水温微动态形成的水热动力学 与地热动力学机制

Mechanisms of water-heat dynamics and earth-heat dynamics of well water temperature micro-behavior

  • 摘要: 以井-含水层热系统分析为基础, 结合井水温度(水温)动态观测到的实际结果, 提出了水温微动态形成的两类基本机制, 即水热动力学机制与地热动力学机制. 水热动力学机制指井水温度的动态是由于水流动产生的热对流引起的变化; 地热动力学机制指井区岩土中大地热流作用或热传导引起的井水温度变化. 结果表明, 多数同震响应是水热动力学机制下生成的水温微动态; 水温的震后效应或变化则多是热传导或深部热流变化引起的, 属于地热动力学机制下生成的水温微动态. 少数水温微动态特征较为复杂, 多是源于井-含水层系统中包含有多个水文地质特征差异明显的含水层, 尚不能简单地用水热或地热动力学机制予以解释.

     

    Abstract: On the basis of analysis on heat system of well-aquifer, combining with practical observation results of well water temperature behaviors, two mechanisms of water-heat dynamics and earth-heat dynamics of well water temperature micro-behavior are presented. The mechanism of water-heat dynamics is that the well water temperature micro-behavior originates from heat transport related to moving of water flow. The mechanism of earth-heat dynamics is that the well water temperature micro-behavior originates from heat flow or heat transfer in the earth. Results show that most coseismic responses of water temperature in a well are micro-behaviors produced under water-heat dynamics mechanism, whereas post-seismic effects or changes of water temperature in a well are micro-behaviors caused by heat conduction or change of deep heat flow, and belong to earth-heat dynamics mechanism. The characteristics of a few micro-behaviors of water temperature in a well are more complicated, which is due to existence of multilayer aquifers in a well-aquifer system. And the hydrogeological characteristics of these aquifers are more obviously different, which cannot be yet explained under the mechanisms of water-heat or earth-heat dynamics.
