The water level and water temperature of Beilun and Cixi wells from Ningbo hydrogeological monitoring well network were observed for the experimental study. The pressure efficiency of water level, the rainfall load effect, and the tidal factor of the two wells were calculated and compared with those of Zhuangshi well. The results showed that:(1) The water level changes of three wells have a good correlation in time and space, and there is a good genetic correlation between water level anomaly and its influencing factors. (2) The rainfall load factor of Cixi well is about an order of magnitude smaller than those of Zhuangshi and Beilun wells, which may be related to the location of Cixi well. (3) The wells are located in the Ningbo Basin with multiple aquifers, which makes it possible to carry out observation and basic research of different aquifers in the same structure. Qualified seismic precursor monitoring wells can be selected from the network for the construction of seismic precursor fluid array in the Ningbo Basin.
