Overview

Analysis of shale gas production and pore structure evolution in different sedimentary environments indicates significant geological implications.

Key Points

  • To understand how sedimentary environments control pore structure and its evolution in the Lower Carboniferous Shale.
  • Analyzed shale samples from various sedimentary environments
  • Measured total organic carbon (TOC) content
  • Conducted X-ray diffraction (XRD) analysis
  • Utilized low-pressure gas adsorption (CO2 and N2)
  • Employed field emission-scanning electron microscopy (FE-SEM)
  • Well SY-1 produced daily gas of 1.1 × 10^4 m3 from the shale.
  • Basin sedimentary environment (BSE) has highest TOC and pore volume.
  • Upper slope sedimentary environment (USSE) shows highest dominance of inorganic pores and lowest TOC.
  • Pore volume and specific surface area decrease from BSE to USSE, while fracture development increases.
  • Developed a model for organic and inorganic pore associations based on mineral types.
