Structure-texture peculiarities influence on petrophysical properties of Neftekumsk carbonate sediments

Abstract

The analysis of structure-texture peculiarities of carbonate sediments of Neftekumsk' reservoir within the limits of Zimne-Stavkinsko-Pravoberezhny field was realized in the field of massive bioherm buildups and interreef lowerings in accordance with data of the core analyses. The existing pore space was divided into structure-texture classes. The correlations between petrofabrics and petrophysical parameters were determined. The received data can be used for describing of the three-dimensional distribution of petrophysical properties with the aim to increase the quality of three-dimensional (3-D) geological models
