THE POSSIBILITIES OF X-RAY FLUORESCENCE SPECTRAL METHOD IN THE DETERMINATION OF THE ELEMENTAL COMPOSITION OF CORE MATERIAL
In the article an analysis of composition of core material using x-ray fluorescence is described. The analysis was carried out on an energy dispersive x-ray fluorescence spectrometer EDX-800HS Shimadzu company with the rhodium anode x-ray tube (the voltage of 15-50 kV and current of 20 to 1000 μa). For the analysis the method of fundamental parameters was chosen provided by software support of the device using channel measurements [Ti-U], [C-Sc], [S-K] in atmosphere of vacuum, collimator of 5 mm and measurement time 15 min. According to the results of the studies of the elemental composition of the cores, there were 16 following elements identified in the samples: Si, Al, K, Ca, Cl, S, Na, Fe, Mg, Zr, Ti, Rb, Sr, Zn, Ba, Cu, that will allow identification of optimal oil and gas-bearing shales, if you have additional information about the number and maturity of organic matter, as well as the type of kerogen.
