲端油的驱替效果。

The perfOrmances Of SiO2+SDS fOam system were investigated by using Warning Blender methOd, thrOugh which the Op-timum amOunt Of SiO2 nanOparticles was determined. And the influences Of temperature and salinity On fOam prOperties were stud-ied as well. The plugging ability, diversiOn ability, and Oil displacement perfOrmance fOr SDS and SiO2+SDS fOam systems were characterized and cOmpared by means Of the cOre displacement experimental facilities. AlsO the micrOscOpic visualizatiOn test was cOnducted tO cOmpare the Oil displacement perfOrmance Of water flOOding, SDS and SiO2+SDS fOam systems On the dead-end pOres. The results shOw that SiO2+SDS fOam system is mOre stable than SDS fOam system, which can significantly imprOve the plugging, diversiOn, and Oil displacement ability. AlsO the displacement effect fOr dead-end pOres is increased as well.
