摘　　要：Hydrofracturing has been found in a numbr of sedimentary basins throughout the world, which pay an important role in the migration of hydrocarbon and compaction of deposits in overpressured impermeable muddy rock. The forming processes of hydrofracture in the basin evolution has been simulated and the associated episodic compaction of deposits has been evaluated. The modelling results indicate that episodic compacting process in impermeable rocks induced by hydrofracturing is an important way of sediment compaction.Hydrofracturing has been found in a numbr of sedimentary bahs throughout the world, which pay an important role in the migration of hydrocarbon and compaction of deposits in overpressured impermeable muddy rock.
