Abstract

The article is the first part of a trilogy devoted to the study of post-rift deformations of the riftogenic structure of the Dnieper-Donets paleorift. The mechanisms of collision warping of the horizons of the sedimentary cover of the southeastern part of the Dnieper-Donets depression are considered.

According to the previous mapping data, the tectonic deformations of the sedimentary cover were controlled by systems of faults of the north, north-west, and south-east vergence. The lattices of tectonites of the Hercynian, Lamaric, and Attic generations determine the specific “cross-thrust” structure of pushing. Overthrusts and linear folding of three generations permeate the sedimentary sequence of the transition zone from east to west for hundreds of kilometers within the eastern part of Izyumsky paleorift segment.

The analytical base of the research was the materials of geological mapping of the zone of the junction of the depression with the Donets fold structure. Using field definitions of the tectonite vergency of the Hercynian, Laramide and Attic phases of tectogenesis, the original method of reconstruction of tectonic deformation fields and tectonophysics analysis of structures, collision deformations of the sedimentary cover of the south-eastern part of the Dnieper-Donets paleorift are studied.

The tectonophysical analysis of tectonites of different ages indicates that together they control the cover-thrust and folded deformations of the riftogenic structure. Overthrusts and linear reverse-folding of three generations form the West-Donetsk integumentary-folding region, within which a segment of the same name tectonic thrust is distinguished. By pushing the system of repeatedly deformed, crushed into folds of geomass sedimentary rocks on weakly deployed syneclise deposits, the riftogenic structure of the south-eastern part of the basin is completely destroyed. The structural-tectonic framework of the allochthone, pushed from the side of the Donets structure, is composed of dynamically conjugated lattices of Hercynian, Laramide, and Attic tectonites. They control the echelon backstage of linear reverse-folds, tectonic plate-covers of transverse extrusion of sedimentary geomass from axial to airborne zones and folded covers of longitudinal thrust from the south-east.

The riftogenic structure of the transition zone between the Dnieper-Donets basin and the Donets folded structure was completely destroyed by deformations of three generations of platform activation. The dynamically coupled tectonite lattice, the overlays, and the folded zones of the Hercynian, Laramide, and Attic generations jointly form the West-Donets fold-fold region within its boundaries. The main tectonic element of the area is the eponymous subregional tectonic thrust segment. The central structural zone is Veliko-Kamyshevakhskaya, Novotroitskaya, Druzhkovsko-Konstantinovskaya and Main anticlines. The central zone divides the body of the segment into two tectonic regions according to the tectonic style and intensity of deformation of the sedimentary sequence. The northern part is occupied by the Luhansk-Kamyshevakhsky region of the rocky-layered linear folding of the thrust, and the southern part is the Kalmius-Toretsky region of scaly tectonic covers.

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,

Abstract

The influence of exploitation and abandonment of coal mines of the mining complex of Lviv-Volyn coal basin on the ecosystem of the region is considered. The main ecological problems of the territory are analyzed. It is established that the high technogenic pollution of the Chervonograd geological and industrial region is facilitated by the inflow of highly polluted drainage waters from the mine heaps and rock waste heaps of the Chervonograd Central Mining Plant into soils, surface, ground and underground waters. The negative impact of the heaps is caused by the high level of fault tectonics and fracturing of the bedrocks, the flat surface of the area. The influence of technogenic objects on the atmospheric air quality is analyzed. The main causes of the atmospheric air pollution are stationary sources of pollution.

Technogenic objects have a significant impact on the quality of the the atmospheric air. The main role in the structure of pollutants belongs to sulphur anhydrite, carbon and nitrogen oxides, dust and soot. The amount of pollutant emissions into the atmospheric air from stationary sources of pollution for Chervonograd and Sokal districts has been analyzed according to the data of the Main Statistics Office in Lviv region.

To prevent further deterioration of the ecological situation, it is recommended to form flat heaps, their reclamation and landscaping with the obligatory covering of the surface with a layer of neutral rocks, to keep measures to prevent burning of heaps. To stabilize the situation and to prevent further contamination of soil, surface and underground waters, the stable network of observations on the state of the geological environment, systematic geological and environmental monitoring should be carried out.

Abstract

Sudden coal and gas outbursts in coal mines are one of the most harmful and at the same time, dangerous gas-dynamic phenomena faced when coal producting. The sudden coal and gas outbursts is the evanescent destruction of the bottom-hole area in the coal bed, which develops from the bottom into the depth of a massif, and the crushed coal with gas is thrown to a long distance from the bottom into the mine, destroying everything in its way, creating the conditions for explosion and fire breaking-out. Sudden outbursts lead to significant material losses for the recovery from an accident and in some cases injuries and human losses. The problem of reliable prediction, prevention, and control of sudden coal and gas outbursts at coal mines remains extremely urgent, due to the constant increase in the depth of mining operations. The analysis of the experience of predicting and preventing the outburst hazard in coal beds of Donets and Lviv-Volyn coal basins is analyzed. At Donbas mines since 1906, there have been more than 7.5 thousand sudden outbursts. Although mining had now reached considerable depths (from 300 to 600 m), the emergence of coal and gas outbursts have not been recorded. The purpose of the research is to determine the depth of the possible emergence of sudden coal and gas outbursts in the LVB, with regard to the peculiarities of the geological structure of the coal-bearing strata in the Lviv-Volyn coal basin.

