摘要
物理模型是研究黏性指进现象的重要方法之一,但由于室内实验条件的限制,当前黏性指进物模装置主要存在模拟的真实性不足、指进现象可视化困难等问题,装置的耐温耐压也不尽如人意。依据相似准则、参考间接成像,研发出既可以获取黏性指进界面,跟踪流体流动状态,又能保证模拟的真实性和可靠性的装置是未来研究的重点,同时找到合适的分析方法和分析指标,这将对油田注水、注气和酸压等工程实际具有重大意义。
Physical model is one of the important methods to study viscous fingering phenomenon.However,due to the limitation of laboratory experimental conditions,the current viscous fingering device has some problems such as insufficient authenticity of simulation,difficult visualization of fingering phenomenon,unsatisfactory temperature and pressure resistance,etc.According to the similarity criterion and reference indirect imaging,it is the focus of the future research to develop a device which can not only obtain the viscous finger interface,track the fluid flow state,but also ensure the authenticity and reliability of simulation.At the same time,the appropriate analysis method and analysis index can be found out,which is of great significance to the engineering practice of water injection,gas injection and acid fracturing.
