摘要
本文通过在新30号观测井孔里重新放置一套新的测温仪,使新、老水温监测仪在不同深度同时观测,发现在同一井孔中,不同深度的水温探头所记录到的井水温度变化曲线形态是不一样的,也就是观测井放置探头的深度与部位对井水温观测结果有明显的影响。通过对新30井水温试验仪观测数据分析,可以确定探头放置180～185m处,水温日变化有规律,有潮汐显示,而且与同井观测的井水位在日变形态上具有一定的同步性,表现为水位上升时水温上升,水位下降时水温也下降。另外,分析了该井水温探头在不同深度的日变形态和映震灵敏度,并初步确定该井放置水温探头较为合理的观测深度为180m。
A set of new water temperature observation instrument was placed in New 30 well in Xinjiang.When the old and new instruments observed at different depths simultaneously,the record curves are different,so the depth and place where the instruments were installed influence the observation result obviously.Through analyzing the observation data of water temperature test instrument,we found that when the instrument was installed at depth of 180 to 185 m,the water temperature daily variation is regular and changes synchronously with the water level in the same well,and there is tide change.At last,the daily variation shape and earthquake reflecting sensitivity at different depth are analyzed,and the rational instrument installing depth has been preliminarily determined to be 180 m.
