Abstract
Models of poroelasticity and discrete cracks serve as a basis for a numerical study of filtration in deformable fractured porous media. The influence of the stress-strain state of a medium on its filtration 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 versions of randomly developed systems of cracks with different degrees of coupling.
