Dynamic Hydrogen Diffusion Evaluation in Rock Pores

The patent creates a virtual pore model that replicates the physical pore structure of rock formations. This virtual model copies the essential characteristics (pore size distribution, connectivity, surface area) of actual rock pores, allowing simulation of hydrogen diffusion without the errors of traditional experimental methods. The virtual model serves as an accurate copy that can be manipulated and measured precisely.

The patent replaces physical experimental measurements with computational simulation. Instead of conducting laboratory experiments to measure diffusion coefficients, the system uses molecular dynamics simulations on a virtual pore model to calculate diffusion behavior. This substitution eliminates the measurement errors and limitations of experimental methods while providing more accurate quantitative evaluation.

The patent implements a dynamic pore model that can simulate diffusion under varying temperature and pressure conditions. The virtual pore model allows for dynamic adjustment of environmental parameters (temperature, pressure) and observes how hydrogen diffusion responds to these changes. This dynamic capability enables accurate evaluation of diffusion processes under different geological conditions without requiring multiple separate models.

The virtual pore model serves multiple functions: it can simulate diffusion under various temperature and pressure conditions, evaluate different gas types, and assess the impact of pore structure variations. This multi-functional design allows a single model framework to handle diverse evaluation scenarios, improving adaptability while managing complexity through unified methodology.
