Abstract

Настоящее изобретение относится к способу получения характеристической трехмерной модели образца горной породы для исследования пространственных физических характеристик материалов после обработки изображений, полученных методом компьютерной томографии. Способ включает получение трехмерного томографического изображения образца материала, определение областей с однородной структурой материала и присвоение каждой такой области определенного значения плотности материала, присвоение определенного значения пористости для каждого пикселя, присвоение определенного значения абсолютной проницаемости для каждого пикселя, формирование характеристической трехмерной модели на основе значений пористости и проницаемости для каждого пикселя, вычисление абсолютной проницаемости для всего образца или его сегмента в любом направлении методом вычислительной гидрогазодинамики. Техническим результатом является повышение точности и достоверности получаемых данных о свойствах проницаемости образца пористого материала без необходимости привлечения дополнительных финансовых и трудовых ресурсов.
