Abstract
The acoustic emission memory effect (Kaiser effect) discovered in 1953 by the German scientist Joseph Kaiser is widely used as one of the methods of non-destructive testing of materials. In addition, according to acoustic emission data, it is possible to estimate the level of stresses experienced by rocks in reservoir conditions. In this paper, we consider the results of recording acoustic emission in sedimentary rock samples from the Mesozoic part of the section of Western Siberia. The studying features of the manifestation of acoustic emission signals was carried out on the main lithological varieties (medium-grained sandstone, mudstone, siltstone, sandstone with carbonate cement). In total, 43 samples were analyzed under uniaxial loading and 1 sample under pseudo-triaxial loading. The results of the study are graphs of the dependence of the total number of acoustic emission signals from the stress. The dependence of the number of acoustic emission signals on the group of sedimentary rocks is determined.
