  • Device and method for measuring flow velocity and flow direction and geological parameters of groundwater through cross holes of deep wells
    Patent number: 11480050
    Abstract: A device for measuring a flow velocity and a flow direction and geological parameters of groundwater through cross holes of deep wells includes detectors and a device for throwing the tracer source. A method includes measuring a correspondence between a conductivity and a concentration of a tracer solution at different temperatures in a laboratory; selecting at least two boreholes; selecting a target aquifer section; placing the detectors in the target aquifer section in the hole to test a conductivity background value and a temperature value; using the device for throwing the tracer source to place the tracer solution in the hole for throwing the tracer source, and using the detectors to measure a water conductivity and temperature in a detection hole, to obtain a distribution curve of a tracer solution solubility with time; performing cross-test, and calculating the seepage flow velocity and flow direction of groundwater in the hole.
