【摘要】 目前物探技术地下水勘探主要使用直流电法探测,但在地表高阻层存在时,高阻层对直流屏蔽使勘探深度大大减小,瞬变电磁在勘探深部地下水时横向分辨率降低及深度对应都存在问题,随着地震勘探技术的不断深入及提高,地震勘探技术逐渐应用于该领域,用以划分地层结构和确定岩性孔隙度。该文应用地震勘探对构造裂隙探测优势及亮点技术、水平反射技术在干旱地区寻找深部地下水,通过实际验证取得良好效果。更多还原

【Abstract】 the geophysical prospecting groundwater exploration mainly use DC electrical survey,but exist in the surface layer of high resistance,high resistance layer on the DC shield exploration depth is greatly reduced,the transient electromagnetic decrease the lateral resolution in the exploration of deep groundwater and the depth corresponding problems,along with the deepening of seismic exploration technology and improve,seismic exploration technology has been gradually applied in the field,in order to partition structure of stratum and lithology porosity determination.In that paper,application of seismic exploration of structural fissure detection advantage and bright spot technology,horizontal reflection technique for deep groundwater in arid regions,and obtained good effect through practical verification.更多还原
