Overview

Analysis reveals factors controlling gas saturation in tight gas reservoirs, suggesting strategies for exploration.

Key Points

  • The differential enrichment of tight gas in the Shaximiao Formation is significantly influenced by reservoir properties.
  • Logging, seismic, experimental, and drilling data were utilized to understand the reservoir characteristics.
  • A tight gas accumulation model was developed, highlighting fault–sand transport systems as key factors for gas migration.
  • Understanding the petrophysical properties and fault distribution can predict tight gas sweet spots effectively.
