青海省井孔水温观测结果分析——以德令哈等5个观测井为例

选取青海前兆台网的德令哈等5个井孔开展水温对比观测,对这五个井孔的水温原始观测数据和对比观测数据进行对比分析,从两组数据变化形态、差值、日变幅等方面发现不同的井孔两套数据的相似程度不同,其中以德令哈台为最好,湟源和格尔木次之,互助和佐署井则较差。分析认为主要原因有探头安装情况、仪器型号和仪器工作状态的影响。

Observation Results Analysis of Well Water Temperature in Qinghai---A Case-study of Delingha and other Observation Wells

In this paper, the water temperature of Delingha and other wells, which are the precursor network of Qinghai, is selected to carry out water temperature contrast observation. After comparing and analyzing the original observation data and the contrast observation data of the water temperature of the five wells, it found that the similarity degree of the two sets of data from different wells is different, in terms of the two groups of data changes in morphology, the difference, the daily variation amplitude and so on. Among them, Delingha station is the best, Huangyuan and Golmud take second place, Huzhu and Zuoshujing are poor. The main reasons are the influence of the probe installation, the model of the instrument and the working status of the instrument.
