Single well-injection and water-suction tracer experiment simulation analysis system

Abstract

The invention relates to a single well-injection and water-suction tracer experiment simulation analysis system. The single well-injection and water-suction tracer experiment simulation analysis system comprises a well body, a geological water-containing layer simulation module, an overflow device, a distilled water box, a tracer box, a sucked liquid storage box, and a background data processing and simulation analysis terminal, wherein a water containing area and a flow stabilizing area, which are communicated with each other, are arranged in the geological water-containing layer simulation module, and are respectively filled with a water-saturated medium and a flow stabilizing medium; the well body and the overflow device are respectively communicated with the water containing area and the flow stabilizing area; a liquid inlet pipe and a liquid outlet pipe are arranged on the well body, and the distilled water box and the tracer box are respectively communicated with the liquid inlet pipe through pipelines; one end, away from the well body, of the liquid outlet pipe is communicated with the sucked liquid storage box; a plurality of layers of liquid concentration sensors are uniformly distributed in the water containing area, and a plurality of liquid concentration sensors are arranged on each layer; the liquid concentration sensors are electrically connected with the background data processing and simulation analysis terminal. The single well-injection and water-suction tracer experiment simulation analysis system has the advantages that the structure is simple, the operation is convenient, and the testing of single well-refilling and water suction tracer experiment can be performed at high accuracy and high frequency.

Description

technical field [0001] The invention relates to a single well injection-pumping tracing experiment simulation analysis system. Background technique [0002] Calculating the thermal and hydrodynamic diffusion coefficients of aquifers is an important research content in the scientific research of groundwater environment, and the existing test instruments and methods have great limitations. At present, most of the one-dimensional soil column experiments are used to test the solute transport status of radial flow, or other more complicated experiments are used to study the solute transport status of radial flow, and the cost of the research process is relatively high. And there is no systematic single-well pumping and injection experimental teaching device at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a single well injection-pumping tracing experiment simulation analysis system, which effectively overc...
