摘要
通过对武汉市地热资源赋存的影响因素进行论述,建立地热资源评价模型。该模型包含地热地质条件、资源量、勘查成本3个因子,将每个因子细分并对其进行量化处理,采用模糊综合评价法对地热勘探风险进行评价,以期达到降低风险、提高地热资源勘探成功率的目的。结果表明西部盆山结合带、襄(樊)—广(济)断裂带近源—混合型、南部凹陷带三个单元地热勘探风险较小,建议作为未来武汉市地热重点研究区。
Based on the discussion of the factors affecting the occurrence of geothermal resources in Wuhan,the evaluation model of geothermal resources is established. The model includes three factors: geothermal geological conditions,resources and exploration cost. Each factor is subdivided and quantified. The risk of geothermal exploration is evaluated by fuzzy comprehensive evaluation method in order to reduce the risk and improve the success rate of geothermal exploration. The results show that the risk of geothermal exploration in the Western basin-mountain junction zone,the XiangfanGuangJi fault zone and the southern depression zone is relatively small. It is suggested that they should be the key geothermal research areas in Wuhan in the future.
