1981年以来,作者们用地质与物探紧密结合的激发极化井字型剖面法,先后在河南省灵宝县黄土塬区,新安县浅山丘陵区和修武县平原区等不同地貌单元、不同时代地层岩性分布区,开展了大面积(1933·8km2)的激发极化法普查地下水工做。本文概略地介绍了大面积普查的基本工作方法,用大量的实测资料勾绘ρs、D、 η 、J等值图,并据此作出相应的地质推断图,其中包括灵宝县黄土塬区(灵—陕断陷盆地)深埋下更新统(Qt)河湖相砂卵石承压含水层组、新安县浅山丘陵区中的“南岗地下水库”和修武县平原区中的沁河古河道。经打井验证,均取得了好的地质效果与经济效益,含水层吻合率在95%以上。
Since 1981, the authors have used geophysical and geophysical methods to stimulate polarization well-shaped cross-section method, successively in Loess Plateau area of Lingbao County of Henan Province, Xin’an County shallow hill and Xiuwu plain area and other different landform units, Epoch lithology of the distribution area, launched a large area (1933 · 8km2) excitation polarization census groundwater work. This paper briefly introduces the basic working methods of large-scale census, and plots the ρs, D, η, J contour maps with a large amount of measured data and accordingly makes the corresponding geological inference maps, including the Loess Plateau Ling-Shan Faulted Basin), the Qt facies-gravel cobblestone aquifer, the “Nangang reservoir” in the shallow hills in Xin’an County and the ancient Qinhe River in the Xiuhe plain . After drilling well validation, have achieved good geological results and economic benefits, aquifer coincidence rate of 95%.
