Makyeyeva N. The specific features of geological structure and the prospects of non-structural hydrocarbons traps prospecting in Middle Carboniferous complex of the northern rims of Donbas

The object of the research is the Middle Carboniferous sediments of the Donbas northern edge, the aim of the research is identifying the paleo-tectonic and paleo-geographical specific features of sedimentation of the Middle Carboniferous sediments of the Donbas northern edge as well as of the structural, lithological and stratigraphic conditions to form the non-structural traps and to determine the primary geological and prospecting works direction to prospect for oil and gas; the methods of research are the fascial paleo-geographical and paleo-tectonic analyses, the methods of lithostratigrafic sections correlation, the systematization of geological and geophysical information; the theoretic and practical results are as follows: there have been determined the paleo-tectonic and paleo-geographical specific features of sedimentation of the Middle Carboniferous sediments of the Donbas which is beneficial for the formation of cyclic strata section and various non-structural traps; there have been defined the primary oil and gas prospective directions and objects, there have been developed the recommendations to conduct seismic and prospecting works and deep drilling to prospect new oil and gas pools in the Middle Carboniferous sediments of the Donbas northern edge; the novelty of the implemented lies in having identified the specific features of the reservoir beds development on the grounds of formation by formation correlation of the Middle Carboniferous sediments in the area of Krasnoritsky faults which alongside with seismic data use set up the base to define the sandstone formations between the reference points of Moscovian and Bashkirian stages and confirmed the availability of non-structural traps in the section of the Middle Carboniferous sediments; the degree of implementation - it has been implemented in the area of Krasnoritsky faults; the sphere of use - the production and research geological prospecting organizations.
