摘要

层状夹层盐岩腔体含有大量不溶沉渣，而当前缺乏系统利用沉渣储热能力的分析。因此，为探索耦合盐穴压缩空气储能与沉渣储热的可行性，基于ComsolMultiphysics平台构建了考虑沉渣多孔介质特性的热流固数值模型。首先，研究了不同沉渣含量下腔体在常规压缩空气储能工况下的热力响应，发现沉渣比热容降低了热空气对腔壁的热冲击；沉渣层垂直厚度超过30m时可降低围岩温度波动，采气阶段温度波动小于0.5℃，注气阶段温度波动小于1℃。然后，构建了具有连通道的水平双腔模型，研究了储热工况下的温度场变化。储热模拟显示在运行过程中流出界面温度波动为[45℃

55 ℃]，相比注入界面温度波动[30℃

60 ℃]降低了66%；并且在3个注采周期后，研究发现沉渣温度在[49℃

53 ℃]区间内周期变化，验证了将沉渣作为压缩空气储能系统地下储热模块的可行性。结果表明，沉渣热容量有助于洞壁稳定性，为在富含沉渣盐穴中开发压缩空气-储热综合利用系统提供参考。
