Overview

This research examines pore structure characteristics affecting gas-bearing properties in the Sichuan Basin, indicating key factors influencing reservoir quality.

Key Points

  • To identify controls on gas-bearing property heterogeneity in tight sandstone reservoirs of the Shaximiao Formation.
  • Systematic examination of pore structure characteristics
  • Utilization of cast thin sections and X-ray diffraction
  • High-pressure mercury injection analysis
  • Assessment of homogeneity and variation coefficients
  • Identified lithic arkose as the predominant reservoir lithology
  • Recognized major factors influencing reservoir quality as sediment provenance and diagenetic minerals
  • Differentiated gas content variability related to reservoir heterogeneity and pore structure differences
