The invention discloses an indoor evaluation device for a shaft dynamic liquid level monitor. The indoor evaluation device comprises a well drilling ground simulation system, a shaft simulation system and a shaft environment simulation system. The well drilling ground simulation system comprises a liquid level monitor. The shaft simulation system comprises a shaft simulation pipeline connected with the liquid level monitor and a plurality of valves arranged at preset positions in the shaft simulation pipeline. Each of the valves can be adjusted between an open state and a closed state, and the valves in the closed state can reflect infrasonic waves emitted by the liquid level monitor and are used for simulating the dynamic liquid level position of a shaft. The wellbore environment simulation system comprises a wellbore environment simulation component which is connected in the wellbore simulation pipeline and used for changing the environment in the wellbore simulation pipeline. The indoor evaluation device f
