摘要
通过沙河、温泉和乌苏井连续6个月的对比观测,对记录的资料进行分析,认为6套仪器记录的观测数据真实可靠.在沙河和温泉井的同一观测深度上,温度总体变化趋势、变化形态甚至在细节方面都是一致的,其相关系数接近于1,通过平移两条曲线基本重合;在乌苏井不同深度(250m和700m)的对比观测,两条曲线形态还是比较一致的.由于两个传感器所处的观测深度不同,在某些细节方面其表现还是有所不同.本文总结出在地热前兆台站安装两套地热仪进行对比观测的具体操作方法,从而解决了实际观测中出现异常时不能确认是前兆异常还是仪器故障的难点.
By analyzing 6 month comparative geothermal observations in 3 wells at Shahe, Wenquan and Wusu stations, respectively, we conclude that the data obtained from the six observational instruments in these stations are reliable. The observations at the same depth of the Shahe and Wenquan well show that the overall trend and pattern, and even details, of the observed temperature variations are the same, and the correlation coefficient of these observations is close to 1. In the Wusu well the observation curves at the two depths of 250 m and 700 m are overall the same, but some details of the observations are deferent due to the sensors being at different depth. This article summarizes the specific operation method of installing two sets of digital thermometers in the same well for comparative observation, and solves the difficulty in excluding the instrument trouble when abnormal observations appear.
