摘　　要：天然电场选频法在浅层地质勘探尤其是地下水资源勘探应用广泛,而目前运用选频法寻找地下水时仅利用选频法静态信息进行剖面测量,忽略了动态信息对辅助确定井位的作用,为此设计一种密频点的信号采集及动态信息提取方案.在湖南浏阳大围山地质公园内进行寻找基岩裂隙水实践中,与湖南继善高科技有限公司SQ-5型双频激电仪进行对比实验,实验结果表明:2台仪器观测结果吻合良好,并利用动、静态信息成功验证了井位,证明本系统设计的可行性、可靠性,在资源勘察、工程物探,尤其是在寻找地下水资源方面应用前景广阔.As a passive geophysical exploration method,natural electric field frequency selection method is widely used in superficial geological exploration,especially in groundwater exploration.So far,the static information has been used to make profile measurement when the method of frequency selection is applied to search for groundwater,ignoring the effect of dynamic information in determining well location.Therefore,this research designs a dense frequency signal acquisition and dynamic information extraction scheme.A practice of searching bedrock fissure water is made at Daweishan geological park in Liuyang city,Hunan province,compared with SQ-5 dual-frequency induced polarization apparatus produced by Hunan Jishan high-tech Co.,Ltd.The contrast experiment result shows that two instruments observation results agree well,which proves that the design of this system is feasible and reliable,and has a broad application prospect in resource exploration,engineering geophysical exploration,especially in searching groundwater resources.
