Abstract
The present disclosure relates to a groundwater circulation well group and a circulation mode control method therefor. The groundwater circulation well group includes at least two multi-filter-layer groundwater circulation wells, multiple pumping/injection assemblies, and a control module. The at least two multi-filter-layer groundwater circulation wells are arranged in order along a groundwater flow direction. A wellbore of each multi-filter-layer groundwater circulation well is separated by at least two first packers to form three pumping/injection sections, and each pumping/injection section is internally provided with at least one pumping/injection assembly for water pumping/injection. The water pumping and/or water injection of the pumping/injection assembly is controlled by the control module. A pipe wall of each pumping/injection section is provided with a perforated water pumping/injection screen section.
