DIGITAL ROCK ANALYSIS SYSTEMS AND METHODS WITH RELIABLE MULTIPHASE PERMEABILITY DETERMINATION

摘要

The rock and other materials of pore structure can be by microscopies and the performance of Digital Simulation by determine that multi-phase fluid flow passes through the material. In order to guarantee reliable as a result, digital rock model, first analysis in some embodiments, include by a series of operation: obtaining three-dimensional pore space/substrate model sample; Determine axis; It is more than typical unit body (REV) that the size of this model, which is verified, along flow axes; Selective flow direction; If the statistics that hole extends through mirror image model mismatches different diafiltration phases in given saturation; And whether the minimum nonpercolating sphere sizes for increasing resolution ratio are lower than predetermined threshold. The sequence of operation improves the reliability of testing result, when measurement relative permeability, is supplied to user using the model and display relative permeability measurement.
