Quick identification of weathering crust of carbonate rock in buried hill while drilling

Quick identification of weathering crust of carbonate rock while drilling plays an important part in buried hill exploration,while the formation lithology is hard to identify by traditional logging method.Based on the analysis of formation elements characteristics,elements combination characteristics,elements logging technology principles and processes,in combination with field application,laboratory analysis,geological analysis and drilling engineering characteristics,quick identification of weathering crust of carbonate rock can be realized.The field application results indicate element logging technology can provide scientific guidance for the quick identification and be of good application prospects in exploration and production of buried hill.
