Compared with a prior method with a single capacitor included, the superposition time of every time is shortened, the working time of each pulse moment is shortened, the charging and discharging time is effectively shortened, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of geophysical exploration equipment for detecting water-containing bodies by using nuclear magnetic resonance, and in particular relates to a fast charging and discharging power supply device for a nuclear magnetic resonance water finding instrument. Background technique [0002] Compared with the drilling method, the MRS method has the advantages of low cost, non-destructive and high efficiency. Compared with other geophysical methods, MRS is a geophysical prospecting method for directly exploring groundwater. However, the measurement time for each test point generally takes more than one and a half hours. The impact of the test site on the environment, in areas with severe noise interference, electromagnetic noise interference is strong, and the number of superimpositions will increase accordingly, and the measurement time may be longer. This will reduce the efficiency of the MRS method and affect the promotion of ...
