Role of factor of dynamocatagenetic intensity of sedimentary deposits in processes of oil and gas generation and migration has been proved in the works of some researchers. On the base of synthetics of data bulk conditional index of gynamocatagenesis has been offered by A.N. Reznikov. This index takes into account the reflectance of vitrinite and amounts of exponential geochronotherma that shows cumulative change of organic matter and history of their thermal evolution. The maximum paleotemperatures for a number of objects was estimated by thermobarogeochemical method to eliminate interdependence of the readings RРѕ and maximum paleotemperatures. Materials of 4050 intervals at 340 crustal blocks were processed to highlight the geodynamic types of sedimentary basins. These blocks are dedicated to different geostructural elements. Geodynamic classification of the earth crust blocks was developed, and 6 genetic types of pools are allocated. A description of each of these types are presented, the parameters of the formation zone are installed in them. This study confirms the modern concepts about the leading role of dynamometers in the oil and gas formation and oil and gas accumulation. Estimation of phase state of hydrocarbons of various blocks is presented in the work. Geosinergetics method enables the assessment of the geological oil and gas resources of in all sedimentary basins at depths up to 9 km.
