Abstract：This paper analyzed the water temperature observation data from three layers of 180 m,295 m,and 330 m in the well of Yong'an Refrigeration Plant.Combining well structure and gradient variations,the paper compared the characteristics and differences of long-term and short-term background dynamics,intrinsic quality,and various interferences in different layers.The analysis reveals that the water temperature of the three layers in this well shows significant tidal dynamics.The annual dynamics demonstrate a fluctuation-jump pattern,while both daily and monthly dynamics show clear bimodal and double valley earth tide patterns.The interference patterns of natural environment and power-supply are basically the same,while the internal quality,noise level,and sensitivity to earthquake response are directly affected by the placement depth.The layer further away from the aquifer with more stable gradients demonstrates superior performance characteristics,including reduced noise levels,enhanced data quality,and improved capability to record coseismic responses.Conversely,it is not easy to highlight the stress change information of the underground aquifer.Finally,based on the analysis results,the optimal layer for water temperature observation in the well was discussed,which can provide reference for analyzing the characteristics of water temperature of different layers in other wells and selecting reasonable placement layers.
