Depositional environment and composition of dispersed organic matter of the lower Jurassic-Paleozoic rocks in the Archinskaya field (south-east of Western Siberia)
Numerous discussions raise the question about the origin of oil in the weathering crust during the Paleozoic era; the answer for this question may lead to a more accurate estimation of the oil and gas potential in these deposits. We characterized the composition of the maximum potential biomarker groups of eight rock samples from the contact zone of the Lower Jurassic and Paleozoic sediments from Archinskaya well 54, in order to reconstruct the paleo-conditions of organic matter accumulation and identify the oil-source potential. Extraction of bituminous components from rock samples was done using 7% methanol in chloroform. Concentrates of hydrocarbons (HC) and metalloporphyrins were obtained by adsorption chromatography at a column with alumina IV activity levels. Eluants were hexane, CCl4, benzene, and benzene-chloroform mixture. Detailed analysis of the component composition of the hexane fraction containing НС was realized using magnetic chromatography-mass spectrometer DFS by "ThermoScientific" company (Germany). The analysis of the results demonstrates that the accumulation of organic matter (OM) in the investigated Paleozoic cross section occurred in the marine environment, which is evidenced by the presence of vanadil complexes of porphyrins, composition and distribution of n-alkanes, terpane composition and the ratio of isosterane isomers. Values of the ratio of gammacerane to hopane indicate low salinity of the sedimentary basin. OM is thermally mature, which is evidenced by the composition of hopanes, homohopanes, and the composition of phenanthrene isomers. The Togur suite OM is characterized by the heterogeneous composition in Tomsk Region, the distribution of n-alkanes varies considerably from well to well. The instability of paleoenvironments during the Togur time in comparison with the Paleozoic time is characterized by a wider range of values of geochemical parameters. Also values of geochemical parameters of Togur and Paleozoic OM associated with distribution of alkanes, steranes and hopanes are significantly different. Assemblage of the data indicates the variety of formation conditions of Togur and Paleozoic dispersed organic matter and makes them potential oil sources with higher thermal maturity of Paleozoic sediments. Aryl isoprenoids at the Archinskaya area were recorded for the first time. Aryl isoprenoid index (AIR), which reflects stability changes of hydrogen sulphide contamination zone during sedimentation, was calculated. Relative content of aryl isoprenoids, which decreases with the increasing AIR and the changing Pr/Ph ratio, also confirms this dependence, because stable photic anoxia zone allows to form big amount of aryl isopre-noids and vice versa, and aeration, in turn, leads to an increase of Pr/Ph ratio.
