The utility model belongs to the technical field of oil exploitation. The on-site gas collection device for the CO2 flooding production well comprises a glass joint and a glass sampling pipe which arecommunicated with each other and are connected in a sealed mode, the glass sampling pipe comprises a gas inlet channel, a gas storage cavity and a gas outlet channel which are sequentially connectedfrom top to bottom, and gas control switches are arranged on the gas inlet channel and the gas outlet channel. For H2S gas in oil well produced gas, the device avoids the problem that a common commercial gas sampling bag adsorbs H2S, samples are collected more accurately, stably and reliably, data reference is provided for indoor tests to discover gas channeling in time, and then safe operation ofproduction is guaranteed. Meanwhile, the operation is convenient, the flow is simple, and the gas sample of the oilfield production well can be conveniently collected. 本实用新型属于石油开采技术领域，提供了一种用于CO驱采出井气体现场采集装置，包括相通且密封连接的玻璃接头和玻璃采样管
