Abstract
A method for predicting a deep geothermal field based on a temperature, pressure, and resistivity coupling constraint includes: equally dividing logging resistivity-overburden pressure-temperature data of m boreholes in a study area into N formations on a depth basis, and normalizing resistivity in each formation; deducing an accurate relationship characterization between a normalized resistivity, a temperature and a pressure in different formations of different formations; inverting an electromagnetic data volume in the study area to obtain a resistivity distribution characteristic, equally dividing an inverted resistivity into M formations, and normalizing the inverted resistivity into a normalized inverted resistivity; inverting a density distribution based on gravity observation data, and converting the density distribution into an overburden pressure; and calculating a distribution characteristic of a deep underground temperature field based on the accurate relationship characterization in different formations, the normalized inverted resistivity, and the overburden pressure.
