Exploration of deep geothermal energy resources with wide field electromagnetic method
-
摘要: 使用广域电磁法勘查了江苏省仪征市捺山地区的深层地热资源,查明了工区的第一热水储层和第二热水储层,钻遇储层出水量大、温度高.勘查结果显示广域电磁法是一种高效的深层地热能资源地球物理勘查方法,具有深度大、分辨率高、野外数据采集快等优点,勘查深度超过1 500 m,是深层地热能资源勘查主要的地球物理勘查方法.Abstract: The basic principle and advantages of wide field electromagnetic methodhave been introduced.Deep geothermal resources in Nashanarea of Yizheng, Jiangsu province have been explored by way of wide field electromagnetic method,and identified the first hot water reservoir and second hot water reservoir which havebigoutput and high temperature.Results show that wide field electromagnetic method is an effective geophysical exploration method for deep geothermal energy resources.It has advantages of deepsurvey, high resolution, fast data acquisition and so on.Its exploration depth is more than 1 500 meters.So,it will become main geophysical exploration method for deep geothermal energy resources.
