Abstract
Abstract
Nuclear magnetic resonance (NMR) is the only geophysical method that can directly detect groundwater. However, the response signal collected by nuclear magnetic resonance method is very weak, and it is difficult to detect reliable results by conventional ground nuclear magnetic resonance when the water-bearing anomaly is located deeper underground. In order to increase the detection depth, the surface-to-underground nuclear magnetic resonance device received in the ground launch roadway can be used. In this paper, the basic principle and working method of surface-to-underground NMR are introduced. The three-dimensional numerical simulation of different water-bearing structures and different device forms is carried out, and the response law and advantage range of surface-to-underground NMR to underground water are summarized.
