Purpose. To set the spatial-temporal features of lithophysical structure of the Middle Maykopian strata of  the Black Sea - Northern Crimea oil and gas district with the aim of localization of prospective oil and gas objects. Method. Lithology-petrographical, lithmological analyses, lithophysical interpretation of boreholes lithologic sections. Results. The models of lithophysical structure of the Middle Maykopian deposits have been created by separate sections that allowed defining the features of spatial-temporal development of aquitard horizons of regional, zonal and local distribution and reservoir-rocks of different types (porous, fissure). Domination of porous type reservoir-rocks is set on the northern (Tavriyska and Tendrivska areas) and southern (Desantna. Gamburceva, Selsky areas) sides of the Northern Crimea depression and fissure – in his axial part (Golitcyn, Flangov areas). Scientific novelty. First on the basis of lithophysical interpretation of lithologic sections of the Middle Maykopian deposits on separate boreholes the spatial-temporal features of distribution of aquitards and horizons of fissure and porous reservoir-rocks are determined. Practical significance. The prospective oil and gas objects of anticline (structures of Golitcyn, Schmidt, Mizhvodnenska, Shtormova, Archangelsky) and non-anticline (Tendrivsko-Tavriyska, Odesa-Osetrova, Carkinite-Borysivska areas) types are distinguished.
