| Abstract |
One of the main problems when conducting laboratory tests of rock specimens aimed at determining their mechanical and strength properties is to transfer the test results of relatively small
specimens to sufficiently large areas of a rock massif, often with a complex structure. This is due to the
fact that generalized numerical indicators characterizing the degree of influence of structural heterogeneities of various sizes on the deformation and destruction of rocks and massifs are not yet available.
In addition to heterogeneity, other factors also affect the processes under study, such as the stress state
of the massif, the presence of geological disturbances, macrofractures, etc. These issues are studied in
this paper based on a comparison of the results of experiments performed on the Triaxial Independent
Loading Test System of the Institute of Problems in Vechanics of the Russian Academy of Sciences
using the “hollow cylinder” scheme on specimens with a central hole of 10 and 20 mm in diameter and
physical modeling of deformation processes in the vicinity of wells with a decrease in pressure at their
bottomhole for reservoir rocks of the Prirazlomnoye oil field. |
