METHOD FOR PRODUCING STATISTICAL digital model full-size core shale ACCORDING Multiscale computed tomography

摘要

A process for preparing statistical digital model of full-sized core shale characterized by a sequence of actions comprising obtaining three-dimensional makrotomograficheskogo image material full length core by computed tomography and identifying areas characterized by a uniform structure of core material on a macroscale, the preparation of three-dimensional mikrotomograficheskogo image representative volume selected for each of the identified domains with a homogeneous structure kernovog material and defining subdomains characterized by a uniform structure of core material at the microscale, receiving via FIB / SEM of three-dimensional images of representative amounts selected for each of the detected subregions to microscale and calculating characteristics of interest in selected representative volumes conversion characteristics obtained on microscale according microtomography and FIB / SEM, and converting the obtained characteristics for microscale macroscale according to macro - and microtomography.
