摘      要：The present research is to experimentally study the joint effects of external pressure and vibratory excitations of low frequency on oil slug mobilization and flow in a capillary *** and after the oil slug mobilization,the flow phenomena and pressure drop variation across the model are *** distance travelled by the oil slug subjected to various external pressure and vibratory excitations are also *** experimental results obtained indicate that the external vibratory excitation acting on the model has positive effect on the flow and mobilization of the oil slug in the *** is found in the research,with the application of the excitation,the contact angle between the oil slug and tube-wall is changed;the maximum pressure required to mobilize the oil slug is reduced accordingly;and the oil slug travel distance is increased in comparing with that without external *** research contributes to the comprehension of improved liquid mobilization in porous media under the application of external *** finding of the research is significant for studying the two-phase liquid flow in porous media subjected to external excitations and provides insights for Enhanced Oil Recovery with waterflooding and vibratory stimulations.
