The present application relates to the technical field of deep geothermal prediction and detection, and particularly relates to a multi-element fusion deep geothermal detection method, comprising the following steps: constructing a multi-element evaluation structure and mapping it into a
score propagation network, obtaining multi-source basic data to generate element scores and uncertainty information, extracting
time changes to construct time elements, introducing a
nonlinear coupling relationship to dynamically correct the
score propagation, triggering constraint rules based on uncertainty to regulate the propagation amplitude and path, recording the influence path and contribution ratio through
score propagation, and finally forming a comprehensive score corresponding to the target area comprehensive node, realizing the structured, dynamic and interpretable evaluation of the deep geothermal
system. In the present application, by constructing a multi-element evaluation structure and mapping it into a score propagation network, the
system integration and step-by-step transmission of multi-element information are realized, the one-sidedness of traditional single-parameter
local evaluation is improved, and the comprehensive reflection ability of deep geothermal characteristics is improved.
