摘要

Pore structure is one of important factors affecting the properties of sedimentary rocks, however, it is difficult to describe microscopic parameters of the pore structure such as pore geometry, pore-size distribution, and pore space topology. Fractal theory is an effective and available method to quantify the complex and irregular pore structure of rocks. Routine rock properties measurements and high-pressure mercury intrusion tests (HPMI) were performed on a suite of the Bashijiqike tight gas sandstone samples to delineate the pore network characteristics of these reservoir rocks. Thin section epifluorescence and scanning electron microscopy (SEM) analyses were used to gain insight into pore geometry and pore size distribution of these sandstones.
