Abstract: In order to provide a way to expand clean heating energy and promote the utilization scale of groundwater heat pump system, the authors focused on the widespread saline water body in the study area, based on the stratigraphic characteristics of Quaternary strata. The distribution patterns of sand and saline water body of Quaternary were analyzed, and the pumping tests and reinjection hydrogeology tests from four previous shallowing geothermal energy exploration projects were summarized. The results show that the yield of a single well is 320-475 m³/d in saline water layers, with the unit yield of 12.76-28.3 m³/(d·m). And the natural reinjection rate is 30-56 m³/d, with the unit reinjection of 5.85-17.5 m³/(d·m). The total allowable heating floor area is 3 481.02 m² for one well, which could satisfy the heat load of 35 rural houses in winter. The groundwater heat pump system is preferable in the shallow geothermal development in the study area, while the scatter distributed ground-coupled heat pump system is optional for single rural building with less energy need for space heating/cooling.
