Geodynamic processes role at diapiric folds formation of absheron oil-and-gas-bearing structures
B.S.AslanovArticle is devoted to a role of geodynamic transformations in formation and evolution diapiric folds of Absheron oil-and-gas-bearing region area. In particular, it is a question about Tyurkan block of structures Gala-Tyurkan-Govsan. Numerous materials about this structure on the basis of which among scientists and experts the certain opinion on a tectonic structure was formed are published. More than century on Gala block of this structure high-quality oil is extracted, and for today a perspective reserves isn’t exhausted in this. On the other hand, representation about its genetic formation is very vague: one assume, that formation of hydrocarbons is connected with safe tectonics (alternation of anticlinorium and synclinorium), others - with migration of mineral oil from depth. At all the role of geodynamic processes at formation diapiric folds remained outside of sights. Results of gravity works executed by “Geophysical researches” laboratory of Scientific Research Institute on Prognosis & Studying of Earthquakes gave a new representation about tectonics of this structure, especially about block Tyurkan. Analyzing the received material authors assume the followings: – Gala block of structure Gala-Tyurkan-Govsan is represented by horst-shaped fold and Tyurkan - graben-shaped; – the geological nature of local maxima of a gravitational field in a reduction Bug is diapiric structures which have formed as a result of compressing forces in this region.
