The newly developed Enhanced Oil Recovery technology implementing vibration and seismic stimulations relies on mobilization of oil trapped in pores of porous media of reservoir. This research indents to investigate the conditions for dynamically mobilizing an oil slug trapped in capillary with controlled vibration. An idealized physical model is established, on which series of experimental tests are performed for determining the conditions. Initiation of the mobilization and the effects of vibration frequency and duration of vibration on the mobilization are analyzed. The results of the research are significant for reveal the mechanism of Enhanced Oil Recovery technology with vibro-seismic stimulation.
