The invention provides a gas production column for monitoring gas injection driving oil well field aeration zone soil carbon dioxide flux. The gas production column comprises a soil moisture sensor, atemperature sensor, a dynamic gas production box, a depth location rod, a blowoff valve, a gas collecting hood, a perforated plate, a pressure balance valve and a recording module, wherein the upperend of the dynamic gas production box is connected with the depth location rod, the gas collecting hood and the perforated plate are arranged at the lower part of the inner side of the dynamic gas production box, the perforated plate is arranged under the gas collecting hood, the soil moisture sensor, the temperature sensor and the pressure balance valve are all arranged at the lower part of the gas collecting hood, the upper end of the pressure balance valve is connected with the blowoff valve through a pipeline, and the soil moisture sensor and the temperature sensor are connected with the recording module through cables. As the pressure balance valve is arranged in the dynamic gas production box, negative pressure generation in a gas collecting process for measuring carbon dioxide fluxis avoided, and monitoring accuracy is improved; furthermore, temperature and soil moisture information of a target point position can be synchronously measured.
