The technical problems of inaccurate aquifer distribution information detected by the detection method in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of disaster water source detection, in particular to a groundwater nuclear magnetic resonance detection method, system and electronic equipment. Background technique [0002] Surface nuclear magnetic resonance (SNMR) has been used in groundwater detection for nearly 40 years. Because of its property of directly detecting groundwater, this method has been widely used in hydrogeology and engineering geology. [0003] The groundwater detection method in the prior art generally adopts the above-mentioned ground nuclear magnetic resonance method, which adopts the mode of transmitting and receiving co-circles, the transmitting coil and the receiving coil are all located on the ground, and the electromagnetic field propagates from the transmitting coil to the aquifer to excite the nuclear magnetic resonance phenomenon. The energy released by the relaxation of hydrogen nuclei in water is transmitted from the aquife...
