Abstract

Summary

Thorough lithologic-and-petrographic research, fulfilled by means of complex microscopic research of Paleogene reservoir-rocks in cores and thin sections, points at wide development of lithogenetic fractures, opening of which is mostly equal to the first tens of micrometers.

By methods of statistical processing the data obtained from microscopic analysis in thin sections, it was established that there exists a regularity of microfractures spreading in the zones of intensive lithogenetic fracturing of Paleogene reservoir-rocks of the Precarpathian Depression. It was proved that the conditions of lithogenetic fracturing formation can be dated to sediment-genesis stage influenced by seasonal variations of sediment-accumulation conditions.

It was revealed that oil-saturated layer-by-layer lithogenetic fractures are good filtration canals, providing considerable flow rate of operation wells. Therefore, it is necessary to prevent fluid-conducting fractures from closing during hydrocarbons pumping out of them during wells development.
