Research status and prospect of vibration stimulation technology

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.
