摘要
天津滨海新区中新生态城位于Ⅳ级构造单元北塘凹陷的中部,有明化镇组、馆陶组和东营组三个中深部热储层,地温梯度2.4～2.9℃/100 m,具有较好的中深部地热资源赋存条件,通过勘查初步估计深部中低温地热资源可开采量8.3×105 m3/a。根据中新生态城的工程地质和水文地质条件分析,该区浅层地热资源开发比较适合利用地埋管地源热泵系统,经过调查评价中新生态城可循环利用的浅层地热能可达1.69×105 kW。
Sino-Singapore Tianjin Eco-city of Binhai New Area is located in the middle of grade Ⅳ tectonic units of Beitang depression,in which there are three middle-deep geothermal reservoirs named Minghuazhen,Guantao and Dongying group.The geothermal gradient in this area is 2.4～2.9℃/100 m,and there are good hosting conditions of middle-deep geothermal resources.After the explorating,the authors estimated preliminarily that the exploitable reserves of low-middle temperature geothermal resources is about 8.3×10^5 m^3/a.According to the geological and hydrogeological condition analysis in Sino-Singapore Tianjin Eco-city,the shallow geothermal resources of the area is relatively suitable for using heat pump system of ground-source pipe.A total of shallow recycling geothermal energy can rearch up to 1.69 × 10^5 kW by the calculation.
