Аннотация: The zones of deconsolidation and consolidation in the lower parts of the sedimentary cover and in the basement are considered as an important exploration indicator of oil-gas accumulation zones. The described zones are mapped using geodensity modeling (in a gravity field) in the MZ-PZ basement and Cretaceous deposits of South SakhaПоказать полностьюlin, as well as in the pre-Jurassic basement and plate complex of the central part of West Siberia. It was found that the most promising zones are confined to the Central Sakhalin Fault and Krasnoleninsk arch in Sakhalin and to the Visim megaswell in the West Siberian plate. Recent prospecting drilling revealed that deconsolidation zones are correlated with hydrocarbon reservoirs. The presented technique of geodensity modeling can be applied for petroleum-geological explorations of structures formed in different geological and tectonic settings. © MAIK Nauka 2008.
