摘要:
通过巢湖皖14井高精度水温观测环境及数字化改造以来的观测资料，分析不同深度（-160 m、-195 m）处水温变化特征。以2012年4月11日印尼8.6级地震为例，巢湖皖14井水温同震响应所获得的数据为分析基础，利用Ansys中的热分析模型进行数值模拟，研究了同震响应过程中井孔系统水温度变化与热量传递间的关系及机理。模拟结果显示：水温数值模拟曲线与实际测量数据曲线一致，该井水温同震响应表现为下降特征，主要是热对流所致。
Abstract:
According to the high-precision observation environment of water temperature in well Wan 14 of Chaohu Lake and the observation data since digital transformation，the characteristics of water temperature variation at different depths（-160 m，-195 m）are analyzed. Taking the Indonesian M8.6 earthquake occurred on April 11th，2012 as an example，and based on data got from the co-seismic response of water temperature in Wan 14 well，the relationship and mechanism between water temperature changes and heat transfer in the borehole system during the co-seismic response are studied by using numerical simulation based on thermal analysis model in Ansys. The simulation results show that the numerical simulation curve of water temperature is consistent with the actual measured data，and the co-seismic response of the well water temperature，shown to be a decreasing one，is mainly caused by thermal convection.
