摘要
On the basis of the monitoring conditions of water temperature and comparative observation data for nearly 10 years of water temperature in the Haikou ZK26 well,the spectrum characteristics of water temperatures which are in different layers(-153 m,-336 m,-510 m) are analyzed,and the micro-behaviors are studied in different observation layers.The results of comparative observation showed that,Haikou ZK26 well temperature in different layers display different micro-behavior characteristics because of the different spectrum characteristics,hydrological conditions and hydraulic properties.The aquifer layer of-153 m locates in negative gradient,mainly in the low frequency band and the noise is weak,so the-153 m temperature show clear micro-dynamic characteristics,such as tidal effects,earthquake precursor and post-seismic;while the non-aquifer layers-336 m and-510 m are mainly in the high frequency band and the noises are strong with poor micro-dynamic information.
