Dnieper-Donets Basin

The second part of the article studies the tectonic conditions and natural mechanisms of tectonic inversion of the Dnieper-Donets Basin and the Western Donets Graben. Method. The research uses the original method of reconstruction of fields of tectonic stresses and deformations. It also makes tectonophysical analysis of geostructures was used. The analytical base of the research consisted of the latest materials of geo-mapping, numerical modeling of deformations of the southern edge of the Eastern European platform and comparison of model and reconstructed stress fields. Results.

Aim. Geodynamic interpretation of previously obtained 3D density and magnetic modeling results, and data on consolidated crust fault tectonics of the Dnieper part of Dnieper-Donets basin (DDB) in the light of its formation mechanism.

Purpose. To investigate lithosphere heterogeneity of the Dnieper part of the Dniper-Donets basin and its stages after 3D gravity and magnetic modeling using the data of DDS, seismic tomography, geological structure of the Precambrian basement, and sedimentary cover for subsequent geodynamic interpretation.

In the paper, a method and results of integral modelling of velocity distribution of seismic waves are presented. A method for processing and interpretation of vertical seismic profiling data to estimate average, vertical and layer velocities is suggested. Based on these data, an integral model of velocity distribution for a most promising part of Dnieper-Donets basin was built. Results of the work can be used to build 3D depth models of oil and gas deposits, to refine time-depth relationships in the existing models.

The aim of the study is to determine the volume of distribution parameters and petrophysical properties of rocks in the unconventional hydrocarbon fields are based 3D-modeling. Used Methodology is related to the analysis of geological and technological parameters and conduct three-dimensional modeling.
