Overview

Randomized trial investigates pore structure characteristics in shale gas reservoirs, suggesting improved development methods.

Key Points

  • This study aims to understand the complex pore structures and fractal characteristics of gas shale to enhance shale gas accumulation and its development.
  • Utilized 12 Taiyuan Formation shale samples for analysis.
  • Applied fractal theory alongside mercury intrusion porosimetry and N2 adsorption to assess pore structures.
  • Conducted scanning electron microscopy for imagery analysis of pore types.
  • Fractal dimension D_M1 values ranged from 2.3060 to 2.6528 in mercury intrusion tests.
  • D_N1 values varied from 2.4780 to 2.6387 and D_N2 values from 2.5239 to 2.7388 using the Frenkel-Halsey-Hill method.
  • Macropores primarily ranged around 0.2 mm, with the largest micro-mesopore volume peak around 50 nm.
