Full 3D simulation visual displacement simulation experiment system for fracture-vuggy reservoirs

The invention relates to a fully-three-dimensional simulated visualized displacement simulation experiment system of a fractured-vuggy oil reservoir. The fully-three-dimensional simulated visualized displacement simulation experiment system comprises trough, fractured-vuggy model, water injection, air injection, image acquisition and data acquisition simulation unit, a simulation oil groove and a three-phase separator. The trough simulation unit comprises a cubic trough, a glass pipe and a shaft. The fractured-vuggy model simulation unit comprises a cavern model and a crack model. The water injection simulation unit comprises a water injection tank and a water pump. The air injection simulation unit comprises an air compressor, an air storage tank, an emptying valve, a water draining filter and an air dryer. A particle forming test module of the image acquisition simulation unit is arranged on a sliding rod and installed on a support through the sliding rod. A pressure variator of the data acquisition simulation unit is installed at the connecting position of the shaft and the fractured-vuggy model simulation unit. The output end of the three-phase separator is respectively connected with the simulation oil groove and the water injection tank, and the input end of the three-phase separator is connected with the shaft. The fully-three-dimensional simulated visualized displacement simulation experiment system of the fractured-vuggy oil reservoir is simple and reasonable in structural design and capable of timely, intuitively and accurately monitoring a flow field and pressure change in a stratum.
