Geologic factors of non-anticline traps forming in Dnieper-Donets aulacogen special oil and gas accumulation zones

Abstract

In DDD and Donbas northern boundary numerous non-anticline traps of different types have been discovered, their territorial spread characterized by significant diversity. In some zones definite trap types prevailing in one or other stratigraphic complexes can be distinguished, others have their interrelation balanced. It looks like possible and expedient to differentiate the Region territory with marking out of oil and gas accumulation zones (OGAZ), considered as search megaobjects. Zones where proper traps have not been discovered yet, but where traps forming auspicious conditions exist, attributed to potential OGAZ. 17 real and 5 potential OGAZ have been defined.
