M.mamedaslan@rambler.ru151220191116252812202128122021Copyright © 2019, Mamedova I.M.2019<p>Based on the study of core material, the article proposes a new method for facies analysis of the section of the productive strata of Azerbaijans fields, as well as identifies facies variability direction of the pereryv formation. Methodological aspects of studying the structure of grains of deposits of the productive strata using a binocular microscope are considered. A 3D model of the spatial arrangement of the facies of the alluvial-delta genesis was constructed and their relationship with the structure of the South Caspian Depression was established, which makes it possible to correctly design wells both during prospecting and exploration drilling, and during field development.</p>facies analysis3D analysis of core materialbinocular microscopesedimentation modelфациальный анализ3D-анализ кернового материалабинокулярный микроскопмодель осадконакопления1.Рожков Г.Ф.
