Azov-Black Sea region is one of the oldest oil and gas producing regions of Russia. Here are explored and put into the development of dozens of oil and gas fields, are actively being sought new hydrocarbon accumulations. However, in recent years there has been a marked increase in the backlog of proven reserves of fossil fuels on crude oil production decreased efficiency of geological exploration. The solution to these problems is impossible without the development of new models of petroleum and petroleum accumulation in the Earth’s crust, without generating sufficient objective criteria forecast oil and gas. Based on the analysis of multifaceted geological and geophysical material broad development overthrust-and-thrust structures, not only within the mountain-folded structures of the North-West Caucasus, but and adjacent areas of the West Kuban trough, Epihercynian Scythian plate, and the Black Sea basin. Tectonic schemes constructed, structurally balanced sections and geological model of dislocations. The features of the morphology of thrust dislocations formed in the various structural-tectonic zones, patterns of their spatial distribution and formation. A comparative analysis overthrust-and-thrust structures of the Black Sea-Caspian and other regions. Proved that the development overthrust-and-thrust structures of the North-West Caucasus, Black Sea basin and the Scythian plate went on a single model and single geodeformation field stress due to collisional processes in the Caucasus segment of the Alpine orogen. The features of the structure of oil and gas traps in diverse tectonic zones of the region under study, the conditions of formation and distribution regularities of possible oil and gas accumulations, including within complex dislocated zones (North-West Caucasus). With specific examples to demonstrate the role overthrust-and-thrust structures in the localization of oil and gas deposits. Identified promising areas of exploration. The proposals for optimizing hydrocarbon exploration techniques in areas of the dislocation of lateral compression.