The comparative possible depth estimation in the manifestation of the outburst hazard of the coal beds in the LVB is given. It is calculated according to the normative technique and performed according to the formulas obtained by the statistical analysis for the actual position of the minimum depth of coal and gas outbursts at the Donbas mines. The absence of sudden coal and gas outbursts at LVB mines on the coal beds, which are hazardous according to the prediction data, is performed according to the methods regulated by the normative documents and compiled by the experience of studying the outbursts in Donbas, is explained by the differences in the geological structure of the LVB, the main of which is the presence of thick mass of covering deposits and a significantly greater depth of the methane gas zone. The application of the empirical formulas prediction, which includes the methane gas zone depth index, allows us to account for these differences and it is much more reliable to determine the possible depths of sudden outbursts for LVB, which, all other things being equal, should be greater than in the Donbas. In particular, according to the performed calculations, the outburst hazard situation at the “Stepova” mine is predicted at depths of more than 700 m. As prediction indices for the calculations, values of methane gas zone depths of 450 m were adopted, and the minimum value of volatile-matter yield was 33.3%.

This approach can be proposed for predicting the coal and gas outbursts hazard in other Lviv-Volyn basin mines. To determine the predicted depth of the possible emergence of sudden coal and gas outbursts, it is advisable to take into account the depth of the methane gas zone in the prediction calculations.

Abstract

The article reviews the chemical structure of type II kerogen. The changes that occur with the structure of type II kerogen as it passes through the stages of catagenesis from immature to post-mature are evaluated. Structural models of type II kerogen at different stages of catagenesis are presented: both obtained empirically after studying the structure by physical and chemical methods and the results of modelling by molecular dynamics method.

Methods of equilibrium thermodynamics are used to calculate the composition of the kerogen–gas system for crust sections in the range of 1–20 km with a heat flux of 40 to 100 mW/m2. The composition of kerogen/fluid geochemical system is calculated using the E. T. Jaynes formalism. It boils down to determining the optimal distribution of 5 elements (C, H, O, N, S) among the 44 additive constituents of the solid phase (i. e., type II kerogen) and other individual components that are included in the system (CO2, H2O, H2S, NH3, CH4, C2H6, C3H8, i-C4H10, n-C4H10, i-C5H12, neo-C5H12, n-C5H12).

Comparison with the experiments showed that the results of the calculations do not contradict the experiments, with study the structure and changes in type II kerogen with increasing degree of catagenesis. In the analysis of changes in the concentrations of water, carbon dioxide and hydrogen sulfide, it is founded that kerogen could be not only a donor of atoms for gas components, but also their acceptor in contact with a high-energy fluid stream. It is shown that the determination of sulfur-containing atomic groups of kerogen by thermodynamic modelling yields gives more reliable results than molecular dynamics methods.

Established is that the concept of “methane-graphite death”, which takes place in the state of thermodynamic equilibrium in the transformation of organic matter, is erroneous. The calculation shows that the composition of the kerogen–gas system, in addition to methane and carbon, includes solid-phase heteroatom groups, various additive components of aromatic structures and gases, both organic and inorganic. The distribution of elements between the additive components of kerogen and gases in this system controls the pressure and temperature in a complex way. The nature of changes in hydrocarbon gas concentrations in equilibrium with type II kerogen indicates the presence of an “oil window” in low-warmed zones within 2–4 km depths.

Abstract

In the paper a model of the formation of the folded-covering-block structure of the Carpathians at a time interval that envelops Late-Hercynian and Alpine events is substantiated. Moreover, this concerns the Outer Carpathians, but the whole Carpathians arch was characterized without going into details, a critical estimate is expressed for application of such terms as terrains, accretion prism, suture, subduction and Transcarpathian fault. It is shown that formation of the Carpathians occurred through several stages under the influence of different-directed, manly horizontal, movements, as a result of which was destruction of early formed  Hercynian continental crust, laying of geosynclinals troughs, formation and further transformation of the basement of the Flysch Carpathians, its collision with Eurasian continental edge, underling of the latter under flysh complex. After completion of these processes mainly vertical movements took place that lineally formed the structure of the Carpathians as folded-covering-block one. As a result of the last event (Pliocene-Pleistocene), a differential development of intensive fracturing occurred with the influx of hydrocarbons and filling traps formed up.

Abstract

It is shown that with the change in pressure and temperature of natural gases in storages gas-holders, different installations one can separate water in necessary concentration from hydrates of hydrocarbon gases in their composition that forms its increased admixture in pipes and in the long run it influences the final heat-producing of the fuel. New approach was proposed as to the determing of heat-producing of natural gas supplied to consumers by the way of substantiation of the necessity to introduce such a unit as cubic metrobar (m3 bar). This would be conductive to determination of the correlation between heat-producing of produced natural gas and gas supplied to consumers, that is to say, determination of quality of consumed gas.

