AI Technical Summary

Technical Problem

Existing methods for evaluating natural hydrogen exploration sites lack flexibility in adapting to different geological environments and hydrogen source characteristics, and cannot accurately reflect the concentration and migration trends of underground natural hydrogen, resulting in limitations in the evaluation of exploration sites.

Method used

By collecting geological data, gas composition and isotope distribution information of the target area, a three-dimensional geological model is constructed using three-dimensional geological modeling software. A dual-permeability medium seepage model based on Darcy's law is loaded, and transient numerical simulation is performed by coupling the rare matter transfer field and the heat conduction field to determine the natural hydrogen concentration distribution data, thereby identifying favorable exploration areas.

Benefits of technology

It enables dynamic quantitative prediction of natural hydrogen exploration areas, improves the objectivity of evaluation results and the accuracy of exploration, and avoids the subjectivity and limitations of traditional methods.
