| 摘 要： | 通过对地质资料的分析，认为该区理论上具有较好的地热生成环境和赋存条件。重点围绕郎邵-葛沟断裂两侧，综合运用地质调查、测温、物探、钻探等手段，对成热地质条件进行调查分析，圈定淳于地热异常区和梁家庄地热异常区2个异常区，分析并初步确定热源为地壳深部的热流，导水导热通道为部邵-葛沟断裂及其次级断裂，热储为深循环对流型带状热储，热储岩性为白垩纪青山群安山岩，埋深1400-2000m，盖层为新近纪、古近纪及白垩纪粘土岩、砂岩等。结合区域地质资料，建立地热资源概念模型，并据此确定了3处拟井位置及孔深。

| Abstract: | Through analysis on geological data, it is regarded that there are good forming environment and occurrence conditions of geothermal in this area. Focusing on both sides of Tangwu --Gegou fault belt, by using geological survey, temperature measurement, geophysical exploration, drilling and other means, geological conditions of geothermal have been surveyed and analyzed. Chunyu geothermal and Liangjiazhuang geothermal anomaly zone have been circled. After analysis, it is determined that the heat source is initially deep crustal heat flow, and thermal conductivity water channels are Tangwu--Gegou fault and its secondary faults. Thermal reservoir is deep con- vection and ribbon type. lithology of geothermal reservoir is andesite in Cretaceous Qingshan group with the depth of 1400-2000m. Its covering layers are Neogene, Paleogene and Cretaceous claystones and sandstones. Combining with regional geological data, a conceptual model of geothermal resources has been set up, and location and hole depth of three proposed wells have been accordingly determined. |
