Abstract: Artificial Vibration Oil Production(AVOP) is a new and prospective method for enhanced oil recovery.A new system for artificial vibrating simulation was designed and effect of artificial vibration on core permeability,oil recovery under different stage of water flooding was studied.Experiments show that action of artificial vibration can improve the permeability of cores and oil recovery,while decrease the water cut at the stage of high water-cut.The results of oil recovery increment were related to the vibrating parameters.The optimum parameters got in the experiments is almost identical to the parameters used in the field tests.
