Two-dimensional displacement experimental device for simulating different water body multiples and experimental method of two-dimensional displacement experimental device

The invention provides a two-dimensional displacement experimental device for simulating different water body multiples and an experimental method of the two-dimensional displacement experimental device, and belongs to the technical field of petroleum industry. An oil reservoir is simulated through a two-dimensional sand-packed section model, an intermediate container is divided into a water injection part and a gas injection part through an isolation piston, the water injection part is communicated with the two-dimensional sand-packed section model, and the gas injection part is communicated with the two-dimensional sand-packed section model; the gas injection part is communicated with a high-pressure gas pump, so that the pressure of the water body in the water injection part can be increased along with the increase of the gas pressure of the gas injection part under the driving of the high-pressure gas pump, and then different water body multiples are simulated. According to the embodiment of the invention
