Application of comprehensive geophysical exploration technology to groundwater exploration in carbonate rock area
The southwest of China is the main distribution area of carbonate rocks,and the southwest of China is seriously short of water and inconvenient to transport.Therefore,it is of great significance to explore the exploration technology of groundwater in carbonate rocks.Geophysical exploration technology is one of the important means in groundwater exploration at present,but a single geophysical exploration means has multiple solutions.Therefore,this paper studies the application of comprehensive geophysical exploration methods,and various methods verify each other and learn from each other.Taking the typical carbonate rock area of Chaohu Lake in Anhui province as the test area,the known geological,magnetic and electrical data in the area were re-analyzed and interpreted,and the possible water storage structure location was defined.Then,the structure occurrence and burial depth were determined by audio magnetotelluric method.Finally,the micro-motion detection technology was used to determine the precise drilling.The overall research work is less,the cost is low,the effect is remarka-ble,and it is of great significance to popularize.
