Abstract
Background. Image analysis of the granulometric composition in rock thin sections is an effective method that complements petrographic and sedimentation analyzes of reservoir rocks. However, due to imperfect research results and the specifics of rock structure, the application method has a number of limitations. Objective. The article shows the effectiveness of using image analysis for several groups of terrigenous rocks that differ in structural and mineral parameters. Materials and methods. The study was carried out using an optical microscope with the KERN S7 petrographic research analyzer. Results. The work outlines the scope and main limitations of image analysis. It also shows the need for manual adjustment of the image of certain types of rocks and control of the results using laboratory research methods. Conclusions. The results of the work will help to select a rational and effective complex for laboratory analysis of reservoir rocks, depending on their lithological features.
