摘要
Using the unsteady flow large diameter well method,predicted and evaluated on drawdown cone of groundwater extraction,which with different planned yield and different recovery time,of Da’an the second water source that was multiple layers superposed water-bearing structure.Put forward preventive measures for depression cone irreversible,unreasonable interference between wells,and adverse impact on groundwater environment of oil exploitation.Lay the foundation for the sustainable utilization of groundwater resources,balance between exploitation and supply resources and environment coordinated development,and broaden the rational development and utilization.
