2015年11月至2016年8月诸城井完成了水温不同深度对比观测仪器安装调试与产出数据的试验,在对产出数据进行直观和定性分析的基础上,对不同深度、同层位、不同通道的2套地热水位综合观测仪产出数据进行了趋势、方差和均值的一致性检验。结果 表明:诸城井不同深度水温观测数据与地温梯度测试结果基本一致,显示水温产出数据是可靠的; 经一致性检验,同层位水温变化趋势、方差一致,但均值不一致,表明综合观测仪器产出数据间有一定的系统误差,数据变化本底值有一定的差异。

From November 2015 to August 2016,we have completed the installation and debugging of contrast observation equipment as well as the test of output data at water temperature of different depth in Zhucheng well. Based on the intuitive and qualitative analysis of the output data,we have tested the consistency of the trend,variance and mean of output data from two sets of different channels at water temperature of different depth of the same layer in the well. The observation data of water temperature in different depth of the well is basically consistent with the result of geothermal gradient,which shows that the output data of water temperature is reliable. The results of consistency test with the observation data of water temperature at contrast layers in the well confirmed the same horizon temperature change trend and variance,but the mean is not same,which shows that the output data from comprehensive observation instruments showing the system error and that the background value of data change is certain different.
