【摘要】：该文对黄村冷水源井的水温固体潮现象进行了观测研究,初步解释了冷水源井的水温固体潮汐的形成机理.通过对黄村观测井进行水温梯度的详细观测及不同深度水温的对比观测研究,得到了黄村井水温潮汐现象的观测结果:(1)黄村冷水源井的水温固体潮的相位与水位的相位是相反的;(2)黄村井水温梯度曲线呈下凹型,特别是在含水层及受含水层进出水影响较大的附近区域下凹程度大,且随着与含水层底板距离逐渐变大,下凹程度也变小;(3)水温传感器的观测值与含水层观测距离存在一定的规律性:距离含水层越远,水温潮汐差越小,直至潮汐变化消失.这说明冷水源井与热水井的水温潮汐现象是不同的,前者是吸热过程,后者是放热过程,由此造成二者水-热动力学特征的不同.
[Abstract]:In this paper, the phenomenon of water temperature solid tide in Huangcun cold water source well is observed and studied, and the formation mechanism of water temperature solid tide in cold water source well is preliminarily explained. Through the detailed observation of the water temperature gradient in Huangcun observation well and the comparative observation of water temperature at different depths, The observed results of water temperature tidal phenomena in Huangcun well are: 1) the phase of water temperature solid tide in Huangcun cold water source well is opposite to the phase of water level) the gradient curve of water temperature in Huangcun well is concave. Especially in the aquifer and in the vicinity of the aquifer that is greatly affected by the inflow and outflow of the aquifer, and with the increase of the distance from the aquifer to the bottom plate of the aquifer, The observed value of the water temperature sensor has certain regularity with the observed distance of the aquifer: the farther away from the aquifer, the smaller the tidal difference of water temperature, until the tidal change disappears. This shows that the water temperature tidal phenomena of cold water source well and hot water well are different, the former is an endothermic process, and the latter is an exothermic process, which results in the difference of the characteristics of water and thermal dynamics between them.
