Overview

Randomized trial investigates hydrocarbon accumulation mechanisms in the Ediacaran Dengying Formation, suggesting new exploration implications.

Key Points

  • The study aims to elucidate the complex hydrocarbon accumulation history of the Dengying 2nd Member in the Sichuan Basin.
  • Integrated data from cathodoluminescence (CL), trace element analysis, U–Pb geochronology, and fluid-inclusion microthermometry.
  • Established paragenetic sequence consisting of eight mineral precipitation and hydrocarbon emplacement phases.
  • Developed simulation models for hydrocarbon migration and accumulation processes during key tectonic stages.
  • Identified a four-stage hydrocarbon accumulation model during the Indosinian and Himalayan periods.
  • Findings indicate that the distribution of paleo-oil pools significantly influences contemporary gas accumulations.
  • Observed zones of water correlation mainly in lower intervals of the Dengying 2nd Member.
