Overview

Randomized trial investigates pore structure in deep-buried coal reservoirs, suggesting implications for resource evaluation.

Key Points

  • The study aims to understand the multi-scale pore heterogeneity in deep-buried coal reservoirs and its implications for methane extraction.
  • Integrates low-temperature CO2/N2 adsorption and high-pressure mercury intrusion experiments.
  • Applies segmented monofractal quantification and multi-fractal singularity analysis.
  • Defines eight segmented single-fractal dimensions to assess pore characteristics.
  • Micropores <1.2 nm show the highest fractal dimension and strongest heterogeneity, acting as primary methane storage.
  • Mesopores (1.1-8 nm) exhibit the lowest fractal dimension, serving mainly as migration pathways for gas.
  • Macropores demonstrate increased heterogeneity with size; a bimodal pore structure is established with both micropores and macropores present.
