Abstract: The present invention provides a device and a method for measuring overburden of injected gas in cyclic gas injection development of condensate gas reservoir. The device comprises sand packed model and temperature control system. The temperature control system is nested outside the sand packed model. The sand packed model comprises sand pack cell, four gas inlets, four gas outlets, bracket, direction control component, rotating shaft, upper cover, lower cover, fixing bolts, two top pressuring inlets, pressure transmission rods, pressure transfer piston and multiple gas sampling ports. The sand pack cell can be filled with quartz sand of different particle size and composition, and the angle of the whole device is adjusted by the direction control component.
