摘要（英）：

The invention discloses a three-dimensional seepage experimental system for 10MPa monitoring of the water-oil displacement process. The three-dimensional seepage experimental system comprises a floor-type drying oven, a large flat plate sand-filling model unit, a pressure monitoring unit, an internal-temperature monitoring unit, a formation pressure unit, an electrode data collecting unit and a displacement unit; the large flat plate sand-filling model unit is arranged in the floor-type drying oven and comprises a bottom plate, a mold cavity, a cover plate, a rack, an overturning mechanism, arotating shaft and a rolling bearing; electrode set units are vertically arranged on the bottom plate; the mold cavity is formed in the bottom plate, the cover plate is arranged on the mold cavity, and the formation pressure unit is arranged on the cover plate; and the mold cavity is provided with a vertical borehole valve set and a horizontal borehole valve set. According to the three-dimensionalseepage experimental system, the formation resistivity change can be simulated, three-dimensional resistance imaging can further be achieved, and the influence of distribution of horizontal wells andvertical wells on the oil production efficiency of a formation reservoir is simulated.
