The utility model provides a hydrate reservoir visualized gravel packing simulation experiment system which comprises a solid-liquid supply system, a reaction kettle, a lifting system and a liquid storage tank, and the top end of the solid-liquid supply system is connected with the solid-liquid supply system through a pipeline; the reaction kettle is used for simulating gravel packing and stratum damage conditions at different axial positions of a shaft; the reaction kettle is fixed on the lifting system, and the lifting system is suitable for controlling the inclination angle of the reaction kettle so as to carry out gravel packing experiments under different inclination angles; the liquid storage tank is communicated with the side wall of the reaction kettle through the pipeline, and the liquid storage tank is used for storing gravel-carrying liquid returned from the reaction kettle. According to the utility model, gravel packing experiments under different shaft inclination angle conditions can be simulate
