微波采油技术研究现状及展望

微波采油是一种利用电磁能高效转化的新型采油技术,在非常规油气绿色开发领域具有广阔的应用前景。结合大量文献调研,通过对微波采油进展的探讨,分析出微波采油的四种提采机理及应用现状。研究认为:微波采油的提采机理包括作用于原油的热效应和非热效应以及对储层产生影响的造缝作用和润湿反转作用;微波在采油生产中常用于进行原油分离、破乳、脱蜡、解堵等;在对稠油等非常规油藏进行开发时,以蒸汽为主的单一热采措施增产效果有限,微波辅助蒸汽热采以及纳米催化剂辅助微波采油是未来微波采油技术发展的主要方向。

Research Status and Prospects of Microwave Enhanced Oil Recovery

Microwave enhanced oil recovery is a new type of oil recovery technology that utilizes electromagnetic energy for efficient conversion. It has broad application prospects in the development of unconventional oil and gas. Based on this, combined with a large number of literature research, through the discussion of the progress of microwave enhanced oil recovery, the four extraction mechanisms and application status of microwave enhanced oil recovery are analyzed. According to the research, the production mechanism of microwave enhanced oil recovery includes the thermal effect and non-thermal effect acting on crude oil; the effect of seam formation and wetting reversal acting on the reservoir. Microwave is often used in oil production for crude oil separation, demulsification, dewaxing, plugging and other methods. In the development of unconventional reservoirs such as heavy oil, the single thermal recovery method based on steam has limited effect on increasing production. Microwave-assisted steam thermal recovery and nanocatalyst-assisted microwave oil recovery are the main directions for the development of microwave enhanced oil recovery technology in the future.
