Characteristics and Controlling Factors of Tight Sandstone Reservoirs in the Deep Sags of Rifted Lacustrine Basins: A Case Study of the Ek 2 Member, Cangdong Sag, Bohai Bay Basin
Deeply buried tight sandstones have emerged as important exploration targets in rifted lacustrine basins. However, reservoir quality generally declines significantly at burial depths exceeding 5000 m. The mechanisms responsible for the preservation of effective pore systems remain poorly understood. This study inve...
