Annotation:

The concept of the fault-block structure of the Antipovsko-Balyklei-River deposit is considered. The paradigm of the plicative variant of the deposit structure adopted for deposits of this type is conditional. Discharges and pre-discharge structures on the same age sediments form structural blocks (steps), sinking to the center of the depression from west to east, and within the trend from north to south. The probability of discontinuous disturbances is implied by geomorphological features (terrain analysis, erosion and neotectonics), according to reinterpretation of seismic materials at the level of Kynov deposits (D3kn) and petrophysical materials (access to the wedging line of lithologically limited trap rocks with high and increased porosity and in some cases with increased effective oil-saturated thickness).
