AI Technical Summary
Existing technologies struggle to accurately identify the source and location of salt release from weakly permeable layers in brine wells, leading to inaccurate brine resource assessments. Furthermore, existing monitoring devices exhibit poor stability during pumping operations and are prone to electromotive force interference, making in-situ stratified monitoring impossible.
An electrical cable is laid vertically along the well wall in the pumping well, and multiple electrodes are set up and tightly attached to the well wall by an inflatable fixing mechanism to collect natural potential data. The dominant layer for salt release in the weak permeable layer is identified by the potential anomaly, and the salt release rate is inverted by combining the diffusion-adsorption potential theory.
It enables in-situ and stratified dynamic monitoring of salt release from different layers in brine wells, accurately locates the dominant release layers, reduces construction costs, avoids liquid mixing and pollution, and provides a precise basis for optimizing mining schemes.
