Annotation:
The Paleozoic deposits of the southwestern Turanian plate, which are part of the foundation, are considered as a promising area of exploration for oil and gas. The primary sedimentary rocks composing the foundation have lost their reservoir-filtration properties in the process of metamorphogenic transformations. Under these conditions, carbonate rocks are more favorable for the formation of secondary reservoirs. The analysis of deep drilling materials, high-precision large-scale aeromagnetic surveys and seismic data made it possible to identify and trace the distribution zones of Paleozoic carbonate strata in the studied region. It is shown that reef structures can be found within their limits. This is confirmed by the products of their destruction and faunal remains found in the overlying sediments. It has been established that, at least in some areas, carbonate deposits entered the daytime surface in later geological epochs, which could lead to the formation of buried weathering crusts and a significant improvement in their reservoir potential. The results obtained can be used in the study of the oil and gas potential and the search for hydrocarbon accumulations in deep-submerged rock complexes and in other oil- and gas-bearing regions of the Scythian-Turanian Platform.
