Abstract

The invention discloses an artificially resonant wave strengthened oil displacement dynamic simulation experimental device and an experimental method. The experimental device comprises an artificially resonant wave test bed, core grippers fixed on the artificially resonant wave test bed, thermotanks distributed outside the core grippers, an intermediate transitional water-delivery container, an intermediate transitional oil delivery container, a water storage tank, an oil storage tank, and liquid containers connected with liquid outlets of the core grippers. The experimental device comprises the following steps of: 1, performing an unartificially resonant wave dynamic simulation experiment; 2, replacing cores and performing an artificially resonant wave dynamic simulation experiment on the plurality of cores under the artificially resonant wave vibration conditions of different frequency and identical vibration acceleration; and 3, performing data processing. The device and the methodensure rational design, convenience of distribution, use and operation, perfect functions and good simulation effect; and the single-phase and two-phase seepage characteristics of the cores, the saturation of residual oil and the final oil recovery factor can be tested under the conditions of artificially resonance waves and different displacing mediums.
