Multi-Stage Fluid Charging and Critical Period of Hydrocarbon Accumulation of the Sinian Dengying Formation in Central Sichuan Basin

摘要

Objective The natural gas exploration of the Sinian reservoirs in the central Sichuan Basin has made a significant breakthrough in recent years,and has thus attracted much attention among geologists.The Sichuan Basin is known to have complicated geological settings,which has experienced multiple stages of tectonic evolution,fluid charging and
