Fault-block structure of fields according to field-geophysical data

The article shows that a complex interpretation of diverse information supported by geochemical, hydrodynamic and other studies proves a complex (fault-block) structure of the Carboniferous and Devonian depositions of the fields at the western flank of the Pre-Caspian trough and its platform slope. It promotes formation of hydrocarbons of traps favorable for a congestion, they play a role of bringing channels on which there is a migration of fluids from the deep-shipped deposits.
