RESULTS OF ANISOTROPY MICROSTRUCTURE OF CARBONATE STRATA BY ELECTRON MICROSCOPY AND COMPUTER IMAGE ANALYSIS
Abstract
In this paper we discuss the study methods and present the electron microscopy results of microstructural anisotropy and pore space testing of the carbonate rocks full-sized core samples, preliminary tested for filtration and physical properties anisotropy determination. The microstructural and pore space azimuthal anisotropy was experementally revealed in the complex-pore-space-structure carbonate rocks samples. Based on digital image processing, important conclusions were made on large-sized-pore space predominant influence on the filtration properties azimuthal anisotropy which must be taken into account during the hydrocarbonate reservoir development.
Key words: carbonate rocks, microstructure, pore space, cathodoluminescence, azimuthal anisotropy, scanning electron microscope, digital image processing.
