摘要

In view of deep drilling platform in Guizhou encounters a large karst areas and large-scale mud emerges from the drilling,bring great difficulties to the drilling.We layout of two survey lines which perpendicular to each other on the ground to carry out AMT exploration.Based on the 2-D NLCG inversion results of AMT,Identified the spatial distribution characteristics of the underground karst,provide a basic geophysical data for re-selecting the location to drilling.Verified by drilling,AMT method exploration results achieved good results.
