西昌川32井水温传感器不同投放深度监测能力分析

Testing on the detecting ability with different depth for the temperature sensor in No. 13 well in Xichang

西昌川32井水温传感器曾投放井下两个不同深度,在含水层的不同位置,记录地震和异常变化的能力各有不同,本文对此进行比较分析,用数据说明西昌川32井水温传感器更合理的投放位置。

In order to find a suitable observation levels in where the water temperature changes are sensitive to the earthquake, we put the temperature sensor in two depths, 220 and 260 meter below ground surface, in Xichang No. 32 observation well. Our test results show that clear changes of water temperature in these two depths were not found in the period of operation while 4 earthquakes with the magnitude equal to or greater than M7.0 occurred. And the suitable level of water temperature observation is in aquiclude according to our test.
