大地电场岩性探测在贵州地热勘探中的应用

Application of the Earth Electric Field Lithology Detection Technique to Geothermal Exploration in Guizhou

通过与贵州沿河和平镇ZK1地热井的地球物理测井数据对比分析,大地电场岩性探测技术能较为精准的探测深部热储的埋藏深度和含水性。作为一种直接判断深部热储含水性的新方法,大地电场岩性探测技术解决了其他地球物理方法无法解决的深部热储含水性问题,降低了地热资源勘探的风险,特别在断裂控热地区,质测效果更好。可在今后的地热水资源勘探中大力推广。

Comparative analysis the earth electric field lithology detection data and geophysical logging data of ZK1 geothermal well in Yanheping Town of Guizhou, the earth electric field lithology detection can be more accurate detection the burial depth and aquosity of deep geothermal reservoir. As a new technology to directly determine aquosity of the deep geothermal reservoir,the earth electric field detdction can reduce the risk of exploration of geothermal resources,a new technology vigorously promoted in the explo-ration of geothermal water resources in the future.
