摘　　要：目前"井孔-含水层"系统处理的三种主要方法:基于线汇理论的井孔模拟、高渗透系数法和渗流-管流耦合模型,评述了各种方法的优缺点,重点指出了传统线源(汇)法理论上的缺陷及实际应用中的局限性。概括了MODFLOW,TOUGH2,FEFLOW等地下水数值模拟软件对井孔含水层模拟的方法;应加强井周小尺度水流水质的精细研究,并研究井周水流运动对水质的作用,以及对大尺度地下水模拟的影响。The necessities and scientific background of research on a well-aquifer system is briefly introduced in this article,and the main problems in accurately simulating the small-scale well flow are also point out.The focus of this paper is mainly on the three basic methods of dealing with a ＂well-aquifer＂ system： line source（sink） method,High KV in wellbore and seepage-pipe flow model.The basic theory and disadvantages and advantages of these methods are summarized.In this paper,we also analyze several practical cases of three extensively used groundwater numerical simulation software（MODFLOW,TOUGH2 and FEFLOW） in simulating a well-aquifer system.The following aspects should be further studied： refined research of groundwater flow in and around a wellbore,the influences of ＂well-aquifer＂ flow system on groundwater quality,and the positions of a ＂well-aquifer＂ system on a large-scale groundwater system.
