METHOD OF MAKING ROCK-PORE MICROMODEL INVOLVING GENERATION OF AN ACCURATE AND RELIABLE TEMPLATE IMAGE OF AN ACTUAL RESERVOIR ROCK PORE SYSTEM

摘要

ABSTRACTA method of making a glass micromodel of a pore system foundin petroleum reservoir rock wherein a computer-generated two-dimensionalbinary image of the actual rock pore system taken in thin section is used toproduce a template for etched reproduction of the pore system in the glassmodel plate of the micromodel. The template is produced by digitizing avideo image of a view of the rock in thin section, which thin section includesinjection dyed material to make the pore system visible, processing thedigitized video image through a digital filter so as to effect projection ofthe three-dimensional aspects of the pore connectedness and geometryviewed through overlying mineral onto the plane of the imaged view toobtain a two-dimensional template image of the three-dimensional poresystem with pores accurately coordinated and pore geometry relationshipsreliably preserved.
