The geological condition analysis of pilot hole drilling for curtain grouting of reservoir engineering is an important technical link of curtain grouting of concealed engineering with high seepage control process requirements in reservoir engineering,which is of great engineering significance to the quality of curtain grouting process of reservoir engineering.Therefore,the typical cases of geological condition analysis of pilot hole drillingfor curtain grouting in Bancong Reservoir project are analyzed and studied.The results show that to familiarize with the project overview,one needs to understand the geological status of the Bancong Reservoir dam site area;And focus on analyzing the geological conditions of pilot hole drilling from two aspects:the purpose and task of the pilot hole,the geological conditions of the pilot hole drilling(including the geological conditions of drilling W-I-1,W-I-9,W-I-193,W-I-201,and the judgment results of the geological conditions of the pilot hole drilling).
