The invention provides a foam property measuring device for oil extraction. The device comprises a shaft simulation system for simulating movement of foam in a shaft, a foam injection system for injecting the foam into the shaft simulation system, and a foam measuring system for measuring the foam properties. The shaft simulation system comprises a vertical pipeline, a porous medium and a heating sleeve, multiple measuring points are arranged on the vertical pipeline at intervals, each measuring point is connected to a foam measuring container of the foam measuring system through a porous medium container, and the heating sleeve is arranged outside the foam measuring container. By means of the device, the foam is injected into different oil layers in a simulated mode through the shaft simulation system, and the temperature difference between the oil layers is simulated through the heating sleeve; the foam measuring system measures the properties of the foam for simulating different temperatures and different oil layer conditions and foam shunt volumes, liquid shunt volumes and gas shunt volumes corresponding to all the simulated oil layers; a computer is adopted for automatically controlling the device, the experimental process is safe and reliable, and the labor cost is reduced.
