Treffer: ЦИФРОВА МОДЕЛЬ ПРИРОДНИХ КЕРНІВ ІЗ ЗАСТОСУВАННЯМ МЕТОДІВ ГЕОМЕТРИЧНОГО ПРОЕКТУВАННЯ.

The article aims to create a digital model of rock-collector cores using the problem of packing spherical particles in a cylindrical container. A new approach to the mathematical modeling of the rock-collector structure is proposed. The computation of its porosity is provided. A mathematical model of the problem of placing the maximum number of spheres with different diameters in a cylindrical container is presented. A solution algorithm is developed based on the optimization by groups of variables and a lattice decomposition strategy. The results of experimental petrophysical studies of real well cores are used as input data. The modeling results provide a good approximation of the absolute porosity of the natural prototype. The application of this approach will help improve hydrocarbon extraction technologies and increase their efficiency. [ABSTRACT FROM AUTHOR]
