摘　　要：基于静乐井36个层位水温试验资料,综合分析各个层位水温的变化特征。可以看出,静乐井水温存在3个梯度段,不同深度点水温存在不同的日变动态。20~40 m日变动态无规律,与水位变化不相关;60~280 m存在不同程度的潮汐响应,与水位变化呈正相关;290~353 m存在不同程度的潮汐响应,与水位变化动态呈负相关;356 m以下日变形态无固体潮变化,数据变化较稳定,基本不受水位影响。结合井区水文地质条件及钻孔资料,得出静乐井290~353 m水温变化动态与井孔结构及区域水文地质条件有一定关系。Based on the water temperature test data of 36 layers in Jingle well and the comprehensive analysis of the variation characteristics of water temperature in each layer,it can be seen that there are three gradient sections of water temperature in Jingle well,and there are different daily variation dynamics of water temperature at different depth points.The daily variation of 20~40m is irregular and not related to the change of water level.There are different degrees of tidal response at 60~280m,which is positively correlated with the change of water level.There are different degrees of tidal response at 290~353m,which is negatively correlated with the dynamic change of water level.There is no change of earth tide in the daily variation form below 356m,and the data change is relatively stable,which is basically not affected by the water level.Combined with the analysis of hydrogeological conditions and drilling data in the well area,it is concluded that the water temperature variation of 290~353m in Jingle well is related to the well structure and regional hydrogeological conditions.
