Application of positron spectroscopy for investigation of threshold space of oil-gas rocks

Abstract

This article considers the possibility of applying the positron annihilation spectroscopy method for investigating the pore space of rocks from oil-gas and methane-coal deposits. The diagnostics of the structure was performed using the method of spectrometry of angular correlation of annihilation rays (ACAR). Using the samples of porous silicon, the authors have shown the applicability of the ACAR method for determination of the average dimensions of spherical and cylindrical nanosized objects and their concentration [Figure not available: see fulltext.] © 2014 Versita Warsaw and Springer-Verlag Wien.
