摘　　要：根据易门井138.5 m和153.0 m深度水温观测数据资料,综合分析不同深度水温日变、年变曲线形态、变化速率,对比分析易门井不同深度水温数据异常变化的同步性和差异性特征发现,易门井同层水温日变幅、日均值一阶差分波动幅度长期稳定且基本一致。138.5 m深度水温日幅差、日均值一阶差分波动幅度明显大于153.0 m深度水温。不同深度水温显示出基本相同的长期变化趋势——小幅振荡上升型走势,153.0 m深度水温上升速率略快于138.5 m深度水温。Based on the water temperature observation data of Yimen wells at depths of 138.5 m and 153.0 m,we comprehensively analysed the morphology and rate of change of the daily and annual water temperature curves at different depths,and compared and analysed the synchronicity and difference characteristics of the anomalous changes of the water temperature data at different depths of Yimen wells.It is found that the daily amplitude and first-order difference fluctuation of daily mean value of water temperature in the same layer of Yimen wells are basically the same for a long period of time,while the daily amplitude and first-order difference fluctuation of daily mean value of water temperature at 138.5 m is obviously larger than that at 153.0 m.The water temperature at different depths shows basic changes of daily and annual temperature curves.The long-term trend of water temperature at different depths is basically the same-small oscillation upward trend,but the rate of increase of water temperature at 153.0 m depth is slightly faster than that at 138.5 m depth.When water temperature anomalies occur,comparative analyses of water temperature data from different depths in the same well are carried out to preliminarily investigate the synchronicity and variability of water temperature anomalies at different depths in the Yimen well.
