Modeling of Filtration and Scattered Fracture in Fractured Zones with Abnormally High Formation Pressure
摘要
Abstract—A model of a double-porosity medium with damageable matrix subject to anomalously high formation pressure is discussed. It is assumed that damage in the matrix enhances mass transfer between the subsystems of the medium. The problem about the coupled fracture and fluid flow process in a fractured-porous medium in one-dimensional (1D) statement is solved numerically. The limited spatial extent of the zone of hydraulically conductive fractures is taken into account.
