Results of field geophysical investigations and data of litological-petrophysical studies of core samples have been analyzed. A complex of petrophysical and geophysical indicators of rocks of lithological traps in the Lower Carboniferous deposits of the Dnieper-Donets Depression has been developed. It was concluded that the best reservoir rock properties are characteristic for the channel and bar sand bodies, represented with anisomerous quartz sandstones with carbonated-clayed and quartz-clayed-carbonated cement.

In the paper the main principles of the fluidodynamic conception of catagenesis is described. The conception grounds the cyclic nature of catagenesis according to stages of tectonic regime, the features of which influence on secondary rocks alteration mediated by fluidodynamic features. The important role of the lithogenetic processes preservation during the passive substage of exfiltration catagenesis is argued.
