摘 要: | 通过在广西来宾岩溶干旱区的找水实践 ,将峰林平原区定井技术主要归纳为地质构造方法、蓄水构造方法和综合物探方法。地质构造方法可了解断裂富水带的分布规律 ,以指导寻找各种蓄水构造 ;利用蓄水构造方法归纳出该区 7类岩溶蓄水构造 ,并确定其三维几何形状和内部介质特征 ,为水文物探解释提供地质依据 ;水文物探方法可提供富水地质体的定量、半定量信息。文章认为地质—物探—钻探工作密切配合和交流 ,是提高成井率的保证。

Abstract: | The borehole location techniques were summarized in this article, according to the experiences of groundwater exploration in peak forest-plain area of Laibin County. There are many methods for borehole location, such as geological structure analysis, groundwater-storage structures analysis,hydro-geophysical prospecting, nuclear techniques, et al. The distributed characteristics of fault water-bearing belts and the general position of others groundwater-storage structures can be given for the first time by geological structure analysis. Seven groups of water-bearing structures are given and the characterization of their 3-dimensional geometry and void space texture are summarized, which may serve as geological basis for planning geophysical prospecting work and interpretation of its results. The quantitative & semi-quantitative data of the water-bearing target can be given by hydro-geophysical prospecting. We suggest that multi-methods such as hydrogeology, geophysical prospecting, drilling should be used synthesizely in borehole location. |
