#$%^&*AU2015285966B220170525.pdf#####ABSTRACT 5 The present invention provides a physical simulation experiment device of fracture-cavity carbonate reservoir hydrocarbon charge. The experiment device comprises a fracture-cavity model, an experiment stand with windows, a wall rock and a camera monitoring system; the fracture-cavity model comprises simulation caves in different sizes 10 and simulation fractures in different sizes; the simulation caves are connected to one another via the simulation fractures; the fracture-cavity model is arranged inside the experiment stand with windows, and the simulation caves of at least one side of the fracture-cavity model are visual through the windows of the experiment stand; a surrounding of the wall rock is arranged around the fracture-cavity model to simulate a 15 formation of fracture-cavity carbonate reservoir; the camera monitoring system is used for measuring and adjusting changes in flow rate and pressure in a charge process, and recording an image of fracture and cave in the charge process displayed in the windows. The present invention further provides a physical simulation method of fracture-cavity carbonate reservoir hydrocarbon charge, which uses the above-mentioned experiment 20 device. The present invention can obtain regularities of distribution of oil, gas and water through parameters such as karsts, fractures, density of cruel oil, and oil, gas and water distribution and the like. 25 301/15 Fig: 23 4 5 131 F1 FIG 1
