TRANSFORMATION OF ORGANIC MATTER OF ROCKS FROM DOMANIK DEPOSITS IN HYDROTHERMAL AND PYROLYTIC PROCESSES
Abstract
The objects of the study were samples of Domanik rock from Upper Devonian siliceous-carbonate and carbonate sediments of the Romashkin? oil field, which occurs in the central part of the South Tatarian arch in Tatarstan. The composition of organic matter and mineral rock components and bitumoids extracted from them was studied by thermal analysis, X-ray diffraction analysis, SARA analysis and gas chromatography. Significant differences in the mineralogical composition and content of organic matter are found in samples after their hydrothermal treatment at a temperature of 350пїЅC in the steam medium at the carbon dioxide. Based on the example of these rock samples, pyrolytic experiments were conducted to simulate the processes of conversion of kerogen to free micronized oil at temperatures of 350 and 600пїЅC in a hydrogen medium in a flow system. The content of Mn2+, SO3 -, SO2 - ions in the rock, as well as ions of vanadyl (VO2+) and free radicals (R*) in the pyrolysis products were evaluated using Xband electron paramagnetic resonance (EPR) spectroscopy at frequency of 9.43 GHz. The most significant changes associated with an increase in the concentration of free radicals were observed at 350пїЅC. A new free organic radical C350 was registered In the sample of siliceous-carbonate sediments and a free organic radical C600 пїЅ in carbonate sample, which indicate that the studied rocks did not fully realize their potential in natural hydrocarbon generation processes.
