为了探索淮南矿区地热地质特征和矿井深部热害防治对策，系统收集和分析了淮南矿区钻孔井温测井资料，基于近似稳态测温数据，拟合了测温孔孔底温度校正曲线，对简易井温测井钻孔孔底温度进行了校正;采用浅钻孔测温法，对井下巷道围岩温度进行了测定;
在地热研究中地热田高地温的形成原因、为何地热田深部会出现低地温梯度等说法不一, 未有定论。本文对前人所提出的地温场影响因素逐一进行了分析, 采用地热场正演模拟手段, 对有异常热源供热-岩浆囊和无热源的热传导两种情况进行了研究。认为多数异常热源如岩浆囊, 相对于地质演化时间尺度而言, 其冷却速度较快, 并不能直接为地热田供热; 寻找地热田主要在浅部有一定厚度的好的热盖层和深部有高导层的区域进行; 构...
鲁西地区不同岩性地层热响应试验结果浅析
