Abstract

Distribution features of formation waters in Karkinit-Northern Crimean deep were studied; the conditions of chemical composition origin of formation waters have been studied as well.

The regional features for the distribution of formation waters and the conditions of their chemical composition forming of the Lower Cretaceous complex are established.

The formation waters are salty or saline and commonly have low metamorphism intensity.

The formation waters of the Lower Cretaceous complex are salt with often a low degree of metamorphosis.

The values of the variation coefficients of five principal components (mineralization, (Na + K), chlorine (Cl), bromine (Br), and the water sampling depths) are estimated to range from 28.73 to 57.14 %, which indicates insignificant variability each of these indicators; this characteristic does not depend on the type of water and place of sampling.

The seven objects of the correlation such as mineralization, chlorine, calcium, ammonium, bromine, sulfates and hydrocarbonates are closely associated with each other.

The land waters are commonly of calcium chloride (Cl.Ca) or hydrocarbonate natrium (Hyd.Car.Na) type, whereas in the water area all variety of formation waters has been recognized. Formation waters of Late Cretaceous shelf complex as well as formation waters at Tarkhankut peninsula have close relation between chemical components, low variations in the composition of macro- and microcomponents. Therefore, the formation waters of these regions could be formed in quite similar conditions.

The characteristic features of the shelf formation waters are high sulfate content, despite the fact that waters complex occurs at great depths.

At the same time, a decrease in the metamorphism intensity is observed as well as an increase in the Cl/Br ratio up to 1000 or more, caused by low bromine content. It is apparent that such characteristic can be the result of extrusion of water at the late stages of clay rocks dehydration. Paleoinfiltration processes in Lower Cretaceous complex may be considered as an alternative explanation.

High gas saturation in the waters of the folded basin bed has been recognized at Golytsyno area and at the Tarkhankut peninsula (Melova, Oktyabrska, Berezivska and Western Oktyabrska areas). This allows us to predict the prospects of the Lower Cretaceous sediments of the Karkinit-Northern Crimean deep.

Keywords

Karkinit-Northern Crimean deep, Lower Cretaceous aquiferous complex, hydrogeochemical conditions, sedimentary waters, dissolved gases.

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 geochemical features of natural waters of the SE “Sanatorium-resort medical center “Shklo” are established by researches of their ecological-geochemical composition and anthropogenic influence.
The mineral water “Naftusya-Shklo” from the pump room in the territory of the sanatorium is selected and analyzed, which is recognized as an analogous to water “Naftusya” by the biological action. The composition of water is hydrocarbonate sodium, having mine-ralization of 0.76 g/dm3, the total hardness of 0.55 mg-eq/dm3, sulfate content of 0.64 g/dm3, and Eh – −79 mV.
The sample of water from baths, which is fed from a depth of 129.0 m, is investigated. Therapeutic hydrogen sulfide water is classified as sodium salt-calcium sulfate with mineralization of 2.97 g/dm3 and high sulfate content (1.76 g/dm3). The balneological active component of the therapeutic water is hydrogen sulfide, the content of which is set at 101.75 mg/dm3. The common feature of these waters is the negative values of the oxidation-reduction potential, which is due to the presence of relatively high content of H2S and HS−.
In addition to the mineral, a sample of water from the water pipe (drinking water from the Opillia suite of the Lower Neogene) was studied. According to the salt composition, it refers to sulfate-hydrocarbonate sodium-calcium with mineralization of 0.53 g/dm3. The content of the determined macro- and microcomponents do not exceed the maximum permissible concentrations for drinking water, which indicates the absence of influence of the lower horizons.
The water sample was also selected from the largest lake of the park, the sanatorium “Shklo”, which is not related to reservoirs with a special regime of protection, therefore access to it is free. The salinity of water refers to chloride-sulfate-hydro carbonate sodium-calcium with mineralization of 0.35 g/dm3.
Two samples of water from the Shklo River after its leak from Yavoriv lake showed that these waters are weakly mineralized, weakly alkaline, calcium hydro carbonate sulfate or sulfate calcium. Quantitatively, sulfate ions are 2–3 times more than hydrocarbons. The content of sulfates, Sodium, Calcium, Magnesium is also high, indicating their contamination. Further down the salt content decreases as a result of mixing with the water of droplets. Several sources of supply of sulfate-ion can be named: karst waters formed on gypsum anhydrite; reservoir waters of the Upper Badenian limestones, hydrogen sulfur of the formation waters of the Badenian horizon; hydrogensulfur, formed as a result of reduction of sulfate at the bottom of Yavoriv lake. Ecological and geochemical parameters of water of surface water reservoirs and watercourses generally also correspond to state standards for their use as recreational.

Keywords

drinking water, ecological-geochemical parameters, anthropogen influence.
