云南省岩溶水地球物理探测实践
In recent years, the main methods adopted for karst water prospecting in Yunnan province have been resistivity sounding, nuclear magnetic resonance, resistivity imaging, etc.. The achievements and problems of the applications of these methods have been discribed in the paper, with valuable experiences summed up and technical parameters specified. And even more important, an optimized procedure for the karst water prospecting has been proposed. That is to adopt resistivity sounding to quickly cover a large area first to outline preliminarily watery sectors, and lay-out boreholes based on the sounding and geological data; then perform nuclear magnetic resonance soundings around each planned borehole location to map out water abundance of an area unit circled by the antenna frame; finally carry out densely-spaced resistivity soundings within the most prospective units to locate water-bearing bodies. The procedure has made the probability of success of drilling greatly increased.
