Procedure for estimating the bulk density of rock samples using X-ray computed tomography dual energy

摘要

A method for estimating the apparent density of at least one target object comprising: i. perform a scan of two or more reference objects with known density and three or more calibration objects bulk density and effective atomic number known, ii. obtain a functional relationship between the error of bulk density and effective atomic number using the values ​​scanning reference objects and calibration objects, iii. perform a scan of the target object and calibration objects, iv. obtain the uncorrected density and effective atomic number for the target object, v. obtaining bulk density corrections using the functional relationship between the error of bulk density and effective atomic number of the reference objects, and the effective atomic number for the target object, and vi. obtaining corrected density using the apparent apparent, wherein steps i the density corrections. and iii. They can be performed in any order.
