Stress-strain state of the bottomhole zone during hydraulic fracturing

The paper is devoted to the study of mechanical processes in the near-wellbore zone of the formation during hydraulic fracturing operations.The distribution of stresses and strains in the reservoir rocks under high-pressure injection of the working fluid is analyzed.The influence of the geomechanical properties of rocks and injection pressure on the formation of the fracture system is considered.The research results make it possible to optimize hydraulic fracturing parameters in order to improve the efficiency of reservoir stimulation.
