疏水型二氧化硅粒子对泡沫体系稳定性的影响
Influence of hydrophobically modified silicon dioxide particles on stability of EOR flooding foam
摘要
Abstract
The surface of commercial silicon dioxide particles was hydrophobically modified. The aqueous foams were prepared by stirring mixtures of dodecyl sulfate sodium (SDS) and silicon dioxide particles before or after surface modification. Hydrophobicity of particles, particle additions, concentration of particles adsorbed on the air/water interface and stability of dynamic stretching liquid film were investigated. The results showed that the foamability and foam stability of the original silica/SDS dispersion was better than that of the modified silica particle/SDS dispersion. The foam stability increased with increasing particle addition and it reached a maximum with the particle addition of 0.05% (mass). However, in dynamic stretching conditions, the liquid film can be stabilized by hydrophobically modified silica particles. The stretch length of liquid film reached a maximum at the particles addition of 0. 05%.关键词
