Abstract

Micro-structural attributes of Chumathang granite from Leh, India, were experimentally determined in the temperature range from 25 to 600 °C for enhanced geothermal systems (EGS). P-wave velocity, thermal crack generation, and pore attributes were analyzed using a combination of pulse ultrasonic velocity study, 3D X-ray tomography and low-pressure gas adsorption experiments, respectively. Results indicate that thermal crack development is driven by mineral composition and differential thermal expansion, with a significant increase in the thermal damage factor between 450 and 600 , accompanied by visible cracks at 600 . Surface area and pore volume decreased up to 300 due to mineral dissolution, then slightly increased up to 600 due to microfracture formation. Pore size distribution showed a dominance of coarser mesopores, and fractal dimensions decreased with temperature, reflecting simpler pore geometries. These findings enhance the understanding of granite's microstructural changes under thermal stress, informing the optimization of EGS heat extraction efficiency.

摘要

对来自印度列城楚马唐的花岗岩微观结构属性进行了实验测定，实验温度范围为25至600°C，用于增强型地热系统（EGS）。分别结合脉冲超声速度研究、三维X射线断层扫描和低压气体吸附实验，对纵波速度、热裂纹生成和孔隙属性进行了分析。结果表明，热裂纹的发展受矿物成分和热膨胀差异驱动，在450至600°C之间热损伤因子显著增加，在600°C时出现可见裂纹。由于矿物溶解，表面积和孔隙体积在300°C之前下降，然后由于微裂缝形成在600°C之前略有增加。孔径分布显示粗中孔占主导，分形维数随温度降低，反映出孔隙几何形状更简单。这些发现增进了对热应力作用下花岗岩微观结构变化的理解，为优化增强型地热系统的热提取效率提供了依据。
