五大连池地热研究

Wudalianchi geothermal research

为合理利用地热资源,通过对五大连池的各种地热显示和地热要素的对比、分析,得到五大连池地壳中存在浅部地热源的结论。根据地热要素分析地壳中存在岩浆房,确定了地热储热层、盖层和导热通道,分析了该区冷泉和局部地热异常的成因。结果表明:研究区表观为冷泉,从沉积特征看,第四系玄武岩沉积是重要的隔热因素。地热异常仅在NW向张性断裂局部地段出露。

Aimed at the rational utilization of geothermal resources, this paper proposes the occur- rence of the shallow ground source heat in the earth＇ s crust in Wudalianchi as a result of the analysis and comparison of the Wudalianchi geothermal various display and geothermal elements. The existence of mag- ma in the crust as suggested by the analysis of geothermal elements determines the geothermal reservoir, caprock, and heat conduction pathway. The paper adds to the analysis of the cold seeps and local geo- thermal anomaly genesis. The results show that the study area is described as cold seeps and in terms of the sedimentary features, quaternary basalt sedimentary is important insulation factor. Geothermal anoma- ly occurs only in the NW-trending tensional faults local area.
