通过物探勘查并结合水文地质资料分析,研究了广西隆安县岩溶石山区断裂带、溶洞、岩溶管道三种储水构造的地质-地球物理模型及其电性响应特征。受构造控制或侵蚀基准面变化的影响,广西隆安岩溶石山区形成多层溶洞及岩溶管道系统,地下水主要赋存于溶洞、管道和构造裂隙中。地球物理上,断裂带及多层洞道系统均表现为纵向低阻条带的电性特征,但储水构造充填物或是水或是泥,难以用电阻率参数加以区分。为提高解译精度,结合工作区的水文地质条件,对物探资料进行细致入微的分析,并在勘察工作中采用在高阻中找低阻、低阻中找高阻的找水定井方法,基本避开了泥质充填的难题,提高了成井率。
Through geophysical exploration and hydrogeological data analysis, the geophysical-geophysical models and their electrical response characteristics of three water-storage structures in the karst rock mountain area of Long’an County, Guangxi Province are studied. Due to the influence of tectonic control or erosion datum, multi-layer karst and karst pipe systems are formed in the Karst area of Long’an, Guangxi. Groundwater mainly occurs in karst caves, pipelines and structural fractures. Geophysically, fault zones and multi-layered tunnel systems are all characterized by vertical electrical resistivity bands. However, it is difficult to distinguish reservoir resistivity parameters from water-filled structures or mud. In order to improve the accuracy of interpretation, combined with the hydrogeological conditions in the work area, the geophysical data are analyzed numerically and in the survey, the method of finding water and setting well to find low resistance and high resistance in high resistance is adopted. Basic to avoid the problem of muddy filling, improve the rate of completion.
