A detection device includes a chamber, a top of the chamber is cover with a chamber cover, and a side wall of the chamber is provided with a port D. The chamber is provided with a first waterproof layer and a second waterproof layer, and a water storage layer is disposed between the first waterproof layer and the second waterproof layer. A water supply pipe is disposed in the water storage layer, and the water supply pipe includes a port Dand a port D. An end second pipe is connected to the port D, and another end of the second pipe facing away from the first pipe is provided with a port D. An online detection component and a vacuum extraction system are disposed outside the chamber. The detection device can quantitatively simulate and detect the process of rare gas migration and accumulation under formation water conditions.
