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.
