With the proposal of carbon peak and carbon neutralization targets, dry hot rock is valued as a new clean and renewable energy source.China is rich in dry hot rock resources, but mature and reliable resource evaluation techniques and exploration methods have not been formed.This research method combines deep exploration with shallow drilling, selects geothermal anomaly area by using heavy magnetic, electric, seismic and thermal joint interpretation technology, verifies geophysical polysolicity by applying massive drilling data from the oilfield, and traps the dry hot rock target area.The research results show that the Qiqihar-Daqing-Harbin area in northern Songliao Basin is a regional geothermal abnormal area; relative impedance combined with seismic profile to lock dry hot rock target area; physical exploration and geological joint interpretation technology is more rapid and more accurate than a single physical exploration technology.Comprehensive analysis believes that the high resistance granite body of "col" in the ancient central uplift zone, with exhibition area of 502km2, thickness of 150~330m, static formation temperature of 3350 m reaches 150 degrees, high rock thermal conductivity, deep fracture and base fracture development, and the area is a fragmented granite weathered shell, easy to artificial reservoir construction,is the preferred target area of dry hot rock.
