Oil source rocks, reservoirs and seals are identified. The tectonic zoning scheme is substantiated, the structural characteristics of the faults and the lithologic-facial features of the section are given. A complex multi-stage tectonic evolution has been identified. Potentially promising stratigraphic oil and gas complexes have been identified – Jurassic (Mesozoic) and Upper Devonian (Famennian) – Lower Carboniferous-Permian (Paleozoic). The deep structure of the region is illustrated by a geological and geophysical section. The correlation of the stratigraphic range of hydrocarbon potential of the Alakol basin was carried out. A probabilistic forecast for the search for crude hydrocarbons is substantiated. On this geological and geophysical basis, the design of the borehole was developed and its position for opening the cover and basement rocks was outlined.</p>Alakol basinstructural-tectonic analysislithologic-stratigraphic sectionstratigraphic correlationlithological and paleogeographic reconstructionshydrocarbon potentialborehole designАлакөл алабықұрылымдық-тектоникалық талдаулитологиялық-стратиграфиялық кесіндістратиграфиялық корреляциялитологиялық және палеогеографиялық қайта құруларкөмірсутек потенциалыбұрғылау ұңғымасының құрылымыАлакольский бассейнструктурно-тектонический анализлитолого-стратиграфический разрезстратиграфическая корреляциялитолого-палеогеографические реконструкцииуглеводородный потенциалконструкция буровой скважины1.Bespalov VF.
