| 摘 要： | 西藏亚东-谷露裂谷带是新生代的活动构造带，具有构造活跃、地震频繁、热泉广布、大地热流高等特征，孕育了丰富的地热资源。已实现商业开发多年的羊八井地热田和羊易地热田正是位于亚东-谷露裂谷带的中部，而位于该构造带北部的谷露地热田地热资源前景和勘探方向还有待深入认识。为此，本文解析了地表地热构造，对比了羊八井地热模式，分析了谷露地热田的深部热动力学背景，并结合钻井试采资料揭示谷露地热田具有良好的地热资源前景。在此基础上，利用大地电磁和重力预测了谷露地热田的地热分布具有南北分带性，即北部和中部具有深部和浅部两个层次的地热储层，而南部地热储层则以浅部为主。为深入研究亚东-谷露裂谷带的地热系统模式及指导地热勘探开发提供了重要的地球物理依据。

| Abstract: | The Yadong-Gulu rift in Tibet is an active tectonic zone in Cenozoic, characterized by active tectonics, frequent earthquakes, widespread hot springs and high heat flow, and has nurtured abundantly geothermal resources. The Yangbajing geothermal field and Yangyi geothermal field located in the central Yadong-Gulu rift have been commercially developed for decades, while the geothermal prospect and exploration direction in the Gulu geothermal field located in the northern Yadong-Gulu rift need to be furtherly clarified. Therefore, this paper analyzes the surface geothermal geology, discusses the Yangbajing geothermal model, and concludes that the Gulu geothermal field has a good geothermal prospect. The geothermal reservoirs revealed by magnetotelluric and gravity are characteristic of north-south zonation in the Gulu geothermal field. There are deep and shallow geothermal reservoirs in the north and middle of Gulu geothermal field, whereas the geothermal reservoirs in the south are mainly in shallow, which provides important geophysical basis for further understanding the geothermal model of the Yadong-Gulu rift and guiding geothermal exploration of Gulu geothermal filed. |
