The invention discloses a hydraulic power pulse
oil displacement experimental facility and an experimental method thereof. The experimental facility comprises a core clamping device, an annular pressure supply device, a hydraulic power
pulse wave generating device, a
water storage tank and an
oil storage tank which are connected with the liquid inlet of the core clamping device by virtue of a water pipeline and an oil pipeline as well as a liquid container which is connected with the liquid outlet of the core clamping device; wherein the water pipeline and the oil pipeline are all provided with an intermediate container, a pumping device used for generating
high pressure liquid flow and an
energy storage tank. The experimental method includes the following steps: firstly, oil displacementexperiment is carried out under the condition that no hydraulic power pulse is added; secondly,
oil displacement experiment is carried out while frequency and amplitude hydraulic power
pulse wave of core are replaced, and meanwhile hydraulic power pulse auxiliary chemical
oil displacement experiment is completed; thirdly,
data processing is carried out. The invention has reasonable design, mounting convenience, simple operation and good
simulation effect, can improve efficiency of oil displacement by water and
crude oil recovery ratio, and experiment of hydraulic
pulse wave oil displacement and hydraulic pulse wave auxiliary reservoir core oil displacement by water can be realized.
