基于综合物探的激电二次时差法在含碳质泥质灰岩区找水探测实践与探讨
Practice and discussion of the induced polarization secondary time difference method in water exploration of carbonaceous argillaceous limestone areas based on integrated geophysical exploration
摘要
Abstract
To address the applicability challenges of geophysical water exploration methods in the Carboniferous Huangjin formation of carbonaceous-argillaceous limestone characterized by uneven development of dissolution fissure,complex hydraulic connectivity of argillaceous shale interlayers,concealed groundwater occurrence conditions,scant water resources,and improve the success rate of water well drilling,This paper adopts high-density resistivity and Audio-frequency Magnetotelluric Sounding(AMT)methods to detect low-resistivity anomalies in an area of Shaoshui town,Guilin.By applying the induced polarization(IP)secondary time difference method to analyze and delineate water-induced anomalies within these low-resistivity zones.the spatial distribution and occurrence characteristics of groundwater were identified.Results indicate that the AB/2 positions characterized by low-resistivity anomalies,positive induced polarization secondary time difference values with good continuity correspond to the actual aquifer locations.Meanwhile,areas with single-point values or values below 50 ms and poor continuity exhibit low water-bearing capacity.关键词
