Numerical modeling of problems of geomechanics in the study of an inhomogeneous stress field in the near-wellbore zone

Abstract

Some of the main actual problems of geomechanics related to the numerical simulation of an inhomogeneous stress-strain state in the near-wellbore zone during the development of oil and gas fields are considered. Methods for analyzing the stress field are presented to identify possible zones of destruction of the main structural elements of the well and perforation channels. For slotted perforation, an example of calculating the changes in reservoir permeability during the transformation of effective stresses near the well is given.
