- Аннотация: The paper presents the results of physical modeling of deformation, fracture and filtration processes in Achimov deposits reservoirs of the Urengoy gas condensate field. At the experiments, the influence of stresses arising in the vicinity of wells during their drilling and operation on the filtration properties of the rocks of the Achimov deposits was studied. The experiments were carried out on the unique Triaxial Independent Loading Test System of the IPMech RAS (TILTS) which allows in cubic rock samples to recreate any real stresses arising in a bottom hole formation zone and to study their effect on filtration properties of rocks. During the experiments, the stress states arising near an open borehole and near the tip of a perforation hole were simulated. A direct modeling of the filtration processes near an uncased well at a decrease in bottom-hole pressure was carried out. The research results confirmed the prospect of using the geomechanical approach to implement new technologies including the directed unloading formation method (DUF) for the effective development of deposits with low permeability reservoirs. The conducted studies are important both scientifically and in practice to justify technical and technological solutions in the development of deposits with hard-to-recover reserves.
