- Abstract
The geothermal resources in northern Ordos Basin are characterized by deep burial, high temperature, large reserves and great development potential. Reasonable geophysical prospecting methods can accurately determine the target area, delineate the thermal reservoir structureand provide basis for dnlling. Due to the advantages of magnetotelluric sounding (MT) method in detecting depth, the characteristics of n&sistivity inversion can clearly reflect the distribution and occurrence of water conductivity and thermal conductivity structures in geothermal fields. Based on the previous logging results of EROl and ERO2 geothermal wells, the study recalibrates the geophysical interpretation parameters of ERO3 geothermal well, reveals the horizontal and longitudinal distribution rules of thermal reservoirs within 4 000 m depth, delineates the range of geothermal anomalies and spatial distribution, determines the water-rich location of geothermal water and favorable positions for drilling, and puts forward suggestion s for next work.
