Establishing a rational model of groundwater exploitation and utilization is very important for the construction of an energy base and mitigating its urgent shortage of water resources. Based on an analysis of the conditions of groundwater in the Nanliang-Baibao area, a 3D groundwater flow conceptual model and a numerical model are constructed in a selected typical area. By modeling the shape of the drawdown cone using different exploitation scenarios with different single well yields and different well spacings, the manner of rational groundwater exploitation and utilization is studied. The analytical results indicate that the groundwater pumping wells should be laid out in the main river valley and that the linear well array should be used to intercept the river discharge as the yield. It is advisable that the linear pumping rate should not exeed (0.02-0.03)×104 m3/(d·km).
