【摘要】 研究泡沫在多孔介质中生成、运移、传播的微观机理与宏观速度压力之间的部分关系。CT和NMR辅助物理模拟实验能同时测得岩心中流体的微观分布和相应的宏观参数变化,该实验是研究泡沫驱微观机理与宏观控制因素关系的重要方法。深入研究泡沫驱微观机理及微观机理与宏观控制因素之间的关系,是泡沫驱技术从一种有潜力的三次采油技术发展成为一种稳定可控的三次采油技术的关键。更多还原

【Abstract】 This paper studies the micro-mechanisms of foam generation in porous media;summarizes the recent research of foam flooding including microscope generation,migration and propagation;and reveal partial relationships Among microscope generation,migration,propagation and macroscopic pressure or velocity.Investigation of experiment methods shows that CT and NMR assistant experiment can measure the microscope distribution of fluid in porous media and corresponding changes in macro-parameters simultaneously,so that they are important methods to study the relations between microscopic mechanism and macro-parameters.Studying the micro-mechanism in depth and exploring the relation ship between the micro-mechanism and macro-parameters is a key step for foam flooding developing from a potential technique to be a stable and controllable technique.更多还原
