振动采油技术的研究现状及展望

Research status and prospect of vibration stimulation technology

介绍了振动采油的起源、国内外研究现状、振动采油的机理以及目前振动采油技术的不足和发展趋势,指出振动采油的关键在于保障振源振力能有效传入油层能量,确定与油层匹配的振动频率可控的多点震源,加强振动场、渗流场、固体介质场三场耦合的基础理论研究。振动采油技术可望成为聚合物驱后提高采收率的有效技术。

With the development of physical oil recovery,vibra- tion stimulation technology has become a new important way for oil production.In this paper,its origin,research status home and abroad,mechanism,shortcomings and development trend have been discussed.The key of the technology lies in how to guarantee the vibration energy effectively received by formation,determine multi-point sources controlled by vibration frequency which matches with oil layers,and strengthen the coupling analysis of vi- bration field,seepage slow field and solid medium field. The vibration stimulation technology is expected to be an effective way to enhance recovery after polymer flooding.
