摘要
天津地热资源丰富,为研究天津地热资源的开采潜力,通过热储法对天津平原区沉积盆地型地热资源进行比较,其中涵盖4 000 m以浅的6个热储层的地热资源量、地热流体储存量、可回收地热资源量,同时利用开采系数法和热量平衡对不同开采条件下的地热流体可采量进行计算,以2013年的实际开采量为样本,对多个计算指标的合理性进行了分析研究。结果证明实际开采量只占理论值的极小部分。人工回灌可以极大地提高地热资源利用率。
It is great necessary to study the geothermal development potential in Tianjin since it contains abundant geothermal resources. In this study, we analysed geothermal reserve, geothermal fluid reserve and recycled geothermal reserve of the six reservoirs, which are lower than 4 000 meters by geothermal reserve method. Based on the actual production in 2013, we applied to production coefficient method and heat balance to calculate the geo- thermal fluid production under various conditions. We found that the actual production is significantly smaller than the theoretical values. Artificial reinjection can increase the use ratio of the geothermal resource.
