摘要

山东省淄博市高青地区地热资源为层状砂岩类裂隙-孔隙型地热,地热概念模型显示,地热源主要来自地壳深处及上地幔的传导热,热储层主要为较大厚度的新近纪馆陶组和古近纪东营组砂层,高青断裂为导水断裂,热储盖层为巨厚的第四系和新近系明化镇组粘性土层。评估高青县地热资源量为1.74×1019J,地热流体可开采总量为6.57×106m3/a,以地热供暖方式有效利用地热资源,节煤量可达25 879.71 t/a,环境效益显著。
        Gaoqing area locates in Zibo city of Shandong province,where the geothermal resource belongs to malti- strata fissure- pore type. In the geothermal conceptual model,the main geothermal heat source has been the terrestrial heat flow of deep earth's crust,and the geothermal reservoir can be divided into 2 types,that is Neogene Guantao formation and Paleo-gene Dongying formation. Furthermore,Gaoqing Fracture may be the heat water transfer channel,the clay layers of Quaternary and Neogene Minghuazhen have been regarded as the cap rock. The geothermal resources assessment show that geothermal reserves may be 1. 74 × 1019 J and the exploitable reserves of geothermal fluid may be 6. 57 × 106m3/ a,which can be used as the heat source of central heating. Absolutely,coal saving will be 25 879. 71 t / a and provide some great environmental benefit.
