Abstract

In the paper we have analysed hydrocarbon deposits of the Western region according to their belonging to the tectonic zones, stratigraphic complexes, types and depths of occurrence. The law-governed nature of alteration in physical-chemical properties of oil and gas, hydrogeological and geochemical peculiarities of productive thickness were studied, haloes of the distribution of gas of hydrocarbon and non-hydrocarbon composition outcrops of fluids were mapped. Problems of the formation of hydrocarbon accumulations were considered. According to the results of integrated analysis of different geological factors, besides the main factors of oil and gas presence – structure, reservoir, cover – additional criteria were proposed. In the direction to the deposit, the nitric-methane gases are changed into sufficiently methane and hydrocarbon-methane ones, and values of saturation pressure are comparable to the formation pressure. Indication of oil-gas presence are water-soluble organic matters of oil origin: bitumen, phenols, hydrocarbons, naphthenic acids as well as the presence of condensation waters or their mixture with formational waters. Probable indicators of hydrocarbon accumulations are sulfides of zinc, lead, copper in rocks. For the existence of the deposits the hydrogeological closing of the bowels is necessary: small velocities of the formational waters, their high mineralization, metamorphism intensity, chlorine-calcium type of waters. Natural oil-gas showings as a reflection of deposits that occur at a depth serve as criterion for estimation of prospects of the oil-gas presence in the open territories. The example of substation of prospecting objects is given according to criteria of the oil-gas presence in the platform autochthone under the overthrust of Pokuttia-Bukovyna Carpathians.

Abstract

For the predictive appraisal of the perspective exploratory territories as well as prediction of separate producing horizons of prospecting and exploration areas for oil and gas it is necessary to establish the regularities of distribution of already explored deposits of hydrocarbons with structural-tectonic construction, lithological-stratigraphic features, hydrogeological and geothermobaric conditions of oil- and gas-bearing region taken into account.
Interconnection between geothermobaric parameters and the phase state of hydrocarbons in the vertical section should be an important factor for the solution of the posed task.
Within the limits of the Eastern oil- and gas-bearing area of Ukraine, the spatial zoning is established in the location of gas, oil and gas-condensate deposits. As a whole, the distribution of temperatures and pressures at different depths, average geothermal gradients, gradients of the lithological-stratigraphical horizons of the same name (sustained both as to the area and thickness) are closely connected with the deep geological structure of the studied region (area) and confirm the existing notions of the role of tectonic, lithological-stratigraphic and hydrogeological factors in the formation of the thermal regime of sedimentary basins.
Vertical zoning of the distribution of hydrocarbon deposits of oil- and gas-bearing horizons was developed according to geothermobaric parameters of the north-western part of the Dnieper-Donets Depression and 8 areas from 15 ones of the Eastern oil- and gas-bearing region, namely: Monastyryshche-Sofiivka and Talalaivka-Rybalske oil- and gas-bearing areas, Glynsk-Solokha gas- and oil-bearing area, Ryabukhyne-Northern Golubivka and Mashivka-Shebelynka gas-bearing areas, Rudenky-Proletarske oil- and gas-bearing region, Krasna Rika gas-bearing area and also oil- and gas-bearing area of the Northern edge.
Revealed regularities of the distribution of formation temperatures, pressures, geothermal and thermobaric coefficients with peculiarities of the tectonic structure of the Dnieper-Donets graben taken into account will make it possible to solve theoretical problems connected with hydrocarbon migration, the formation and preservation of deposits in more well-founded way that will make it possible to conduct prospecting for new fields at great depths within the studied territory more effectively,
