  • Tracer diffusion device, system for tracing development of water conducting fracture zone and relataed method
    Patent number: 12091971
    Abstract: A tracer diffusion device includes: a first container, a second container, a drilling pipe, a unidirectional driving device, and a bidirectional driving device. The first container holds a first fluid containing a tracer. The second container holds a second fluid. A first end of the drilling pipe is connected to the first container; a second end of the drilling pipe is extended into a borehole and equipped with a first sealing capsule and a second sealing capsule. A plurality of through holes are arranged on the drilling pipe between the first sealing capsule and the second sealing capsule. The unidirectional driving device is arranged on the drilling pipe, for injecting the first fluid from the first container into the borehole between the first sealing capsule and the second sealing capsule. The bidirectional driving device is arranged between the second container and the first sealing capsule.
