Search features of hydrocarbons in the lower oil and gas complex for the different subregions of the Dnieper-Donetsk cavity Article 2. The oil and gas deposits search areas in the Romensko-Okhtyrsky subregion

Abstract

Generalized previous studies and are further evidence of productivity lower oil and gas complex (IPC) in Romensko-Ohtyrsky subregion of Dnieper-Donets cavity. Geodynamic conditions of formation of the subregion performances Precambrian crystalline basement in some way connected with updated movements of lower Proterozoic structure, which was the reason for the selection of three fundamentally different kinds of them. In contrast to the northwest in the sub-region main area occupied by no speeches, and depression. However, the assumptions about the requirements for posting wells, and test them unchanged for deposits of hydrocarbons will be looked at the same unconventional natural reservoirs: traps, wedge shape type olistostromes, secondary decompressed Precambrian basins. Based on the dualistic hypothesis of the origin of hydrocarbons in the presence of large sedimentary cover subregion and even unique field is regarded as an important criterion in search of NK significant reserves of hydrocarbons. The reduced projections search facility on the slopes of the various species and especially the third type, which likely just be found large deposits. In this work the only objects that lie no deeper than 6 000 m. More items will be shipped attractive when the subregion get good positive results of these deposits.
