A method and a device for performing simulating profile control to a heterogeneous reservoir in a laboratory. The invention mainly aims to solve a problem that there is no effective method and device for achieving the simulating profile control to the heterogeneous reservoir in the laboratory in the prior art. The device includes a heterogeneous core model, an injection metering apparatus and an extraction collection apparatus. The heterogeneous core model is composed of an inlet outer-buckle fixer, a core main body holder, and an outlet outer-buckle fixer. The method includes following steps: (1) when relative data is acquired by the device, calculating single-layer practical injection amount V and fluid channeling amount V<ci> at each layer; (2) when the fluid channeling rate at the highest layer reaches a diversion limit in a practical mine field, changing a profile control liquid and injecting the profile control liquid through a pump, and stopping the pump until the accumulated injection amount at a core injection end reaches the injection amount required to be simulated in the practical mine field; (3) changing the profile control liquid into the original injection liquid again, starting the pump for simulating a subsequent displacement process to respectively obtain fluid channeling rate C at each layer, thereby achieving a profile control quantitative effect after injection of the profile control liquid.
