Overview

Randomized trial finds diagenetic mechanisms affect reservoir quality in tight sandstones, suggesting exploration potential.

Key Points

  • This study investigates the genetic mechanisms affecting the quality of tight sandstone reservoirs in the Shaximiao Formation.
  • Conducted multiple analytical methods including thin section observation and scanning electron microscopy.
  • Analyzed fluid inclusion testing and reservoir physical property measurements.
  • Classified diagenetic environments based on compaction, cementation, and dissolution processes.
  • Primary porosity loss of 23.34% due to compaction, while feldspar and laumontite dissolution increased porosity by 5.26% and 4.32%, respectively.
  • Three diagenetic environments identified: compaction-dominated, cementation-dominated, and dissolution-dominated.
  • Differential fluid migration alters authigenic minerals and pore spaces, contributing to reservoir heterogeneity.
