摘　　要：高密度电法测点密度高,信息量大,在进行地表地质结构调查、探测岩溶发育等方面得到了广泛的应用。本文介绍了在涪陵焦石坝地区采用高密度电法对钻井平台的地表地质结构进行调查的方法,分析了钻井平台的安全性,并用实际钻探验证了地表地质调查的结果,取得了良好的地质效果。并对高密度电法在类似灰岩区的油气钻井平台选址应用中的可行性进行了评估。High density resistivity method has high density, and it is informative, which is widely applied to the surface geographical structure survey and karst development. In this paper, High Density Resistivity Method for well platform in Jiaoshi dam region is intro- duced, and the safety of drilling platform is analyzed. The results have been proved by the actual drilling. The feasibility of this prospecting method in karst region for the selection site of drilling platform is evaluated.
