摘要:
为进一步提高聚驱后采收率,结合聚驱后油藏特征,构筑具有自适应堵调驱功能的微纳米颗粒三相泡沫体系,通过黏度、界面、泡沫和堵调驱性能试验,研究微纳米颗粒三相泡沫体系特性,应用归一化和权重系数方法,分析三相泡沫体系溶液特性与驱油效果的相关性。结果表明:软体微米颗粒三相泡沫体系的特性参数较好,具有超低界面张力,剖面改善率超过82%,聚驱后可提高采收率超过14%;硬质纳米颗粒三相泡沫体系的特性参数相对较差,但聚驱后仍可提高采收率超过10%;三相泡沫体系泡沫综合指数和运动黏度是驱油效果的主要影响因素,而剪切黏度和界面张力是次要影响因素。

Abstract:
In order to further improve the oil recovery after polymer flooding, a micro-nanoparticle three-phase foam system with self-adaptive plugging and flooding function was constructed considering the reservoir characteristics after polymer flooding. The characteristics of micro-nanoparticle three-phase foam system were studied by viscosity, interface, foam, and plugging and flooding performance experiment. The correlation between solution characteristics and oil displacement effect of three-phase foam system was analyzed by normalization method and weight coefficient method. The results show that the characteristic parameters of the three-phase foam system with soft micro particles are good and it has ultra-low interfacial tension. Its profile improvement rate is more than 82%, and it can enhance oil recovery by more than 14% after polymer flooding. The characteristic parameters of the hard nanoparticles three-phase foam system are relatively poor, but it can still enhance oil recovery by more than 10% after polymer flooding. The foam comprehensive index and kinematic viscosity of three-phase foam system are the main influencing factors of oil displacement effect, while the shear viscosity and interfacial tension are secondary influencing factors.
Key words:  micro and nano particles  three-phase foam system  after polymer flooding  viscosity  profile improvement rate
