【摘要】 泡沫驱是最有发展前途的三次采油方法之一,它既能显著地提高波及系数,又能提高驱油效率。与常规泡沫驱油相比,自生泡沫驱最大的优越性是提供了气源,它不用专门的供气设备和专门的注气设备。因而该技术施工简便,经济高效,在油田开发中具有很大的推广价值和应用前景。本文通过微观模型实验着重研究了自生CO2泡沫复合体系的驱油机理,为该技术的进一步研究提供了理论依据。更多还原

【Abstract】 Foam flooding is one of the most potential EOR methods, which can obviously enhance sweep efficiency and displacement efficiency.Compared with conventional foam flooding,the advantage of self-generating foam flooding provides gas source without special supply equipment and special injector equipment.Thus,this technique includes several characteristics such as simple operation,convenient,economy and high effective,which has significant popularizing value and application prospect.In this paper,displacing oil mechanism of self-generating CO2 foam multi-system by using micro-model tests is emphasized to study,providing theoretical foundation for further study.更多还原
