At the present stage, the development of the oil and gas industry of the Russian Federation is impossible without replenishing the resource base, and therefore an urgent task is to conduct research, prospecting and evaluating petroleum potential in undiscovered areas of fields. The aim of the study is to conduct a comprehensive assessment of the reservoir of the productive formation of the Kanevskoye field. We have carried out mineralogical and petrographic studies, laboratory studies to assess the effective porosity of the core sample by the saturation method, particle size analysis, X-ray diffraction analysis. Our studies have shown that the considered initial sands under consideration, which formed the reservoir rocks of the productive horizon of the Kanevskoye field, were formed by coastal or beach type marine sediments. This is confirmed by the poorly rounded shape of the grains and the presence of glauconite in the rocks. The studied core sample is a fine-grained glauconite-feldspar-quartz sandstone with an admixture of aleurite fraction, with semi-rounded grains, pelitic cement, basal and porous-basal, silt-psammitic structure. The total porosity is 14.3 %. A comprehensive assessment of the reservoir of the productive formation of the Kanevskoye field has been carried out. The reservoir is productive. Therefore, it is necessary to make a project for conducting geological exploration.

At the present stage, the development of the oil industry of the Russian Federation is impossible without replenishing the resource base, and therefore an urgent task is to analyze and assess the conditions and characteristics of oil-andgas content in unexplored regions.Purpose of the study is an analysis and an assessment of reservoir properties of rocks of the Aptian horizon Р1+2- К2 within the Akhlovskaya structure.We analyzed the graphs of the distribution of indicators in wells R-212 and R-213 in the Akhlovsky area and concluded that the reservoir is heterogeneous, and there are interlayers of mudstones with other reservoir properties and geophysical characteristics. The following pairs of parameters (porosity coefficient and oil-saturated thickness of rocks, rock resistivity and porosity coefficient, rock resistivity and oil-saturated thickness of rocks) have a significant positive correlation. Having studied the distribution of indicators in the Akhlovsky area for wells R-212 and R-213 along one horizon, we concluded that these indicators differ very slightly, which indicates the homogeneity of the reservoir properties. Qualitative indicators Qualitative indicators don't change. Thus, we can expect similar indicators within the entire area of the explored layer Р1+2- К2 in the territory of the Akhlovsky area.

Oh the basis of primary c-avis of late singenetic quartz in blastomilonites of granitic composition, which from granite- gneissic monocline in Pervomaisk fault zone, it is demonstrated that bifeldspaort granite formation occurred in the conditions of tension followed by transtension and transpression with realization of translation and recrystallization mechanism is demonstrated. 

The paper explores stages in granitization of the leucocratic blastomylonites intersected by melanocratic tectonites. The study focuses on difeldspar migmatites and gneissoid granites, variegated in texture, structure and composition, which are the tectonites of the Pervomaiska gneissoid granite monocline. The prevalent blastomylonites in the study area are light gray, light pink and pink, average-to-coarse-grained, pegmatoid, porphyroclastic, heavily schistose and banded.Early leucocratic pegmatoid tectonites occur subvertically and are intersected by melanocratic tectonites at 45o. Showing no major recumbency or discontinuity of the directive structures, the intersection provides evidence of a brittle-ductile deformation. Rotational amplitude and vector being vague to define, the juxtaposition of the deformed fragments of the pegmatite vein in the late tectonites is assumed to have been affected by low amplitude of shear or thrust deformational processes, though. The hypothesis made is further confirmed by the occurrence of Fsp porphyroclasts as well as Fsp quartz aggregates.The thickness of the melanocratic layer observed within 3 m makes 8-10 cm, with an azimuth being 240-260o, and the gradient making 45-55o. This is contrasted to leucocratic tectonites with an 80o azimuth and an 85o gradient.Melanocratic tectonites are of fine-grained texture and Fsp biotite-quartz chemistry. They are identified based on blastomylonite fine-grained granoblastite texture with traces of relict Fsp and garnet porphyroclasts, as well as low mineralized quartz lenses that are similar to those of the basic gneissoid granites. Blastasy is quite mature, while sections reveal distinct blastomylonite schistose features. Minor porphyroclasts can be seen throughout the study area, which suggests permanent hetero-axial brittle-ductile deformation.The leucocratic tectonites being intersected by the melanocratic ones is obvious. What raises further consideration is the temporal correlation between the deformational processes in question and the Palaeo-Proterozoic granitization. Interestingly, microtectonic evidence suggests late and post granitization deformations having been in sync, with granitization strains showing considerable variability.
