Implication

Demonstrates hydrocarbon accumulation patterns in shale gas, indicating significant geological influences in a specific region.

Key Points

  • This research aims to identify the main controlling factors and model the accumulation of shale gas in the Southern Sichuan Basin.
  • Analyzed logging interpretation data from the Wufeng and Longmaxi formations in Luzhou region
  • Utilized techniques including core analysis and focused ion beam scanning electron microscopy
  • Built an accumulation model for shale gas based on reservoir characteristics and structural controls.
  • Deep shale gas reservoir characteristics are primarily controlled by reservoir space features, diagenesis, and structural evolution.
  • Organic-rich siliceous shales exhibit good reservoir performance with high porosity and permeability, especially when under overpressure.
  • The gas retention varies significantly between structural styles, with synclines showing higher gas accumulation than anticlines.
