Modeling of filtration and scattered fracture in fractured zones with abnormally high formation pressure

Abstract

A model of a double-porosity medium with a damageable matrix under the action of 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 of the coupled process of fracture and fluid flow in a fractured porous medium in one-dimensional (1D) statement is solved numerically. The limited spatial extent of the zone of conductive fractures is taken into account.
