Abstract
A device for testing the three-phase saturation of oil, gas and water in a high-temperature and high-pressure planar model includes a displacement pump, a confining pressure pump, a back pressure pump, containers, a planar model system, a data acquisition system, a back pressure valve and an oil-gas separator. The planar model system includes a planar model, an autoclave body, a heating temperature-controlling system, a Y-axis direction stepping motor, a X-axis direction stepping motor and an acoustoelectric detector. A method for testing the three-phase saturation of oil, gas and water by using the device includes calibrating three-phase saturation of oil, gas and water to a rock core, preparing a formation water sample and a crude sample, regaining the original formation conditions of the planar model, simulating the depletion or displacement process of oil reservoirs, performing linear ultrasonic-and-resistivity-scanning test on planar model, determining the three-phase saturation distribution of oil, gas and water.