Abstract

On the basis of paleo- and modern hydrogeological sings it was possible to establish a space-time mechanism of formation and reservation of gas and oil deposits in the Bilche-Volytsa zone of the Carpathian oil- and gas-bearing province.

The time interval of their forming applies on the last cycle of the hydrogeological time. Geodynamic and secondary geostatic loadings, that manifested themselves during the dynamo-elision stage (Late Badenian – up to the present) the development of which was caused by thrust motions of the covers, turned out to be the factors of migration of aqueo-hydrocarbon mixtures deep underthrust structures of the Inner zone. Time calculations for reservation of deposits of gas fields have determined their age which does not exceed 6 million years.

The south-western trend of motion of paleo- and modern infiltration waters in combination with reversed dynamo-elision have caused here the existence hydrodynamically balanced system squeezed between them which differs by favourable conditions for the formation and reservation of hydrocarbon deposits.

We have ascertained the connection between piezomaxima and areas of tectonic dislocation, mainly transverse, that points out the ways of transsference of hydrocvarbon mixtures from deep-seated horisons. Discharge areas (perspective on a plane of searching for new deposits) are limited by local piezomaxima on the background of regional fields. Areas of paleopiezominima in the near-fault part of the Ugerske-Kosiv blocks at the boundary with the East European Platform are favourable for localization of hydrocarbon deposits.

Results of the baroosmotic analysis of hydrogeological conditions of gas and oil fields have revealed baroosmotic flows of waters molecules in the thickness of clay rocks, their intensity and directions of motion and connections with deposits.

Abstract

The paper describes the tectonic position of Marmarosh zone of rocks and determine its place in the structure of the Ukrainian Carpathians. Shown is the history of the study of igneous rocks. The comparative analysis of the views on the structure and position of the Marmarosh klippen belt in the structure of the Carpathians processed by the literature was carried out. At the end of the article the researchers compared views on the structure of Foreign Affairs, highlighted the main features of the geological structure and tectonic zoning area.

Some similar features of  rocks composed of Marmarosh klippen belt, namely formational, to a lesser extent, the morphology of the folded and dislocations with a break of continuity history of even-aged species of complexes the Marmarosh zone of rocks is considered as NW continuation of Marmarosh massif that was torn from its substratum in the tectonic evolution of the region. These tectonic elements of different times and different phases of folding, but the final phase of tectonogenesis was manifested are almost simultaneously during the Miocene. MKB is a special category of tectonic structures associated with faults, of considerable length and long stage of development, is so-called near-fracture or suture structures and delineates two different areas with sharply different geological development history, geodynamic conditions of formation, stratified formations, independent tectonic regime. The structure is characteristed by the set of formations – sedimentary, igneous, metamorphic.

As a result of structural and tectonic studies the Marmarosh klippen belt is a consequence of Albian movements where appeared blocky dislocation and Post-Oligocene folding and formation of small intrusive bodies. Modern look of the band was formed in Oligocene time at neotectonic stage of development of the Carpathians. MKB is not correlated with any of the Carpathians area, although it has similarities with some elements, such as Marmarosh massif, but it different by a character of section and especially by peculiarity of the section of the Lower Cretaceous.

One of the conditions for further study of Marmarosh klippen belt is integrated research, including the study of facies changes of the nature of the thickness, more mapping of folded and discontinuous structures, further development of stratigraphic scheme of the area, the analogy of even-aged sediments and similar genesis formations of adjorning the territories both on the – territory and abroad of Ukraine. In this comprehensive analysis the Marmarosh klippen belt may get a proper understanding of its nature and place in the structure of folded Carpathians.

Abstract

The formation of the temperature regime of the Dnieper-Donets depression is determined by the magnitude of the deep heat flux, the structural and tectonic features of the region, the lithology of the sedimentary complex, the occurrence of a thick complex of chemogenic and volcanic rocks in the region, as well as hydrogeological conditions.
Based on the analysis of factual geothermal material on wells, obtained during geophysical studies, measurements of temperatures and geothermal gradients, measurements of temperatures during testing of productive horizons, as well as from literary sources, the interpolation of factual geothermal material is carried out. The geothermal parameters characterizing the temperature state of rocks and fluids of different tectonic zones of the Eastern oil- and gas-bearing region have been determined. Schemes of temperature distribution at depths of 2000, 8000 m, average geothermal gradient, depths of isotherms 150 °C, 180 °C are given and regularities of distribution of geothermal parameters are analyzed. The lateral zoning of the geothermal parameters distribution of the region is established, the zones of their maximum, middle and low values are distinguished. Taking into account the peculiarities of the tectonic structure of the Dnieper-Donets graben, as the sedimentary complex is submerged, a gradual replacement of oil by oil and gas fields and then by the gas ones occurs from the northwest to the southeast. Geothermal parameters characterize the geothermal activity of the subsurface and allow to determine its zonation, as well as to predict the phase state of hydrocarbon systems at great depths.
