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.
