The Analysis of the Wave Field of the 3D Seismic, Tectonic Structure of the Basement and the Vasyugan Series of the Western Siberia

The aim and objective of this research was to A) study the seismological properties of the wave field in the range of reflections from the surface sediments of the basement and pre-Jurassic age sediments of the Vasyugan series of the upper Jurassic, B) study of the influence of geodynamic and disjunctive tectonic environments, predictable according to the interpretation of seismic data In) specification of the characteristics of faults, detection of fracture zones in rocks within the developed deposits. As a result, dynamic analysis, wave field, dedicated to the sediments of pre-Jurassic age - the Foundation is established, that the boundaries identified seismodynamics zones of pre-Jurassic complex are areas of “hard” tectonic setting is zones of increased fracturing (decompression, edge sections of the Horst-Graben) extending above the incision to the depth of the upper Jurassic sediments (zones of subvertical destruction). It is established that zones of increased fracturing of reservoirs reservoir UV1 are in direct relation with the tectonically “strained” areas in the Paleozoic basement, confined to the limits of the Horst - Graben. Identified areas of high fault tectonics and their influence on production rates of hydrocarbons and the ratio (%) water-oil in the formation fluid. Identification of seismic facies that are directly related to the geological forms of the Foundation and the Vasyugan series of the.
