中文摘要:
      泡沫体系具有可注入性强、注入方式多样、成本较低等优点,在低渗透油田调剖应用方面越来越受到重视。但在实际应用中泡沫易受地层高温、高盐、高压等环境影响,泡沫稳定性大大降低。本文介绍了目前纳米颗粒稳定泡沫体系的研究与应用进展,分析了纳米颗粒稳定泡沫的机理,提出通过化学修饰方法改变纳米颗粒表面特性,使修饰后的纳米颗粒同时具有发泡和稳泡作用的建议。这种具有高稳定性、高机械强度和可地层内自生的一体化发泡/稳泡剂可用于低渗透油田泡沫调剖。图7 表1 参21
英文摘要:
      Due to high injectivity,various injection mode and low cost,foam system had been paid more and more attention on the application of profile control in low permeability oilfield. However,foams were vulnerable to high temperature,high salt,high pressure and other environmental impacts in the practical application,which could reduce the foam stability. The current research progress and application of nanoparticle stabilized foam system was summarized in this paper,and the mechanism of nanoparticle in stabilizing foam was analyzed. It was suggested that a integrated foaming and stabilizing agent could be obtained by changing the surface property of nanoparticle. This kind of integrated foaming and stabilizing system,with high stability and mechanical strength,and generating in formation,would have an important influence on foam profile control technology in low permeability oilfield.
