OVERPRESSURE TRANSFERENCE：CONCEPT AND WAYS

Overpressure transference may be a kind of widespread phenomenon in overpressure sedimentary basins.Overpressure transference is the increasing of pore fluid pressure in other pressure systems caused by the flow of overpressure fluid released or leaked from overpressure systems.Base on the orientation of overpressure transference,vertical and lateral two types of overpressure transference were divided.The overpressure resulting from overpressure transference was named transference overpressure.The ways of overpressure transference include the injection of overpressure fluid,the migration of overpressure fluid along permeable sandbodies and the dilatation of overpressure compartments.
