| 摘 要： | 为研究漳州地热田基岩裂隙水系统温度分布特征,建立了新的三维基岩裂隙水系统概念模型,并利用Fluent软件求解模型。结果表明:基岩裂隙热水温度场受到断裂区的强烈控制,在北东—南西向断裂中,强烈对流形成的高温热柱刺穿了基岩顶部形成热田高温中心;基岩热流在断裂区中部高温区达到最大,在北东—南西方向上最大值为343.02mW/m2,在北西—南东方向最大值为368.72mW/m2,并向边缘逐渐降低;第四系孔隙水的存在和运动使得地表热流的最大值和局部值降低。未来漳州热田应加强深部温度的测量研究。

| Abstract: | In order to research temperature distribution characteristics of bedrock fracture groundwater at Zhangzhou geothermal field,a new 3-D conceptual model for bedrock fracture groundwater is established and numerically solved by Fluent software.The results show the temperature distribution is strongly controlled by the fault-fracture system and a high temperature cylinder in the northwest-southeast fault formed by convection of hot water heats top surface of bedrock and thus forms the center high temperature area.The heat flux reaches maximum of 343.02 mW/m2 and 368.72 mW/m2 respectively at center high temperature areas,and reduces towards the edge of the geothermal field.The Quaternary pore water movement reduces the maximum and local heat flux.The future research on Zhangzhou geothermal field should focus on the deep temperature measurement. |
