Abstract

Overpressure has close realationship with reservoir forming and it has many cause of formation,such as: undercompaction,hydrothermal pressurization,clay mineral dehydration in it’s transformation,structure extrusion,hydrocarbon generation and so on.however,the undercompaction in the fast deposition of basin and the generation of hydrocarbon are the main reasons of the overpressure forming.Overpressure can restrain the generation of hydrocarbon,reinforce the seal ability of caprock,improve the character.

Key words： Overpressure; Cause; Reservoir forming.
