Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

Models of poroelasticity and discrete fractures serve as a basis for a numerical study of a fluid flow in deformable fractured porous media. The influence of the stress-strain state of a medium on its flow properties is considered. Oil displacement from fractured formations is investigated. It is shown that compressive stresses have a significant impact on the efficiency of oil displacement. Calculations are carried out for three variants of randomly generated systems of fractures with different degrees of connectivity.
