【Abstract】 Artificial Vibration Oil Production(AVOP) is a new and prospe ctive met hod for enhanced oil recovery. A new system for artificial vibrating simulation was designed and effect of artificial vibration on core permeability, oil recove ry under different stage of water flooding was studied. Experiments show that ac tion of artificial vibration can improve the permeability of cores and oil recov ery, 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 pa rameters got in the experiments is almost identical to the parameters used in th e field tests.更多还原
